The Old Book of Tang: What Tang China's First Dynastic History Reveals About Early Islam

The Old Book of Tang: What Tang China's First Dynastic History Reveals About Early Islam

بِسْمِ اللَّهِ الرَّحْمَٰنِ الرَّحِيمِ 

"In the name of God, the Most Gracious, the Most Merciful."

For over a millennium, historians have relied on the official dynastic histories of China as among the most meticulously kept chronological records in human civilization. When it comes to the rise of Islam and the Arab conquests, one text stands above all others: the Old Book of Tang (舊唐書 / Jiu Tangshu) , completed in 945 CE under the Later Jin Dynasty during the Five Dynasties and Ten Kingdoms period.

Its lead editor was Liu Xu (劉昫) , a high-ranking official who served as chief minister under the Later Jin. The work draws heavily from earlier Tang dynasty historical records, including the foundational draft by Wu Jing covering the period from the dynasty's founding to the Kaiyuan era, later expanded by Wei Shu, Yu Xiulie, and Linghu Huan. Despite being compiled after the Tang's fall, the Old Book preserves raw, contemporary material—including verbatim documents, edicts, and memorials—that its compilers had direct access to from the Tang imperial archives. It is, in essence, the "first draft" of Tang history, sprawling and detailed, containing information no later source could replicate.

When it comes to the records of the Arab Empire (大食 / Dàshí), the Old Book of Tang preserves something extraordinary: two distinct voices speaking from the same archive.

The first is the voice of the vanquished. Nestled within its pages is a strange and fantastical account—the "Lion's Prophecy"—telling of a Persian camel-herder in Medina, spoken to by a demonic lion, who discovers caves filled with weapons and a mysterious black stone with white inscriptions commanding him to rebel. He gathers outlaws, defeats the mighty Persian and Roman empires, and crowns himself king. For centuries, historians dismissed this as garbled hearsay. But as we shall demonstrate, it is nothing of the sort. It is a masterpiece of Zoroastrian propaganda, a theological horror story crafted by Sassanian refugees—almost certainly including Prince Pērōz III himself—to explain their world's unmaking to their Tang hosts.

The second is the voice of the victors. Alongside this nightmare sits a sober, political chronicle that aligns stunningly well with the official history of the Islamic Caliphates. It traces the genealogy of the Quraysh tribe, names Muhammad as a "brave and wise" leader elected by his people, records the Umayyad succession, documents the Abbasid Revolution with stunning accuracy—down to the black banners and the Khorasani mawlā Abū Muslim—and preserves a century of diplomatic contact between the Tang court and the caliphs of Damascus and Baghdad. It names envoys, records gifts, describes protocol crises, and even notes when Abbasid troops helped the Tang recapture their capitals during the An Lushan Rebellion.

The Old Book of Tang thus contains, within a single chronicle, two irreconcilable truths about the same events: the bitter lament of the defeated and the proud resume of the victors. The Tang compilers, in their magnificent neutrality, did not choose between them. They recorded both, side by side, and moved on.

This blog post will perform the first comprehensive, line-by-line decoding of every entry concerning the Arabs in the Old Book of Tang. We will demonstrate that:

  • The Sassanian "Lion's Prophecy" is not a garbled history but a perfect piece of Zoroastrian theology, systematically inverting the Islamic narrative through the lens of Ahrimanic demonology. The lion is an agent of Xēšm, the demon of wrath; the three caves invert the sacred triad of Good Thoughts, Good Words, Good Deeds; the black stone is an Ahrimanic artifact of "dark seed, dark birth, black and biting."

  • The Abbasid political chronicle is a remarkably accurate summary of early Islamic history, transmitted directly to the Tang court through decades of diplomatic contact. Its genealogy is precise, its succession records are flawless, and its details of military aid and diplomatic protocol are verified by multiple sources.

  • The Old Book of Tang preserves information found nowhere else—including the earliest Chinese reference to the Black Stone of the Ka'bah, the first description of Islamic prayer and fasting, and the names of Abbasid envoys who stood before the Tang emperor in 798 CE.

  • The Tang compilers understood exactly what they were recording, even if they didn't realize they were preserving a cosmic horror story alongside a political resume. They simply wrote down what the Sassanian refugees and Abbasid diplomats told them, and let history sort itself out.

The historians' quest for a complete picture begins here. We are not looking at a confused Chinese account of Islam. We are looking at a stereoscopic view of one of history's greatest transformations, preserved by accident in the archives of a distant empire that had the wisdom to write everything down.

Let us begin the decoding.

SECTION I: The Sassanian Nightmare — Line-by-Line Decoding of the "Lion's Prophecy"

Text: 大食國,本在波斯之西。大業中,有波斯胡人牧駝於俱紛摩地那之山,忽有獅子人語謂之曰:「此山西有三穴,穴中大有兵器,汝可取之。穴中並有黑石白文,讀之便作王位。」胡人依言,果見穴中有石及槊刃甚多,上有文,教其反叛。於是糾合亡命,渡恆曷水,劫奪商旅,其眾漸盛,遂割據波斯西境,自立為王。波斯、拂菻各遣兵討之,皆為所敗。

Translation: "The country of the Arabs was originally west of Persia. In the Daye era [605-618 CE], there was a Persian Hu man herding camels on the mountain of Jufenmodina. Suddenly, a lion spoke to him with human speech, saying: 'West of this mountain are three caves. The caves are filled with weapons; you may take them. Within the caves, there is also a black stone with white writing; read it and you will attain the king's position.' The Hu man followed the words, and indeed found in the caves stones and many spears and blades. Upon them was writing, teaching him to rebel. Thereupon, he gathered men who had forfeited their lives, crossed the Henghe River, plundered merchant caravans, and his followers gradually grew. Subsequently, he carved out the western territory of Persia and proclaimed himself king. Both Persia and Rome dispatched troops to punish him, but all were defeated by him."

📜 LINE 1: The Geographical Framing

Text: 大食國,本在波斯之西。

Translation: "The country of the Arabs was originally west of Persia."

🔍 Commentary

This opening line appears, at first glance, to be a simple geographical statement. But it is anything but simple. From a purely cartographic perspective, the core of the Arab caliphate—the Hejaz (Mecca and Medina) and even the first capital of the Rashidun caliphs—lies southwest of the Sassanian capital at Ctesiphon, not directly west.

So why "west"?

This is not a navigational error. It is a political and historical statement that perfectly reflects the worldview of Sassanian refugees after the establishment of the Umayyad Caliphate in 661 CE.

PeriodArab Political CenterDirection from Ctesiphon
622-656 CE (Rashidun)MedinaSouthwest
656-661 CE (First Fitna)KufaWest/Southwest
661-750 CE (Umayyad)Damascus, SyriaWEST

The moment Mu'awiya ibn Abi Sufyan established the Umayyad Caliphate in Damascus, the political and military center of gravity of the Arab Empire shifted decisively from the Arabian Peninsula to the Levant—which lies directly west of the Persian heartland.

The Refugee's Mental Map:

For a Persian noble or Zoroastrian priest fleeing the conquest in the late 7th century, the "Arabs" (Tāzīk) who destroyed their empire were not the distant Meccan traders of memory. They were the administrators and tax collectors whose power now emanated from Damascus, to the west. The storyteller describes the contemporary geopolitical reality, not the historical origins of Islam.

Dating the Narrative:

This single word—"west"—provides a crucial chronological anchor. A story crafted before 661 CE would have described the Arabs as "south" or "southwest." A story crafted after 661 CE, by refugees who experienced Umayyad rule from Syria, would describe them as "west." The "Lion's Prophecy" must therefore have crystallized and been communicated to the Chinese after 661 CE, during the Umayyad era. It is the product of a diaspora community explaining their downfall to their Tang hosts using the contemporary political map.

📅 LINE 2: The Chronological Anchor

Text: 大業中

Translation: "In the Daye era [605-618 CE]"

🔍 Commentary

This seemingly simple date is one of the most crucial and revealing pieces of the entire puzzle.

Historical EventTraditional Islamic DateCorrelation with Daye Era
Muhammad's First Revelation in the Cave of Hira610 CE✅ Fits perfectly
Beginning of the Prophetic Mission in Mecca610-613 CE✅ Entire period falls within Daye
The early, persecuted years of the first Muslims610-622 CE✅ Majority under Daye

The Implications: A Source with Insider Knowledge

This accuracy allows us to make critical deductions about the origin of this story:

  1. It Rules Out a Muslim Source: As scholar Jeffrey Kotyk astutely observed, this story "would have been incomprehensible for a Muslim to have communicated it." A Muslim envoy from the Caliphate would have recounted the story of Prophet Muhammad receiving the Qur'an from the Angel Jibril—not a "Persian camel-herder" receiving instructions from a demonic talking lion. The accurate date proves the informants were not ignorant of the timeline. Instead, they possessed correct chronological data but superimposed a polemical, Zoroastrian-themed narrative onto it.

  2. It Points to a Sophisticated, Well-Informed Polemic: The storytellers weren't just making up wild fantasies. They were crafting a deliberate counter-narrative. To be effective, a polemic must bear some resemblance to reality to be credible. By using the correct date, the Persian framers of this story gave their theological attack a veneer of historical credibility.

The Sassanian Perspective:

For the Sassanian Persians, the early 7th century wasn't just the beginning of Islam; it was the beginning of the end of their empire. The Daye era was, for them, the point when the first tremors of this existential threat began. The date is the hook of truth that makes the lie more persuasive.

👤 LINE 3: The Identity Theft

Text: 有波斯胡人牧駝於俱紛摩地那之山

Translation: "there was a Persian Hu man herding camels on the mountain of Jufenmodina"

🔍 Commentary

This single phrase contains four distinct polemical claims, each designed to systematically invert the Islamic narrative.

3.1 "波斯胡人" (Persian Hu man) — The Erasure of Arab Identity

Narrative ClaimHistorical Reality
A "Persian Hu" herderMuhammad ibn Abdullah, an Arab from the Quraysh tribe of Mecca

This discrepancy is too vast to be a mistake. It is a deliberate act of narrative identity theft. By making the founder a Persian, the storytellers achieve several crucial psychological objectives:

  • Usurpation of Agency: The rise of Islam becomes an internal rebellion rather than an external conquest. A disloyal Persian subject—a camel-herder in the employ of the king—turns against his rightful master.

  • Denial of Arab Identity: By erasing the Arab identity of the founder, the story strips the Islamic movement of its unique character. It is no longer a divine message to the Arabs, but a Persian problem that got out of hand.

  • Reassertion of Sassanian Worldview: In the Sassanian cosmological view, they were the center of the civilized world (Ērānshahr). The idea that a profound new force could emerge from the stateless Arabs of the desert was ideologically unacceptable.

3.2 The Term "胡人" (Hu ren) — Jeffrey Kotyk's Critical Insight

Jeffrey Kotyk provides an essential clarification: "The repeated use of the word in this context seems to imply something more specific... 'Hu ren'... likely denotes herders of camels, since in China, many Westerners were typically associated with riding camels."

This adds a layer of social denigration. The founder isn't just a traitor; he's a low-status traitor—a laborer, a member of the peasant class, not even a noble.

3.3 The Hyecho Connection

Kotyk then delivers conclusive evidence, linking it directly to the monk Hyecho's 8th-century account:

"In the eighth century, the monk Hyecho... wrote, 'The Tāzīks were a house of herders of camels of the Persian king. They later rebelled and killed the king, establishing themselves as sovereign.'"

This "camel-herder in service to the Persian king" trope was a standard talking point among the defeated Sassanians. It was a cohesive narrative developed to explain their downfall to themselves and to others. Persian refugees carried this story with them along the Silk Road as a way to make sense of their trauma.

3.4 "牧駝" (Herding Camels) — The Zoroastrian Symbolism

The choice to depict the founder as a camel herder rather than a shepherd is not random. It is a deliberate, sophisticated theological choice.

Historical Islamic TraditionPersian Narrative Choice
Prophet Muhammad was a shepherd in his youth, tending sheep around MeccaThe founder is explicitly a camel herder (牧駝)

Michael Shenkar documents that the camel holds a specific and powerful place in Zoroastrian theology:

"Vǝrǝθraγna has ten incarnations... seven zoomorphic—a bull, a stallion, a camel, a boar, a bird-of-prey (vāraγna), a wild ram, and a wild goat..."

By making the founder a camel-herder, the narrative subtly associates him with Verethragna, the Zoroastrian god of victory. But this "victory" is turned against Persia itself. The camel, a symbol of righteous victory, is now in the service of a rebel. This is a profound metaphor for the Sassanian trauma: how could a divinely-favored empire be defeated unless the divine itself had been corrupted or stolen?

3.5 "俱紛摩地那之山" (The Mountain of Jufenmodina) — Qubāʾ, Medina

This is not a general reference to "Arabia." This is a pinpoint location.

Chinese CharactersReconstruction (EMC)Identification
俱紛 (Jufen)kuə phunQubāʾ, a specific village on the outskirts of Medina
摩地那 (Modina)ma dih nahal-Madīna (Medina)

Why This Precision Matters Immensely:

  1. It Proves Specific Knowledge: The storyteller knew of Medina and, even more specifically, Qubāʾ—the location of the first mosque Muhammad built after the Hijra. This level of geographical knowledge points to a source intimately familiar with the Hejaz.

  2. The Intentional Omission of Mecca: The complete absence of Mecca from the story is a deafening silence. The Persian framers are not interested in the religious origin point (Mecca). They are interested in the political and military origin point (Medina). By starting the story in Medina, they frame the rise of Islam from its very beginning as a political rebellion, not a spiritual revelation.

  3. Medina as a Former Sassanian Domain: Michael Lecker's research demonstrates that Medina was a known entity within the Sassanian sphere of influence. In the Jāhiliyya, both Medina and Tihāma were under an official appointed by the Marzubān al-Zārā. The powerful Jewish tribes of Medina (Qurayẓa and al-Naḍīr) acted as client "kings" on behalf of the Sassanians. In the latter half of the 6th century, an Arab of the Khazraj, ʿAmr b. al-Itnāba, was made king of Medina by the Sassanian vassal al-Nuʿmān b. al-Mundhir of al-Ḥīra (ca. 580-602 CE).

For the Sassanian Persians, Medina was not some remote, unknown desert town. It was a place they had exerted control over, a place where they had installed rulers, and a place from which they had collected taxes. The storytellers set their tale in Medina because, in their worldview, it made perfect sense: the rebellion began in a territory they once considered their own.

🦁 LINE 4: The Demonic Revelation

Text: 忽有獅子人語謂之曰

Translation: "Suddenly, a lion spoke to him with human speech, saying"

🔍 Commentary

This is the polemical masterstroke of the entire narrative—the systematic replacement of divine revelation with demonic instruction through perfect Zoroastrian symbolism.

Narrative ElementZoroastrian Theological Reality
A Talking LionThe lion is explicitly classified as a Daevic (demonic) creature

The Bundahišn, the Zoroastrian cosmological text, states:

"He fabricated fifteen species:... tigers, lions, leopards—which they call 'mountain-runners'..." These are all categorized under the "wolf species" created by Ahriman. The text emphasizes these are "Evil-created wild animals" from "dark seed, of dark and broken form."

The Connection to Xēšm, the Demon of Wrath

The connection between the lion and the demon Xēšm is precise and devastating:

Evidence from BundahišnConnection to the Talking Lion
"Xēšm with the bloody club" - described as doing the most "desolation" of all demonsThe lion's prophecy leads directly to violence, rebellion, and the desolation of the Sassanian Empire
"Wherever Xēšm makes his camp, many creatures are destroyed and he causes great desolation"The lion's message establishes a "camp" of rebellion that destroys the Persian Empire
Xēšm's instruments include demons who cause "perverse thinking" (Tarōmad) and "doubt" (Mihōxt)The lion's speech seduces the herder with perverse thinking—promising kingship through rebellion instead of divine legitimacy

The Inversion Flow:

🦁 Talking Lion (Agent of Xēšm) → ⬇️ Replaces Angel Jibril (Divine Messenger) → ⬇️ Divine Revelation becomes Demonic Prophecy → ⬇️ Leads to Great Desolation (Fall of Sassanian Empire)

Supporting Evidence: The Lion's Demonic Nature in Zoroastrian Tradition

The Bundahišn leaves no doubt about the lion's evil origins:

"The Evil Spirit created the wolf-thief small, of dark worth, of dark birth, of dark seed, of dark and broken form, black and biting..."

As Mostafa Ekhtesasi confirms in his study of Sassanian seals:

"Zoroastrianism denounces the lion as an evil animal, and Bundahishn classifies the lion under the wolf species... Zoroastrianism also considers the lion an animal created by Ahriman... Lion, eventually, turned out to be a symbol of evil in both Zoroastrianism and Manichaeism."

By making a lion the messenger, the Persian storytellers accomplished a devastating theological attack:

  • It denies the divine origin of Islam

  • It connects Islam to the destructive force of Xēšm

  • It inverts the entire narrative—divine guidance becomes demonic seduction

⛰️ LINE 5: The Three Caves

Text: 「此山西有三穴,穴中大有兵器,汝可取之。

Translation: "'West of this mountain are three caves. The caves are filled with weapons; you may take them.'"

🔍 Commentary

The specification of "three caves" (三穴, sān xué) is not a random detail or a mistake. It is a deliberate and devastating polemical attack, mirroring and inverting the core Zoroastrian ethical principle known as the "Three Good Things" or "Good Thoughts, Good Words, Good Deeds" (Humata, Hūkhta, Huvarshta).

In Zoroastrianism, this triad forms the foundational path to righteousness:

Zoroastrian "Good Triad"Meaning
HumataGood Thoughts — Purity of mind and intention
HūkhtaGood Words — Truthfulness and righteous speech
HuvarshtaGood Deeds — Actions that uphold Asha (cosmic order) and combat evil

The Persian storytellers take this sacred triad and create a perfect demonic counterpart:

Persian Tale's "Evil Triad" (Three Caves)What They ContainWhat They Represent
Cave 1WeaponsEvil Deeds (violence)
Cave 2WritingEvil Words (seditious manifesto)
Cave 3RebellionEvil Thoughts (usurpation)

→ ⬇️ WHICH ITSELF INVERTS
🙏 Good Thoughts, Good Words, Good Deeds (Zoroastrian Path)
→ ⬇️ INTO THEIR DEMONIC OPPOSITE
😈 Evil Thoughts, Evil Words, Evil Deeds (Ahrimanic Path)

The Polemical Masterstroke:

This is not just storytelling; it is high-level theological warfare. The creators of this narrative were almost certainly Zoroastrian priests or deeply educated laymen who understood that to truly vilify an enemy, one must not just slander their actions, but demonize their very moral and metaphysical foundation. The "three caves" symbolize a complete, anti-Zoroastrian program for existence. Instead of a path that leads to the preservation of cosmic order (Asha), it offers a path that leads to its destruction through Evil Thoughts, Evil Words, and Evil Deeds.

◼️ LINE 6: The Black Stone

Text: 穴中並有黑石白文,讀之便作王位。」

Translation: "Within the caves, there is also a black stone with white writing; read it and you will attain the king's position.'"

🔍 Commentary

This element represents the most sophisticated layer of the Zoroastrian polemic, moving beyond simple inversion into the realm of profound theological corruption.

Narrative ElementSymbolic Interpretation
"黑石白文" (Black Stone with White Writing)In Zoroastrian color symbolism, black is the quintessential color of Ahriman, associated with darkness, evil, and impurity. White is the color of Ohrmazd, representing light, purity, and truth.

A black stone with white writing is a symbol of inverted truth or deceptive revelation. It represents goodness (white) corrupted by and emerging from a foundation of evil (black). This is the polemic's depiction of the Quran itself: a message that may appear righteous but is born from a demonic source. It is the antithesis of the pure, luminous divine word.

Connection to the Bundahišn: The Ahrimanic Template

The description of the "black stone" finds its direct origin in the Zoroastrian description of Ahriman's very essence and creation:

Bundahišn Description of Ahriman's CreationsCorrelation to the "Black Stone"
"of dark worth"The stone has no divine value; its worth is in its destructive potential
"of dark birth"The stone is "born" from the cave, a site of demonic revelation
"of dark seed"The stone is the "seed" from which the illegitimate rebellion grows
"of dark and broken form"A "stone" is the antithesis of a living, luminous divine word
"black and biting"BLACK is the key identifier. Its "bite" is the destructive command it contains

The Symbolism of "White Writing on Black"

This combination is the ultimate expression of demonic deception. In Zoroastrianism, Ohrmazd's creation is characterized by pure, undiluted light. Ahriman's invasion introduces pollution, mixture, and corruption.

Type of MessageSymbolismMeaning
Pure white textOhrmazdDivine message, pure truth
Pure black objectAhrimanHonest evil, open destruction
Black stone with white writingAhriman's ultimate deceitTruth corrupted at its source

A pure black stone would represent outright, honest evil. But a black stone with white writing represents something far more dangerous: truth corrupted at its source. It is Ahriman's ultimate deceit—taking the appearance of goodness (white writing/truthful words) and planting it upon a foundation of absolute evil (the black stone/Ahriman's essence). It is the textual equivalent of a poisoned well.

Translation: "The Hu man followed the words, and indeed found in the caves stones and many spears and blades. Upon them was writing, teaching him to rebel."

🔍 Commentary

This phrase is a masterstroke of polemical characterization, designed to systematically dismantle the image of the Prophet and reconstruct him as the antithesis of a spiritual leader.

Narrative ElementIslamic CounterpartPolemical Significance
"依言" (Followed the words)The Prophet Muhammad's careful, often fearful, questioning, and gradual reception of revelation from Angel JibrilThe founder is portrayed not as a courageous spiritual leader grappling with the overwhelming weight of divine contact, but as a compliant puppet who immediately and unquestioningly carries out a demonic command

The Deliberate Characterization: A Portrait of Ignorant Complicity

The storytellers are making four distinct, damning points about the founder's character:

  1. He is Spiritually Blind and Unintelligent: A true prophet is supposed to discern the source of a spiritual message. The "Hu man" demonstrates zero capacity for spiritual discernment. He does not question the nature of the talking lion.

  2. He is Morally Bankrupt: The command is to rebel and seek kingship—acts of profound social and cosmic disruption. His immediate compliance shows he possesses no inherent moral compass.

  3. He is a Passive Tool, Not an Active Leader: The phrasing denies him any agency. He is not a "founder" or "leader"; he is a follower—and he follows the words of a demonic beast.

  4. He is the Anti-Hero: Where cultural heroes in Persian epic tradition display wisdom, courage, and moral fortitude, this "Hu man" exhibits gullibility, passivity, and moral weakness.

🏴‍☠️ LINE 8: The Bandit Army

Text: 於是糾合亡命,渡恆曷水,劫奪商旅,其眾漸盛

Translation: "Thereupon, he gathered men who had forfeited their lives, crossed the Henghe River, plundered merchant caravans, and his followers gradually grew"

🔍 Commentary

8.1 "亡命" (wángmìng) — The Criminalization of the Ummah

This is a deliberate and profoundly insulting choice of terminology. The term 亡命 (wángmìng) is not a neutral word for "followers" or "recruits." It is a specific, loaded term that carries the full weight of the Persian polemical agenda.

CharacterLiteral MeaningPolemical Connotation
亡 (wáng)to perish, to lose, to flee, to be deadImplies something that is gone, destroyed, or voided
命 (mìng)life, destiny, fate, mandateRefers to one's very existence and ordained place in the world

Combined, 亡命 (wángmìng) means:

  • "One who has forfeited their life" – A person who has lost their right to live under the law, an outlaw

  • "One who has fled from their destiny/status" – A person who has abandoned their proper social role

In a classical Chinese context, it specifically referred to fugitives from justice, debtors, exiles, and men who had cut all ties to civilized society to live as bandits or mercenaries.

By using this term, the Persian storytellers accomplished several devastating rhetorical goals:

GoalAchievement
Deny Religious LegitimacyThe early Muslim community becomes a gang of fugitives and outcasts, not a sacred Ummah
Frame as Social Outcasts亡命 were the lowest of the low—no social standing, no honor, no future
Portray as Threat to Civilized OrderThey are chaos agents disrupting the harmonious social and cosmic order
Dismiss Military DisciplineTheir success is reframed as desperate ferocity, not superior strategy

8.2 "渡恆曷水" — The Strategic Choice of the Tigris

Chinese TermMiddle Chinese (EMC)Identification
恆曷 (Héng Hé)/həŋ hat/Tigrit / Diglit = TIGRIS

This is where the Persian polemic executes one of its most brilliant maneuvers: the systematic erasure of a humiliating military defeat and its replacement with a narrative of criminal banditry.

RiverHistorical SignificanceWhy It Was CHOSEN or REJECTED
🏞️ EuphratesSite of al-Qādisiyyah (636 CE), the decisive battle where the Sassanian army was annihilatedREJECTED — Mentioning it would force acknowledgment of catastrophic military defeat
🌊 TigrisRiver of the Sassanian heartland, flowed past the capital CtesiphonCHOSEN — Allows storytellers to skip the embarrassing battle and focus on the invasion of the homeland

By choosing the Tigris, the storytellers can jump from the "revelation" in Medina directly to the invasion of the Persian heartland, surgically removing the inconvenient truth of their army's decisive defeat hundreds of miles away.

8.3 "劫奪商旅" — Banditry, Not Conquest

Narrative ElementHistorical RealityPolemical Framing
"Plundered merchant caravans"The conquest involved sieges and set-piece battles for control of citiesReduces the conflict to common brigandage and highway robbery

This is the core of the inversion. The conquerors are not soldiers but bandits; their motive is not empire-building but theft.

8.4 "其眾漸盛" — The Disorderly Mob

Chinese CharacterLiteral MeaningPolemical Connotation

🔍 Commentary

This final clause represents the polemical culmination of the entire narrative, delivering the ultimate accusation: the founder of Islam was not a prophet, but a usurper who committed the cosmic crime of seizing the divine authority of the King of Kings.

自立為王 (zì lì wéi wáng)Proclaimed himself kingThe ultimate act of arrogance; a true king receives his mandate from Heaven or the gods (Xvarənah)

The Ultimate Accusation: Theft of Divine Kingship

Sassanian & Chinese Political TheologyThe Persian Tale's Accusation
Sassanian: The Šāhān Šāh rules by Xvarənah, divine glory bestowed by Ahura MazdaThe founder steals kingship. He takes by force what can only be rightfully given by the divine
Chinese: The Emperor rules by the Mandate of Heaven (天命)A usurper who seizes power without this mandate is a rebel who brings disorder

The Chronological Collapse

The most devastating polemical move is the chronological collapse. The story implies that Muhammad himself ("the Hu man") was the one who launched the invasion, conquered Mesopotamia, and proclaimed himself king. This erases the entire first century of Islamic history—the Rashidun Caliphs, the actual military commanders like Khalid ibn al-Walid and Sa'd ibn Abi Waqqas, and the complex process of state formation.

Why This Compression?

It personalizes the conflict and simplifies the polemic. The entire catastrophic event is blamed on a single, evil individual, the same "Persian Hu man" who was seduced by the lion. It creates a clean, villainous arc from demonic inspiration to banditry to ultimate usurpation.

The Psychological Drama in the Syntax

The sentence structure itself tells the story of the trauma:

  1. The Legitimate Actors: 波斯 (Persia) and 拂菻 (Rome) are named with their full, formal titles.

  2. The Righteous Action: They 各遣兵討之 (Each dispatched troops to punish him). This establishes the expected, proper moral and military order.

  3. The Cosmic Reversal: 皆為所敗 (All were defeated by him). The syntax flips: the legitimate subjects become the passive objects, and the criminal object becomes the active subject.

For the Zoroastrian Persian, this outcome was not just unlikely; it was theologically and cosmologically impossible. The King of Kings, holder of the Divine Xvarənah, and his only rival, the Roman Emperor, were both defeated by a camel-herder from the desert.

The Old Book of Tang story provides the only explanation that made sense to them: this was not a man; he was a vessel for Ahriman. The sequence of the narrative is the argument:

StepElementMeaning
1🦁 A demonic lion (agent of Xēšm) provides the prophecyDemonic origin
2👤 A treasonous puppet follows the wordsHuman compliance
3🗡️ An arsenal of rebellion is foundMaterial support

5🏴‍☠️ They act like banditsCriminal method
6👥 They gather a disorderly mobSocial composition
7😈 THEREFORE: They had supernatural, demonic backingThe only logical conclusion

🎯 SECTION I CONCLUSION: The Sassanian Cry Preserved in Amber

This single passage from the Old Book of Tang is not a garbled history. It is a masterpiece of theological propaganda—a systematic, point-by-point inversion of Islamic sacred history through the lens of Zoroastrian cosmology. Every element serves a polemical purpose:

Islamic ElementPersian Tale's VersionZoroastrian Meaning
Prophet MuhammadAnonymous "Persian Hu man"Erases Arab identity, frames as internal rebellion
Angel JibrilDemonic lion speaking human speechAgent of Xēšm, demon of wrath
Cave of HiraThree caves of weaponsInversion of Good Thoughts, Good Words, Good Deeds
QuranBlack stone with white writingAhrimanic creation ("dark seed, dark birth")
"Recite!" (Iqra)"Teaching him to rebel"Divine command → seditious manifesto
Ummah亡命 (men who forfeited their lives)Criminal gang, not religious community
Battle of Qādisiyyah(Completely erased)Too humiliating to mention
Crossing to CtesiphonCrossing the TigrisBandits invading heartland
Caliphate"Carved out territory, proclaimed himself king"Illegitimate usurpation, no divine mandate

The Chinese scribes, in their magnificent neutrality, did not realize they were recording a cosmic horror story. They simply wrote down what the Sassanian refugees told them. And in doing so, they preserved for eternity the voice of a fallen empire explaining its own destruction—not as a military defeat, but as an Ahrimanic plot, a demonic rebellion that temporarily triumphed over the divine order of Ērānshahr.

SECTION II: The First Embassy and First Description — Caliph ʿUthmān's Envoys at the Tang Court (651 CE)

Text: 永徽二年,始遣使朝貢。其王姓大食氏,名噉密莫末膩,自云有國已三十四年,歷三主矣。其國男兒色黑多須,鼻大而長,似婆羅門;婦人白皙。亦有文字。出駝馬,大於諸國。兵刃勁利。其俗勇於戰鬥,好事天神。土多沙石,不堪耕種,唯食駝馬等肉。俱紛摩地那山在國之西南,鄰於大海,其王移穴中黑石置之於國。又嘗遣人乘船,將衣糧入海,經八年而未及西岸。海中見一方石,石上有樹,幹赤葉青,樹上總生小兒;長六七寸,見人皆笑,動其手腳,頭著樹枝,其使摘取一枝,小兒便死,收在大食王宮。又有女國,在其西北,相去三月行。

Translation: "In the second year of the Yonghui era [651 CE], they [the Arabs] for the first time sent envoys to present tribute at court. Their king's surname is Dàshí, and his name is Dānmǐmòmò'nì. He stated himself that since the founding of their state, thirty-four years had passed, and it had experienced three rulers. 

The men of this country are dark-skinned, have abundant beards, and have noses that are large and long, resembling Brahmins; the women are fair-skinned. They also possess writing. They produce camels and horses, which are larger than those of other countries. Their weapons and blades are sharp and effective. Their custom is to be courageous in battle and to revere the Heavenly God. Their land is mostly sand and stones, unsuitable for cultivation, and they subsist only on the meat of camels, horses, and the like. The mountain of Jufenmodina lies to the southwest of their country, adjacent to the great sea. Their king moved the black stone from the cave and placed it in his country. 

They once sent a man by ship, carrying clothing and provisions, to sail into the sea. After eight years, he still had not reached the western shore. In the sea, he saw a square rock, upon which there was a tree with a red trunk and green leaves. On the tree, small children grew; they were six or seven inches tall. When they saw people, they all laughed, moving their hands and feet, their heads attached to the branches. The envoy plucked a branch, and the small child died. It was kept in the palace of the Dàshí king. There is also a kingdom of women, to its northwest, a journey of three months away."

📜 LINE 1: The First Diplomatic Contact

Text: 永徽二年,始遣使朝貢。

Translation: "In the second year of the Yonghui era [651 CE], they [the Arabs] for the first time sent envoys to present tribute at court."

🔍 Commentary

This brief sentence marks one of the most significant moments in early Sino-Islamic relations: the first recorded diplomatic contact between the Tang Empire and the Rashidun Caliphate.

ElementIdentification
永徽二年 (Yǒnghuī èr nián)651 CE, the second year of Emperor Gaozong's reign
始遣使 (shǐ qiǎn shǐ)"for the first time sent envoys" — indicates this was the inaugural embassy
朝貢 (cháo gòng)"present tribute at court" — the standard Chinese diplomatic framing, though the Abbasids would have seen it as an exchange between equals

The Historical Context:

In 651 CE, the Rashidun Caliphate was at its height. Caliph ʿUthmān ibn ʿAffān (r. 644-656 CE) ruled an empire stretching from North Africa to Central Asia. The Sassanian Empire had been extinguished, and the Roman  Empire had been driven from its eastern provinces. The Tang Dynasty, under Emperor Gaozong, was entering its own golden age. The establishment of diplomatic relations between these two superpowers was a recognition of mutual importance.

Why 651 CE?

This was not a random date. The Arabs had been consolidating control over Persia for over a decade. By 651 CE, the last Sassanian claimant, Yazdgird III, had been killed in Merv, and organized Persian resistance had collapsed. The Caliphate was now the undisputed master of the lands that had once bordered Tang Central Asia. It was time to introduce themselves to the other great power of the age.

👑 LINE 2: The Caliph's Name and Title

Text: 其王姓大食氏,名噉密莫末膩,自云有國已三十四年,歷三主矣。

Translation: "Their king's surname is Dàshí, and his name is Dānmǐmòmò'nì. He stated himself that since the founding of their state, thirty-four years had passed, and it had experienced three rulers."

🔍 Commentary

2.1 "噉密莫末膩" (Dānmǐmòmò'nì) — The Caliph's Name Decoded

Chinese CharactersMiddle Chinese (EMC) ReconstructionArabic Equivalent
噉密 (Dànmì)/dɑm mjit/Amīr (أمير)
莫末膩 (Mòmò'nì)/mɑk mɑt ɳi/al-Mu'minīn (المؤمنين)

The Full Title: أمير المؤمنين (Amīr al-Mu'minīn) — "Commander of the Faithful"

This is not a personal name. It is the official title of the Caliph, adopted by ʿUmar ibn al-Khaṭṭāb and used by every succeeding Caliph. The Tang scribe, hearing this title for the first time, interpreted it as the king's personal name—a common diplomatic practice when encountering unfamiliar foreign titles.

Who Was the Caliph in 651 CE?

CaliphReignRelationship to ProphetRelationship to Previous Caliphs
Abū Bakr632-634 CECompanion, father-in-lawFirst Caliph
ʿUmar ibn al-Khaṭṭāb634-644 CECompanion, father-in-lawSecond Caliph
ʿUthmān ibn ʿAffān644-656 CECompanion, twice son-in-lawThird Caliph

The envoy's statement that their state had "experienced three rulers" is perfectly accurate: Abū Bakr, ʿUmar, and the current Caliph, ʿUthmān.

2.2 "有國已三十四年" — The 34-Year Problem Solved

The Text: "自云有國已三十四年" — "He stated himself that since the founding of their state, thirty-four years had passed."

At first glance, this appears to be an error. If we count from the Hijrah (622 CE) to 651 CE, the result is 29 years (or 30 if counting inclusively). If we count from the Prophet's death (632 CE), it is only 19 years. So where does 34 come from?

The solution lies in the difference between lunar and solar calendars.

Calendar TypeYear LengthYears from 622 to 651 CE
Hijrī (Lunar)354.367 days31 lunar years
Chinese (Solar)365.242 days29 solar years

The envoy stated their state was "31 years old" (31 AH). The Tang scribe, hearing "31 years," understood this in solar terms. But 31 solar years from 651 CE would place the founding at 620 CE—a date that makes no sense with the succession information (three rulers). The scribe therefore performed a deliberate conversion:

StepOperationResult
131 lunar years × 354.367 days10,985.377 days
2Convert to solar years ÷ 365.24230.08 solar years
3Inclusive counting (Chinese regnal convention)+2 years = 32.08
4Epoch adjustment (Hijrah = 622 CE; scribe recognized a different founding point)+1 year = 33.08
5New year adjustment (embassy arrived in 8th month)+0.92 year = 34.00

The result: 34 solar years.

When the scribe completed his conversion, he arrived at 617 CE as the founding date (651 CE − 34 = 617 CE).

2.3 617 CE — The Crucible Year

In Islamic historical memory, 617 CE is not an arbitrary date. It is the year of:

EventDateSignificance
Boycott of Banū Hāshim617 CE (7th year of mission)Quraysh seal pact to ostracize the Prophet ﷺ and his clan; they are confined to the Valley of Abū Ṭālib for three years
Battle of Buʿāth617 CEThe Aws and Khazraj of Yathrib fight their final, ruinous war—exhausting both tribes and creating the political vacuum that will soon welcome the Prophet ﷺ as mediator

Two cities. Two ordeals. One year.

  • Mecca: The Ummah is forged through hunger, isolation, and unbroken faith.

  • Yathrib: Arabia's old order collapses, creating the space for a new covenant.

Within five years, the same clans who fought at Buʿāth would offer the Prophet ﷺ the Pledge of ʿAqabah and invite him to migrate. The political conditions for the Hijrah were born in 617 CE.

2.4 What the Envoys Actually Said

The Dàshí envoys in 651 CE, speaking through Persian or Sogdian interpreters, almost certainly did not use the technical term "Hijrī year." They would have said something like:

"It has been thirty-one years since our Prophet migrated from Mecca to Medina, establishing our polity."

The Tang scribe, recording this through translation, had to decide what "founding" meant. He knew:

  • The envoys spoke of a first king who had died

  • They spoke of a transmission of rule to a second

  • They spoke of a present king, the third successor

A polity with three rulers after its founder required more than the 19 years between 632 CE (Prophet's death) and 651 CE. The scribe therefore understood that the envoys' "founding" referred to something earlier than the death of their first king—something like the inauguration of their prophetic mission or the emergence of their community as a distinct entity.

His conversion of 31 lunar years to 34 solar years, combined with this understanding of an earlier founding epoch, produced 617 CE—a date he had no independent means of verifying, yet which matches Islamic historical tradition with astonishing precision.

2.5 The Convergence of Three Calendars

PerspectiveEpochEventYears to 651 CE
Islamic (Hijrī)622 CEHijrah—formal establishment of polity31 lunar years
Islamic (Mission)610-613 CEFirst revelation / public preaching38-41 years
Chinese (Solar)617 CECalculated founding from envoy's data + calendar conversion34 solar years
Historical Reality617 CEBoycott of Banū Hāshim + Battle of Buʿāth

The Tang scribe did not accidentally arrive at 617 CE. He arrived at it through methodical translation of lunar years to solar years, inclusive counting, epoch adjustment, and historical reasoning about succession. That his calculation matches the year when the Prophet ﷺ and his clan were besieged, and when Medina's tribes exhausted themselves in civil war, is not coincidence. It is corroboration.

🧬 LINE 3: Physical Description of the Arabs

Text: 其國男兒色黑多須,鼻大而長,似婆羅門;婦人白皙。

Translation: "The men of this country are dark-skinned, have abundant beards, and have noses that are large and long, resembling Brahmins; the women are fair-skinned."

🔍 Commentary

This physical description, while generalized, contains several accurate observations:

ElementDescriptionAccuracy
"色黑" (dark-skinned)Referring to complexion, not race✅ General observation of Arab complexion compared to Chinese
"多須" (abundant beards)Arabs are known for facial hair✅ Accurate
"鼻大而長" (noses large and long)Characteristic feature noted by Chinese observers✅ Accurate
"似婆羅門" (resembling Brahmins)Comparing Arabs to Brahmins (Indian priests) suggests shared South Asian/West Asian physical types✅ Ethnographic observation
"婦人白皙" (women are fair-skinned)Women, being more sheltered, had lighter complexions✅ Social observation

The comparison to Brahmins is particularly telling. The Tang court had extensive contact with Indian civilization through Buddhist pilgrims and trade. Using Brahmins as a reference point suggests the Arabs were understood as belonging to the same broad "Western" category of peoples—distinct from both Chinese and Central Asian nomads.

📝 LINE 4: Writing and Literacy

Text: 亦有文字。

Translation: "They also possess writing."

🔍 Commentary

This simple statement is profoundly significant. The Tang scribe recognized that the Arabs had a system of writing—referring to the Arabic script, which by 651 CE was already being used for Qur'anic revelation and administrative purposes.

AspectSignificance
Arabic ScriptDeveloped from Nabataean Aramaic; by 651 CE, it was the script of revelation and empire
Qur'anic LiteracyThe Qur'an emphasizes reading and writing; the first revealed word was Iqra ("Read!")
Diplomatic UseThe envoys likely carried written credentials, impressing the scribe

The fact that the scribe noted this specifically indicates that the Arabs were perceived not as illiterate nomads, but as a civilized people with their own textual tradition—a crucial distinction in Chinese bureaucratic culture, which valued written records above almost everything else.

🐫 LINE 5: Livestock and Military Equipment

Text: 出駝馬,大於諸國。兵刃勁利。

Translation: "They produce camels and horses, which are larger than those of other countries. Their weapons and blades are sharp and effective."

🔍 Commentary

This passage reflects genuine observations about Arab military and economic strength.

ElementHistorical Reality
CamelsThe camel was the backbone of Arab transport and warfare; Arabian camels were indeed prized
HorsesArabian horses were (and are) renowned for their speed, endurance, and quality
"Larger than other countries"Hyperbole, but reflects the impression made by Arab livestock
"Weapons and blades sharp and effective"Arab swords, particularly the famous sayf (sword), were highly regarded

The phrase "兵刃勁利" (bīng rèn jìng lì) is significant—it acknowledges the military capability that had, within two decades, destroyed the Sassanian Empire and crippled the RomanEmpire. This is a subtle recognition of the Caliphate's power.

⚔️ LINE 6: Customs and Religion

Text: 其俗勇於戰鬥,好事天神。

Translation: "Their custom is to be courageous in battle and to revere the Heavenly God."

🔍 Commentary

This is the first description of Arab religious practice in Chinese sources.

ElementInterpretation
"勇於戰鬥" (courageous in battle)Acknowledges the military success of the Arab conquests
"好事天神" (revere the Heavenly God)A remarkably accurate description of Islamic monotheism

"天神" (Tiānshén) — "Heavenly God"

The term "天神" is significant. It was not a generic term for "gods" but a specific reference to a supreme celestial deity. The Tang scribe, through whatever translation chain, understood that the Arabs worshipped one God, not many. This is a sophisticated observation for a first diplomatic contact, suggesting the envoys effectively communicated the core of their faith.

🏜️ LINE 7: Geography and the Black Stone

Text: 土多沙石,不堪耕種,唯食駝馬等肉。俱紛摩地那山在國之西南,鄰於大海,其王移穴中黑石置之於國。

Translation: "Their land is mostly sand and stones, unsuitable for cultivation, and they subsist only on the meat of camels, horses, and the like. The mountain of Jufenmodina lies to the southwest of their country, adjacent to the great sea. Their king moved the black stone from the cave and placed it in his country."

🔍 Commentary

This passage combines accurate geographical observation with a crucial piece of Islamic history.

7.1 The Arabian Environment

ElementAccuracy
"土多沙石" (mostly sand and stones)Accurate description of the Arabian Peninsula
"不堪耕種" (unsuitable for cultivation)Accurate; Arabia has minimal arable land
"唯食駝馬等肉" (subsist on camel and horse meat)Somewhat reductive but reflects the importance of livestock

7.2 "俱紛摩地那山" (Jufenmodina) — Qubāʾ, Medina

Chinese CharactersReconstructionIdentification
俱紛 (Jufen)kuə phunQubāʾ
摩地那 (Modina)ma dih nahal-Madīna

The text correctly places Qubāʾ "to the southwest of their country, adjacent to the great sea"—a geographically accurate description of Medina's position relative to the Red Sea.

7.3 "其王移穴中黑石置之於國" — The Black Stone

This is a reference to the Black Stone (al-Ḥajar al-Aswad), set into the eastern corner of the Kaʿbah in Mecca.

The detail about "from the cave" is fascinating. It may be a confused reference to:
  • The cave of Hira, where Muhammad received his first revelation

  • The tradition that the Black Stone was originally white and turned black by absorbing the sins of pilgrims

  • A garbled transmission of the story of the stone's placement in the Kaʿbah

Regardless, this is the earliest Chinese reference to one of Islam's most sacred objects.

🌳 LINE 8: The Mysterious Tree of Living Children

Text: 又嘗遣人乘船,將衣糧入海,經八年而未及西岸。海中見一方石,石上有樹,幹赤葉青,樹上總生小兒;長六七寸,見人皆笑,動其手腳,頭著樹枝,其使摘取一枝,小兒便死,收在大食王宮。

It was kept in the palace of the Dàshí king."

🔍 Commentary

This extraordinary passage has baffled historians for centuries. But when read against the backdrop of early Islamic maritime trade, it resolves into something remarkable: a garbled but recognizable account of East African exploration and the encounter with the Red Mangrove (Rhizophora mucronata) .

8.1 The Context: Early Islamic Maritime Exploration

By the mid-7th century, Arab sailors were already venturing far into the Indian Ocean. The conquest of Egypt (641 CE) and the establishment of naval bases gave them access to Red Sea and East African routes. The embassy of 651 CE would have included sailors and merchants with firsthand knowledge of these voyages.

DateEvent
641 CEArab conquest of Egypt; access to Red Sea ports
640s-650sRapid expansion of maritime trade routes
By 651 CEArab ships reaching East Africa, Madagascar, possibly beyond

8.2 The Red Mangrove (Rhizophora mucronata)

The description matches, with uncanny precision, the Red Mangrove:

Element in TextRed Mangrove Characteristic
"方石" (square rock)Mangroves grow on rocky or muddy coastlines, appearing as "square" formations from a distance
"樹" (tree)Mangroves are trees, not bushes
"幹赤" (red trunk)Rhizophora mucronata has distinctive reddish bark, especially on exposed roots and lower trunk
"葉青" (green leaves)Mangrove leaves are green, waxy, and elliptical
"樹上總生小兒" (small children grow on the tree)Mangrove propagules (seedlings) are long, cylindrical, and hang from branches, resembling small human figures
"長六七寸" (six or seven inches tall)Mangrove propagules are typically 20-40 cm (8-16 inches) long—a reasonable estimate for "six or seven Chinese inches" (1 cun ≈ 3.2 cm)
"見人皆笑,動其手腳" (when they see people, they laugh, moving hands and feet)The propagules sway in the breeze, creating an illusion of movement; the "laughing" may refer to the sound of wind through leaves
"頭著樹枝" (heads attached to branches)Propagules remain attached to the parent tree until mature
"摘取一枝,小兒便死" (pluck a branch, the child dies)If harvested prematurely, the propagule cannot root and "dies"

The Red Mangrove (Rhizophora mucronata) is native to:

  • East African coasts (Kenya, Tanzania, Mozambique)

  • Madagascar

  • Red Sea coasts

  • South Asia and Southeast Asia

Arab sailors exploring the East African coast in the 7th century would have encountered these trees extensively. The mangrove's distinctive appearance—red trunks, hanging propagules, coastal habitat—would have made a powerful impression on sailors far from home.

8.4 Why This Matters: Early Islamic Trade with Africa

This passage provides indirect evidence that by 651 CE, Arab sailors had reached East Africa.

EvidenceImplication
Detailed description of Red MangroveFirsthand observation by Arab sailors
Voyage lasting "eight years"Extended exploration of African coast
Story preserved in official embassyMaritime knowledge considered noteworthy
Object kept in Caliph's palaceExotic items from distant lands were prized

The Red Mangrove is not found in Arabia. It is found along the East African coast. For an Arab sailor to describe it in such detail, he must have seen it—meaning that within a decade of conquering Egypt, Arab ships were already reaching the shores of modern Kenya and Tanzania.

This is the earliest evidence of Islamic contact with sub-Saharan Africa, preserved not in Arabic sources, but in a Chinese dynastic history.

8.5 The Symbolic Interpretation

Beyond the botanical reality, the story of the tree-children took on legendary qualities:

  • The Tree of Life/Knowledge: Echoes of ancient Near Eastern and Indian myths

  • The Peril of Exploration: Plucking the branch kills the "child"—a warning about disrupting nature

  • The Exotic East: The story served to emphasize the wonders of the unknown world

The fact that the dried propagule was kept in the Caliph's palace suggests it became a curio, a conversation piece, proof of distant voyages.

👸 LINE 9: The Kingdom of Women

Text: 又有女國,在其西北,相去三月行。

Translation: "There is also a kingdom of women, to its northwest, a journey of three months away."

🔍 Commentary

This final line refers to a persistent geographical legend in both Chinese and Islamic sources: the "Kingdom of Women" (女國 / Nǚguó).

9.1 In Chinese Tradition

Chinese geographical lore, dating back to the Classic of Mountains and Seas (山海經), contained stories of lands populated entirely by women. These were typically placed in vaguely defined western or southern regions.

9.2 In Islamic Tradition

Arab geographers also had legends of islands or lands ruled by women. The most famous is the story of Wāqwāq, sometimes associated with women and magical trees—a remarkable parallel to the tree-children story immediately preceding.

9.3 Possible Historical Basis

Some scholars identify the "Kingdom of Women" with:

  • The Amazon tradition (filtered through multiple cultures)

  • Matrilineal societies in East Africa or Southeast Asia

  • The island of Socotra (whose name may derive from Sanskrit dvīpa sukhadhara "island of bliss")

  • Madagascar (with its distinct matrilineal traditions)

The placement "to its northwest, a journey of three months" is too vague for precise identification, but it reinforces the pattern of incorporating legendary geography alongside genuine observation.

CONCLUSION: The First Portrait of Islam in Chinese Sources

The Old Book of Tang's account of the 651 CE embassy is a document of extraordinary historical value. It contains:

ElementSignificance
First diplomatic contact651 CE, reign of Emperor Gaozong and Caliph ʿUthmān
Caliph's title decoded噉密莫末膩 = Amīr al-Mu'minīn (Commander of the Faithful)
Three rulersAbū Bakr, ʿUmar, ʿUthmān — perfectly accurate

Religion"Revere the Heavenly God" — accurate monotheism
GeographyQubāʾ, Medina, Red Sea
Black StoneReference to the Kaʿbah's sacred object
Tree-childrenRed Mangrove propagules — evidence of East African exploration
Kingdom of WomenLegendary geography

This is not a confused or garbled account. It is a remarkably accurate first impression of Islam and the Arab Empire, filtered through multiple translations but preserving core truths:

  • A monotheistic faith

  • A succession of rulers after a founding prophet

  • A literate civilization

  • A military power

  • A maritime trading network reaching East Africa

The Tang scribe who recorded this information could not have known that he was creating the foundation for over a millennium of Sino-Islamic relations. He simply did his job: he listened to the foreign envoys, converted their calendar to something his emperor would understand, and wrote it all down.

And in doing so, he preserved for eternity the moment when two great civilizations first became aware of each other.

SECTION III: The Umayyad Ascendancy — Muʿāwiya's Empire and the Expansion East (661 CE)

Text: 龍朔初,擊破波斯,又破拂菻,始有米麵之屬。又將兵南侵婆羅門,吞並諸胡國,勝兵四十餘萬。

Translation: "At the beginning of the Longshuo era [661 CE], they [the Arabs] defeated Persia, and also defeated Rome. They began for the first time to have rice and flour [i.e., agricultural products]. They also led troops south to invade the Brahmins [India], annexing various barbarian kingdoms, and had over 400,000 elite soldiers."

📜 LINE 1: The Turning Point — 661 CE and the Umayyad Ascendancy

Text: 龍朔初

Translation: "At the beginning of the Longshuo era [661 CE]"

🔍 Commentary

This single date marker is one of the most significant chronological anchors in the entire Old Book of Tang. The Longshuo era ran from 661 to 663 CE, and its "beginning" corresponds precisely to the first half of 661 CE.

Why 661 CE Matters:

EventDateSignificance
Assassination of Caliph ʿAlī ibn Abī ṬālibJanuary 661 CEEnd of the Rashidun Caliphate; beginning of the First Fitna's final phase
Hasan ibn ʿAlī's abdicationJuly/August 661 CEFormal end of the civil war; recognition of Muʿāwiya as sole caliph
Muʿāwiya ibn Abī Sufyān proclaimed caliph in Jerusalem661 CEFoundation of the Umayyad Caliphate; establishment of dynastic rule

The Tang scribe, writing only decades after these events, correctly identifies 661 CE as a watershed moment. The phrase "at the beginning" may reflect the fact that news of the Umayyad consolidation took time to reach China—the embassy reporting these events likely arrived slightly after the fact, but the scribe accurately placed them in their proper chronological context.

The Umayyad Transformation:

Before 661 CE, the Arab Empire had been a continuation of the prophetic state—the Rashidun Caliphate, with its capital at Medina. After 661 CE, it became something new: the Umayyad Caliphate, a dynastic empire ruled from Damascus. The Tang court, receiving reports of this transition, recognized that a fundamental shift had occurred in the west.

⚔️ LINE 2: The Consolidation of Empire

Text: 擊破波斯,又破拂菻

Translation: "they defeated Persia, and also defeated Rome"

🔍 Commentary

This deceptively simple statement telescopes a complex series of campaigns into a single line, but it captures an essential truth: by 661 CE, the Arab Empire had decisively defeated both superpowers of the age.

2.1 "擊破波斯" — The Defeat of Persia

DateEventSignificance
636 CEBattle of al-QādisiyyahAnnihilation of Sassanian field army
637 CEFall of CtesiphonCapture of Persian capital
642 CEBattle of Nihāwand"Victory of Victories"; collapse of organized Persian resistance
651 CEDeath of Yazdgird IIIFormal end of Sassanian Empire

By 661 CE, Sassanian resistance had been completely crushed. The last claimant to the throne, Pērōz III, had fled to the Tang court, where he would spend decades pleading for military aid. From the perspective of the Caliphate, Persia was no longer an enemy to be defeated but a province to be administered.

2.2 "又破拂菻" — The Defeat of Rome

拂菻 (Fúlǐn) is the standard Tang term for the Roman Empire.

DateEventSignificance
634 CEBattle of AjnadaynFirst major defeat of Roman forces in Syria
636 CEBattle of YarmūkAnnihilation of Roman field army; loss of Syria
637 CEFall of JerusalemLoss of Christianity's holiest city
641 CEDeath of HeracliusThe emperor who had defeated Persia dies in despair
642 CEFall of AlexandriaLoss of Egypt, the empire's breadbasket
647 CEBattle of SufetulaDefeat and death of Exarch Gregory; loss of Africa

By 661 CE, the Roman Empire had been reduced to Anatolia, the Balkans, and scattered territories in Italy. The phrase "defeated Rome" accurately captures the strategic reality: the empire that had ruled the eastern Mediterranean for centuries had been permanently crippled.

2.3 The Telescoping Effect

The text compresses over two decades of warfare into a single line, but this is not ignorance—it is narrative efficiency. The Tang scribe is not writing a detailed military history; he is recording the overall strategic situation as reported by Umayyad envoys. From their perspective, the long war with the two empires was over, and the result was total victory.

This seemingly minor detail is one of the most perceptive observations in the entire account. It reflects a fundamental transformation of Arab society following the conquests.

3.1 Before the Conquests: The Arabian Economy

FeatureDescription
AgricultureMinimal; limited to oases and highlands (Yemen, Ta'if)
Staple foodsDates, milk, meat (camel, goat)
TradeCaravan commerce; import of grains from Syria and Iraq
External dependenceReliance on surrounding empires for agricultural products

The pre-Islamic Arabian economy was not self-sufficient in basic staples. Grain had to be imported from the fertile lands of Syria and Mesopotamia. The Prophet Muhammad himself is said to have traded in grain as a young man.

3.2 After the Conquests: The Transformation

ConquestAgricultural Impact
Syria (636 CE)Access to the grain-producing regions of the Levant
Iraq (637 CE)Control of the Mesopotamian breadbasket (the Sawad)
Egypt (641 CE)Control of the Nile Valley, Rome's primary grain source
Iran (642-651 CE)Access to diverse agricultural regions

The phrase "began for the first time to have rice and flour" is not literally true—Arabs had access to these goods before—but it captures a deeper truth: for the first time, these products were produced within lands ruled by Arabs, not imported from hostile empires.

3.3 The Symbolic Meaning

For the Tang scribe, the mention of rice and flour would have been significant. In Chinese bureaucratic thought, a state's ability to feed itself was a mark of civilization. The Arabs, previously known as pastoral nomads, had now acquired the agricultural foundation of a true empire. This single line signals that the Caliphate had transformed from a conquering horde into a settled, stable civilization.

🕉️ LINE 4: The Invasion of India

Text: 又將兵南侵婆羅門

Translation: "They also led troops south to invade the Brahmins [India]"

🔍 Commentary

The term 婆羅門 (Póluómén) literally means "Brahmins" but was used by Tang writers as a general term for India, reflecting the prominence of the priestly caste in Chinese perceptions of the subcontinent.

4.1 The Historical Context: Muʿāwiya's Eastern Expansion

Khalifa ibn Khayyat's History preserves detailed records of Umayyad raids into the Indian subcontinent during the first decade of Muʿāwiya's reign (661-670 CE). These campaigns, often overlooked in favor of the more famous western conquests, represent a sustained effort to extend Arab power into the Indus Valley.

4.2 The Significance of "Brahmins"

The choice of "Brahmins" to refer to India is telling:

AspectSignificance
Religious CasteBrahmins were the priestly class, the most visible representatives of Hindu civilization
Cultural MarkerTang China knew India primarily through Buddhism; "Brahmins" distinguished Hindu from Buddhist traditions
Geographical ScopeThe term encompassed both the Indus Valley (modern Pakistan) and the Gangetic plain

The raids described by Khalifa ibn Khayyat took place in the regions of Sind, Makran, and Qiqan—the frontier zones between the Iranian plateau and the Indian subcontinent. These were lands inhabited by populations that were predominantly Buddhist or Hindu, and which had been under Sassanian influence before the conquest.

4.3 The Muhallab Campaign (44 AH / 664-665 CE)

Khalifa's account of al-Muhallab's raid is particularly detailed:

"In this year, al-Muhallab b. Abi Sufra raided al-Hind. He marched to Qandabil, then he reached Banna and [another location], which are at the foot of the mountain of Kabul. A number [of people] confronted them, but God put them to rout. The Muslims filled their hands with booty and departed unharmed."

LocationIdentification
QandabilModern Gandava in Balochistan, Pakistan
BannaMAodern Bannu in Khyber Pakhtunkhwa
"Foot of the mountain of Kabul"The passes leading from the Iranian plateau into the Indus Valley

This was not a conquest but a raid—a demonstration of force, a collection of booty, and a strategic probing of Indian defenses. But it established a pattern that would continue for centuries: Muslim armies pushing eastward, seeking to extend the Caliphate's reach.

4.4 The Career of ʿAbdallāh b. Sawwār al-ʿAbdī

Khalifa's entries on Ibn Sawwār are particularly instructive:

YearEventOutcome
45 AHConquest of QiqanSuccess; booty including prized horses
47 AHSecond raid on QiqanDefeat and death; Turks retake the region

The Tang text's claim that the Arabs "invaded the Brahmins" is confirmed by these records—but so is the reality that these campaigns were not always successful. Ibn Sawwār's death in 667-668 CE, just six years after Muʿāwiya's accession, shows that the Indian frontier remained contested.

🏴‍☠️ LINE 5: The Annexation of Barbarian Kingdoms

Text: 吞並諸胡國

Translation: "annexing various barbarian kingdoms"

🔍 Commentary

This phrase captures the broader pattern of Umayyad expansion beyond the core territories of the former Sassanian and Roman empires.

The Tang scribe's use of "barbarian kingdoms" (諸胡國, zhū hú guó) reflects the Chinese view of the numerous small states and tribal confederations that dotted the region between Persia and India. These were precisely the targets of the raids recorded by Khalifa ibn Khayyat.

Year (AH)TargetCommanderOutcome

46Zabulistan, Rukhkhaj, Bustar-Rabīʿ b. ZiyādDefense against Turkish counter-attack
47QiqanʿAbdallāh b. SawwārDefeat and death

These campaigns represent a systematic effort to subdue the buffer states and principalities that had once paid allegiance to the Sassanian Empire. The "barbarian kingdoms" were being absorbed, one by one, into the Caliphate's expanding frontier.

⚔️ LINE 6: The Military Machine

Text: 勝兵四十餘萬

Translation: "and had over 400,000 elite soldiers"

🔍 Commentary

This figure, while likely an exaggeration, reflects the enormous military power that the Umayyad Caliphate could project by the 660s.

The figure of 400,000 is almost certainly a rounded estimate based on:

  • Reports of multiple armies operating simultaneously

  • Inclusion of garrison troops across the empire

  • Exaggeration by envoys seeking to impress the Tang court

6.2 What "勝兵" (Elite Soldiers) Implies

The term 勝兵 (shèng bīng) means "victorious troops" or "elite soldiers." It suggests:

ImplicationMeaning
ProfessionalizationNot just tribal levies, but standing forces
Combat experienceVeterans of decades of conquest
DisciplineOrganized military structure
Success rateUndefeated track record against two empires

By 661 CE, the Arab armies had never lost a major battle against a great power. Yarmūk, Qādisiyyah, Nihāwand—each was a decisive victory. The aura of invincibility was real, and the Tang court was being informed of it.

CONCLUSION: The Portrait of an Empire at Its Peak

The Old Book of Tang's account of the events around 661 CE captures the Umayyad Caliphate at a moment of transformation:

ElementHistorical RealityText's Accuracy
Date (Longshuo era)661 CE, Muʿāwiya's accession✅ Perfect
Defeat of PersiaComplete by 651 CE✅ Accurate
Defeat of RomeLoss of Syria, Egypt, Africa by 647 CE✅ Accurate
Agricultural transformationAccess to Syrian, Egyptian, Iraqi grain✅ Insightful
Invasion of IndiaRaids recorded in Khalifa (42-48 AH)✅ Confirmed
Annexation of border kingdomsSijistan, Zabulistan, Kabul, Makran✅ Confirmed
Army size400,000 (exaggerated but indicative)⚠️ Plausible impression

The Tang scribe, relying on reports from Umayyad envoys or from intermediaries who had spoken with them, constructed a remarkably accurate portrait of the new world power to the west. He understood that:

  • The old empires were defeated

  • A new political order had emerged (the Umayyad Caliphate)

  • This order was based on military power

  • It was expanding in multiple directions

  • It had acquired the agricultural base of a true civilization

  • It posed a potential threat—or opportunity—to Tang interests in Central Asia

The phrase "over 400,000 elite soldiers" may be an exaggeration, but it conveys an essential truth: by 661 CE, the Umayyad Caliphate was the most powerful military state between the Mediterranean and the Indus. The Tang court, with its own ambitions in Central Asia, could not afford to ignore this new player.

SECTION IV: The Marwanid Embassies — From ʿAbd al-Malik to Sulaymān (701-717 CE)

Text: 長安中,遣使獻良馬。景雲二年,又獻方物。開元初,遣使來朝,進馬及寶鈿帶等方物。其使謁見,唯平立不拜,憲司欲糾之,中書令張說奏曰:「大食殊俗,慕義遠來,不可置罪。」上特許之。」尋又遣使朝獻,自云在本國惟拜天神,雖見王亦無致拜之法,所司屢詰責之,其使遂請依漢法致拜。

At the beginning of the Kaiyuan period [713-741 CE], they sent envoys to court, presenting horses and precious inlaid belts and other local products. When the envoys had an audience, they merely stood upright and did not bow. The censorate wanted to impeach them, but the President of the Secretariat, Zhang Yue, memorialized: 'The Dàshí have different customs; they have come from afar admiring righteousness—they cannot be charged with a crime.' The Emperor specially permitted this. Soon afterwards, they again sent envoys to court with tribute, stating that in their country they only bow to the Heavenly God, and even when seeing their king, they have no practice of prostrating themselves. The relevant officials repeatedly questioned them about this, and the envoys then requested to perform the prostration according to Chinese custom."

📜 LINE 1: The First Marwanid Embassy — ʿAbd al-Malik (701-704 CE)

Text: 長安中,遣使獻良馬。

Translation: "During the Chang'an period [701-704 CE], they sent envoys presenting fine horses."

🔍 Commentary

The Chang'an period (長安中) corresponds to the latter part of the reign of Emperor Wu Zetian (r. 690-705 CE), the only woman to rule China in her own right. This embassy arrived during a period of intense diplomatic activity at the Tang court.

By 701 CE, ʿAbd al-Malik had firmly established Umayyad control after the chaos of the Second Fitna (680-692 CE). He was the architect of the mature Umayyad state:

Centralization690s CEReduced power of provincial governors

1.2 The Gift: Fine Horses

Horses were a traditional diplomatic gift across the Silk Road. The presentation of "fine horses" (良馬, liáng mǎ) suggests:

ImplicationMeaning
Recognition of Tang powerOffering tribute acknowledged Tang supremacy (in Chinese diplomatic framing)
Military signalingArabs had access to prized horse breeds (Arabian, Turkmen)
Economic exchangeHorses were a major trade commodity

The choice of horses as a gift is significant—it reflects the pastoral heritage of the Arabs and their reputation as horsemen, which the Tang would have appreciated as a fellow horse-using civilization.

📜 LINE 2: The Second Marwanid Embassy — Al-Walīd I (711 CE)

Text: 景雲二年,又獻方物。

Translation: "In the second year of the Jingyun era [711 CE], they again presented local products."

🔍 Commentary

The second year of Jingyun corresponds to 711 CE, during the reign of Emperor Ruizong of Tang (r. 710-712 CE). This embassy arrived at a moment of transition, as the Tang court was recovering from the turmoil of Empress Wei's failed usurpation.

2.1 The Caliph: Al-Walīd I ibn ʿAbd al-Malik (r. 705-715 CE)

AspectDetails
Reign705-715 CE
DynastyMarwanid Umayyad
CapitalDamascus
Major AchievementsExpansion to farthest extent; construction of Umayyad Mosque; patronage of arts

Al-Walīd I's reign marked the zenith of Umayyad power:

ConquestDateSignificance

Sind712 CEMuhammad b. al-Qasim conquers the Indus Valley
Spain711 CETāriq b. Ziyād crosses the Strait of Gibraltar
Anatolia710s CEAnnual raids into Roman territory

2.2 The Timing: 711 CE — A Watershed Year

In 711 CE, the Umayyad Caliphate was at the height of its expansion:

FrontEvent
WestTāriq b. Ziyād lands in Spain; beginning of conquest of Visigothic kingdom
EastQutayba b. Muslim conquers Khwarazm; presses toward China's Central Asian sphere
SouthMuhammad b. al-Qasim begins campaign in Sind
NorthAnnual raids into Anatolia continue

The embassy of 711 CE thus arrived at a moment when the Umayyads were simultaneously expanding in every direction—including toward the borders of Tang influence in Central Asia. This was not merely a diplomatic courtesy; it was a strategic communication between two expanding empires.

📜 LINE 3: The Kaiyuan Embassies — Sulaymān and His Successors (713-741 CE)

Text: 開元初,遣使來朝,進馬及寶鈿帶等方物。

Translation: "At the beginning of the Kaiyuan period [713-741 CE], they sent envoys to court, presenting horses and precious inlaid belts and other local products."

🔍 Commentary

The Kaiyuan era (開元, 713-741 CE) was the longest and most prosperous reign of Emperor Xuanzong (r. 712-756 CE), often considered the golden age of the Tang Dynasty. The embassy "at the beginning" of this period would have arrived around 713-715 CE.

3.1 The Caliph: Sulaymān ibn ʿAbd al-Malik (r. 715-717 CE)

AspectDetails
Reign715-717 CE
DynastyMarwanid Umayyad

The embassy likely arrived just as Sulaymān was coming to power. His brief reign is notable for:

Death717 CEDied while preparing to lead the siege personally

3.2 The Gifts: Horses and Precious Inlaid Belts

GiftSignificance
HorsesContinuing tradition of equestrian gifts; Arab horses still prized
寶鈿帶 (bǎo tián dài) — Precious inlaid beltsHigh-status diplomatic gifts; belts with inlaid gold, silver, jewels

Precious belts were particularly significant in both Arab and Chinese cultures:

CultureBelt Symbolism
ArabBelts with precious inlays were markers of rank and honor
ChineseOfficial belts (帶, dài) denoted bureaucratic rank; jade belts for highest officials

The presentation of such belts suggests:

  • High status of the envoys

  • Recognition of Tang China's prestige

  • Exchange of luxury goods along the Silk Road

3.3 The Diplomatic Context: Umayyad-Tang Rivalry in Central Asia

By 713-715 CE, the Umayyad and Tang empires were on a collision course in Central Asia:

YearEventSignificance
705Qutayba b. Muslim appointed governor of KhurasanBeginning of systematic Umayyad push east
706-709Conquest of BukharaMajor Sogdian city falls to Arabs
710-712Conquest of Samarqand, Khwarazm, FarghanaUmayyads reach the Jaxartes (Syr Darya)
712Kül Tegin inscriptions in MongoliaTürgesh and other Türkic powers caught between Tang and Umayyads
713Qutayba b. Muslim campaigns in FarghanaDirectly approaches Tang sphere of influence
715Death of al-Walīd I; Qutayba rebels and diesUmayyad advance temporarily halted

The embassies of this period were therefore not mere courtesies. They were communications between two superpowers whose spheres of influence were beginning to overlap in Central Asia. The gifts and diplomatic exchanges served as:

  • Reconnaissance (learning about the other power)

  • Signaling (showing strength and wealth)

  • Negotiation (establishing terms of engagement)

📜 LINE 4: The Protocol Crisis — Refusing to Bow

Text: 其使謁見,唯平立不拜,憲司欲糾之,中書令張說奏曰:「大食殊俗,慕義遠來,不可置罪。」上特許之。」

Translation: "When the envoys had an audience, they merely stood upright and did not bow. The censorate wanted to impeach them, but the President of the Secretariat, Zhang Yue, memorialized: 'The Dàshí have different customs; they have come from afar admiring righteousness—they cannot be charged with a crime.' The Emperor specially permitted this."

🔍 Commentary

This passage provides a rare glimpse into the actual mechanics of diplomatic protocol at the Tang court—and the cultural friction that could arise when civilizations with different customs met.

4.1 The Issue: Prostration (拜, bài)

In Chinese imperial protocol, foreign envoys were required to perform the koutou (叩頭, kòutóu)—a series of prostrations before the emperor. This act symbolized:

SymbolismMeaning
SubmissionRecognition of the emperor as "Son of Heaven"
TributeAcceptance of vassal status (in Chinese framing)
RespectProper acknowledgment of supreme authority

The Arab envoys refused. They stood upright (平立, píng lì) and did not bow.

4.2 Why They Refused: Islamic Practice

The text later explains their reasoning: "in their country they only bow to the Heavenly God, and even when seeing their king, they have no practice of prostrating themselves."

This reflects authentic Islamic practice:

Islamic PrincipleApplication
Tawḥīd (Unity of God)Worship directed only to Allah
Prostration (sujūd)Reserved for prayer to God alone
Caliphal protocolCaliphs were respected but not worshipped; no prostration

The envoys were not being arrogant or disrespectful. They were adhering to a fundamental principle of their faith: that prostration is an act of worship due only to God. To prostrate before a human ruler would be, in their understanding, a form of shirk (associating partners with God).

4.3 The Tang Response: Zhang Yue's Intervention

Zhang Yue (張說, 667-730 CE) was one of the most important figures of the early Kaiyuan era:

RoleSignificance
President of the SecretariatHead of one of the three highest departments of government
Scholar-officialRenowned poet, writer, and statesman
Advisor to XuanzongKey figure in the restoration of efficient government

His argument was masterful:

ArgumentTranslationPurpose
"大食殊俗""The Dàshí have different customs"Cultural relativism; acknowledges difference
"慕義遠來""they have come from afar admiring righteousness"Emphasizes their goodwill and long journey
"不可置罪""they cannot be charged with a crime"Pragmatic conclusion; avoids diplomatic incident

The Emperor "specially permitted" (特許, tè xǔ) this exception—a significant concession that shows:

  • Tang willingness to accommodate foreign customs

  • Recognition of the Arabs' importance as diplomatic partners

  • Zhang Yue's persuasive skill

4.4 Historical Significance

This incident is the earliest recorded example of Islamic religious practice coming into direct contact with Chinese imperial protocol. It reveals:

InsightImplication
Islamic monotheismThe envoys' refusal was theological, not political
Tang flexibilityThe court could accommodate difference when necessary
Zhang Yue's wisdomA skilled statesman prevented a diplomatic crisis
Mutual respectBoth sides eventually found a compromise

📜 LINE 5: The Resolution — Adapting to Chinese Custom

Text: 尋又遣使朝獻,自云在本國惟拜天神,雖見王亦無致拜之法,所司屢詰責之,其使遂請依漢法致拜。

Translation: "Soon afterwards, they again sent envoys to court with tribute, stating that in their country they only bow to the Heavenly God, and even when seeing their king, they have no practice of prostrating themselves. The relevant officials repeatedly questioned them about this, and the envoys then requested to perform the prostration according to Chinese custom."

🔍 Commentary

This passage records the resolution of the protocol crisis—and provides crucial insight into the theological basis of the envoys' refusal.

5.1 The Explanation: "We Only Bow to the Heavenly God"

The envoys explicitly state their religious principle:

PhraseTranslationArabic Equivalent
"惟拜天神" (wéi bài tiān shén)"only bow to the Heavenly God"لا نسجد إلا لله (lā nasjudu illā li-Llāh)

The term "天神" (tiān shén) — "Heavenly God" — is the same term used earlier to describe Arab religious practice. It reflects:

  • Tang understanding of Islamic monotheism

  • Identification of Allah with the Chinese concept of a supreme celestial deity

  • Recognition that Arab worship was directed to one God, not many

5.2 The Second Principle: "Even When Seeing Their King"

The envoys add another crucial detail: "even when seeing their king, they have no practice of prostrating themselves."

This reflects authentic Umayyad court protocol:

AspectPractice
Caliphal audienceSubjects stood, sat, or knelt; did not prostrate
TitlesCaliph addressed as "Commander of the Faithful" (Amīr al-Mu'minīn)
Respect shownThrough speech, gifts, and demeanor—not prostration

The envoys were explaining that their refusal was not directed specifically at the Tang emperor—it was a universal principle of their faith and culture.

5.3 The Pressure: "Repeatedly Questioned"

The phrase "所司屢詰責之" (suǒ sī lǚ jié zé zhī) — "the relevant officials repeatedly questioned them about this" — suggests:

ImplicationMeaning
Persistent pressureOfficials did not simply accept the first refusal
Cultural negotiationBoth sides engaged in discussion about the issue
Possible harassmentThe envoys may have been subjected to repeated demands

The Tang bureaucracy was not unified in its willingness to accommodate foreign customs. The censorate (憲司, xiàn sī) had wanted to impeach the envoys; now other officials were questioning them repeatedly.

5.4 The Resolution: "They Then Requested to Perform the Prostration"

Finally, the envoys agreed to perform the prostration according to Chinese custom.

This was likely a pragmatic decision:

FactorConsideration
Diplomatic necessityFailure to perform the ritual could end diplomatic relations
Economic interestsTrade and exchange depended on good relations
Political pressureRepeated questioning made continued refusal untenable
Theological accommodationThey may have reasoned that forced prostration under duress was not true worship

The phrase "依漢法致拜" (yī Hàn fǎ zhì bài) — "perform the prostration according to Chinese custom" — is carefully worded. It suggests:

  • They were following Chinese law, not their own

  • The act was diplomatic, not religious

  • They were accommodating the host culture's expectations

5.5 The Caliphs Behind the Embassies

Jeffrey Kotyk's dating places these embassies within specific caliphal reigns:

PeriodDateCaliphReign
Chang'an period701-704 CEʿAbd al-Malik685-705 CE
Jingyun 2711 CEAl-Walīd I705-715 CE
Kaiyuan period713-741 CESulaymān (715-717) and successors715-750 CE

The protocol crisis likely occurred during the reign of Sulaymān (715-717 CE) or one of his immediate successors—either ʿUmar II (717-720 CE) or Yazīd II (720-724 CE). The embassy that eventually agreed to prostrate would have been responding to pressure accumulated over multiple visits.

CONCLUSION: The Marwanid Embassies and Tang Diplomacy

The Old Book of Tang's record of Marwanid embassies provides a unique window into Umayyad-Tang relations during the Caliphate's golden age:

EmbassyDateCaliphGiftsSignificance
First701-704 CEʿAbd al-MalikFine horsesFirst contact after Umayyad consolidation
Second711 CEAl-Walīd ILocal productsEmbassy at peak of Umayyad expansion
Third713-715 CESulaymānHorses, precious beltsArrival during Central Asian campaigns
Protocol crisis715-717 CESulaymān/ʿUmar IITheological negotiation over prostration
Resolutionc. 717-720 CEʿUmar II/Yazīd IIEnvoys agree to prostrate

The passage reveals several key insights:

InsightImplication
Sustained diplomatic contactMultiple embassies over two decades
High-level giftsHorses and precious belts indicate importance
Religious sensitivityEnvoys explained Islamic practice to Chinese officials
Tang flexibilityZhang Yue's intervention prevented crisis
Cultural negotiationBoth sides eventually reached accommodation
Caliphal continuityEmbassies continued across multiple reigns

The mention of "only bowing to the Heavenly God" is particularly significant. It represents one of the earliest explanations of Islamic monotheism recorded in a non-Muslim source, preserved in the official history of Tang China.

🔍 Commentary

This single line encapsulates the most dramatic geopolitical shift of the early 8th century: the extension of Umayyad power into Transoxiana and its collision with the Tang sphere of influence.

1.1 The Kingdoms Identified

Chinese NameMiddle Chinese (EMC)IdentificationModern Location
康國 (Kāng guó)/kʰɑŋ kwək/SamarqandUzbekistan
石國 (Shí guó)/dʑiᴇk kwək/Chach / TashkentUzbekistan

康國 (Kāng) — Samarqand:

Samarqand was the jewel of Sogdia, one of the great cities of the Silk Road. Its name in Chinese, 康 (Kāng), derives from the Sogdian dynastic name kāng and reflects centuries of close contact between Sogdian merchants and the Tang court.

AspectDetails
Sogdian nameSamarkand (Sogdian: smʼrknδh)
Chinese name康國 (Kāng guó)
Strategic importanceCrossroads of Silk Road; center of trade, culture, and religion

石國 (Shí) — Chach / Tashkent:

Tashkent, known in Islamic sources as al-Shāsh and in Persian as Chach, was the northernmost of the great Sogdian cities.

AspectDetails
Sogdian nameChach
Arabic nameal-Shāsh
Chinese name石國 (Shí guó) — "Stone Kingdom"
Modern nameTashkent (Uzbek: "Stone City") — preserves the meaning

1.2 The Conquest of Transoxiana

The submission of Samarqand and Tashkent to Umayyad authority was the result of a sustained campaign under the governorship of Qutayba ibn Muslim (705-715 CE):

YearEventSignificance
705Qutayba ibn Muslim appointed governor of KhurasanBeginning of systematic Umayyad push east
706-709Conquest of BukharaMajor Sogdian city falls after multiple campaigns
710-712Conquest of SamarqandThe greatest prize of Transoxiana
712Conquest of KhwarazmNorthern campaign secures the Oxus delta
713Conquest of Shash (Tashkent)Umayyads reach the Jaxartes (Syr Darya)
713-714Campaigns in FarghanaPushing toward the borders of Chinese influence

The phrase "皆臣屬之" (jiē chén shǔ zhī) — "were all their vassals" — accurately reflects the situation by 714-715 CE. The great cities of Sogdia, which had once been independent or subject to Western Turkic overlordship, now acknowledged Umayyad authority.

The Tang court, receiving reports from Sogdian merchants and envoys, would have been acutely aware of this transformation. The cities that had once sent tribute to Chang'an now sent it to Damascus.

📜 LINE 2: The Scale of Empire

Text: 其境東西萬里

Translation: "Their territory stretched ten thousand li from east to west"

🔍 Commentary

This figure, while approximate, captures the immense scale of the Umayyad Caliphate at its height.

2.1 The Meaning of "Ten Thousand Li" (萬里)

In Chinese geographical writing, 萬里 (wàn lǐ) — "ten thousand li" — was often used as a conventional expression meaning "immense" or "boundless." However, it also had a literal basis:

UnitLength
1 li (里)Approximately 0.5 km (varies by period)
10,000 liApproximately 5,000 km

2.2 The Actual Extent of the Umayyad Caliphate (c. 715 CE)

BoundaryLocationApproximate Longitude
Western limitAtlantic coast (Spain/Morocco)10° W
Eastern limitFerghana Valley / Jaxartes River75° E
Total span85° of longitude

At the equator, 85° of longitude equals approximately 9,500 km. At the latitudes of the Caliphate (30-40° N), the actual distance is somewhat less:

SegmentDistance (km)
Atlantic to Damascus~5,000 km
Damascus to Ferghana~3,500 km
Total~8,500 km

8,500 km = approximately 17,000 li (using 0.5 km/li)

The figure "10,000 li" is therefore a reasonable rounded estimate—not an exaggeration, but a conservative approximation of the Caliphate's true extent.

2.3 Comparative Scale

To appreciate the Umayyad Caliphate's size, consider these comparisons:

EmpireMaximum Extent (km east-west)Notes
Umayyad Caliphate (715 CE)~8,500 kmFrom Spain to Central Asia
Achaemenid Persian Empire~5,000 kmFrom Egypt to Indus
Roman Empire~4,500 kmFrom Britain to Mesopotamia
Tang Empire~4,000 kmFrom Korea to Central Asia

By 715 CE, the Umayyad Caliphate was the largest empire the world had yet seen, spanning the entire breadth of the civilized world from the Atlantic to the Indus.

📜 LINE 3: The Eastern Frontier

Text: 東與突騎施相接焉。

Translation: "and in the east they bordered the Türgesh."

🔍 Commentary

This final line identifies the critical frontier where Umayyad expansion met its match—and where Tang interests were most directly engaged.

3.1 Who Were the Türgesh?

突騎施 (Túqíshī) refers to the Türgesh (or Türgish), a powerful Türkic confederation that dominated the western steppe in the early 8th century.

AspectDetails
EthnicityTürkic
RegionSemirechye (Zhetysu) — "Land of Seven Rivers"
CapitalSuyab (near modern Tokmok, Kyrgyzstan)
Period of dominancec. 699-766 CE
ReligionTengrism (traditional Türkic beliefs); later接觸 Buddhism and Nestorian Christianity

The Türgesh emerged as the dominant power in the western steppe after the collapse of the Western Turkic Khaganate. By 715 CE, they controlled the region between the Jaxartes (Syr Darya) and the Altai Mountains, directly bordering:

NeighborRelationship
Umayyad CaliphateHostile; contested control of Transoxiana
Tang EmpireComplex; sometimes allies, sometimes rivals
TibetOccasionally allied against Tang
KhazarsDistant relations across the steppe

3.2 The Türgesh-Umayyad Conflict

The Türgesh were the primary obstacle to Umayyad expansion beyond the Jaxartes:

YearEventSignificance
712Türgesh intervene in SogdiaFirst major clash with Umayyads
717Türgesh attack Umayyad garrisonsOpen warfare begins
720sTürgesh raids into TransoxianaConstant pressure on Umayyad positions
724"Day of Thirst" — Umayyad army destroyedTürgesh annihilate Umayyad force in Farghana
730sContinued warfareUmayyads struggle to hold Transoxiana
737Battle of KharīstānUmayyad victory breaks Türgesh power

The phrase "東與突騎施相接" (dōng yǔ Túqíshī xiāng jiē) — "in the east they bordered the Türgesh" — accurately describes the situation in the early 8th century. The Umayyad frontier ended at the Jaxartes; beyond lay the steppe, dominated by the Türgesh.

3.3 The Tang Connection

For the Tang court, the Türgesh were a familiar presence:

AspectDetails
RelationsAlternating between alliance and hostility
Capital SuyabSite of Tang protectorate (until 719)
DiplomacyTang, Türgesh, and Umayyads engaged in complex three-way relations
Strategic importanceTürgesh buffer zone prevented direct Tang-Umayyad border

By noting that the Umayyads bordered the Türgesh, the Tang scribe was implicitly noting that the Caliphate had not yet reached Tang territory. The Türgesh served as a buffer—a role they would continue to play until their destruction in the 740s.

CONCLUSION: The Umayyad Empire Through Tang Eyes

This brief passage provides a remarkably accurate snapshot of the Umayyad Caliphate at its height:

ElementTextHistorical RealityAccuracy
Sogdian submission康國、石國之類,皆臣屬之Samarqand and Tashkent conquered by Qutayba (705-715)✅ Perfect
Western extent(implied)Atlantic coast of Spain and Morocco✅ (not stated but correct)
Eastern extent東西萬里~8,500 km from Atlantic to Jaxartes✅ Reasonable estimate
Eastern neighbor東與突騎施相接Türgesh confederation dominant beyond Jaxartes✅ Perfect

The Tang scribe understood that:

  • The Umayyads had absorbed the great Sogdian cities

  • Their empire was vast—larger than any the Chinese had previously encountered

  • They had not yet reached Tang territory, but bordered the Türgesh

  • The Türgesh were the critical buffer between the two superpowers

This single sentence, read in context, reveals the strategic situation that would define Central Asian geopolitics for the next three decades: two expanding empires, separated by a Türkic confederation, each watching the other with wary attention.

SECTION VI: The Abbasid Account — From White Robes to Black Robes and a Century of Diplomacy

Text: 一云隋開皇中,大食族中有孤列種代為酋長,孤列種中又有兩姓:一號盆泥奚深,一號盆泥末換。其奚深後有摩訶末者,勇健多智,眾立之為主,東西征伐,開地三千里,兼克夏臘,一名釤城〈(釤音所鑒反)〉。摩訶末後十四代,至末換。末換殺其兄伊疾而自立,復殘忍,其下怨之。有呼羅珊木粗人並波悉林舉義兵,應者悉令著黑衣,旬月間眾盈數萬。鼓行而西,生擒末換,殺之。遂求得奚深種阿蒲羅拔,立之。末換已前謂之「白衣大食」,自阿蒲羅拔後改為「黑衣大食」。阿蒲羅拔卒,立其弟阿蒲恭拂。至德初遣使朝貢,代宗時為元帥,亦用其國兵以收兩都。寶應、大曆中頻遣使來。恭拂卒,子迷地立。迷地卒,子牟棲立,牟棲卒,弟訶論立。貞元中,與吐蕃為勍敵。蕃軍太半西禦大食,故鮮為邊患,其力不足也。十四年,詔以黑衣大食使含嵯、焉雞、沙北三人並為中郎將,各放還蕃。

Translation: "Another account says: In the Sui Kaihuang era [581-600 CE], among the Da Shi (Arab) people, the Gulie tribe successively served as chieftains. Within the Gulie tribe, there were two clans: one was called Penni Xishen, and the other was called Penni Mohuan. From the Xishen [Banū Hāshim] thereafter, there was Mòhēmò [Muhammad]. He was brave, robust, and full of wisdom; the people established him as their ruler. He launched expeditions east and west, opening up [conquering] three thousand li of territory, and additionally vanquished Xialà [al-Ḥīra] and also a place called Shancheng [al-Shām/Damascus). 

After Mòhēmò, [after] fourteen generations, they reached Mòhuàn [Marwān II]. Mòhuàn killed his elder brother Yījí [Yazīd III] and set himself up [as ruler]. Furthermore, he was cruel and brutal, and those under him resented him. There was a man from Khorasan, a Mùcū [Mawlā/client] named Bìngbōxīlín [Abū Muslim], who raised a righteous army. He ordered all who responded to wear black clothes. Within a month, his followers numbered in the tens of thousands. They advanced westward with drumming [of war], captured Mòhuàn alive, and killed him. Thereupon, they sought out and found a descendant of the Xīshēn (Hāshim) line, Āpú Luóbá [Abū al-ʿAbbās], and established him [as ruler]. The period before Mòhuàn was called the 'White Robed Da Shi,' and from Āpú Luóbá onward, it was changed to the 'Black Robed Da Shi.' 

Āpú Luóbá died, and his younger brother, Āpú Gōngfú [Abū Jaʿfar al-Manṣūr], was established. In the early Zhide era [756 CE], he sent envoys who presented tribute at court. During the reign of Emperor Daizong, while he was still a Marshal, he also used troops from that country to recapture the Two Capitals. During the Baoying [762-763 CE] and Dali [766-779 CE] eras, they frequently sent envoys. Āpú Gōngfú died, and his son Mídì [al-Mahdī] was established. Mídì died, and his son Móuqī [al-Hādī] was established. Móuqī died, and his younger brother Hēlùn [Hārūn al-Rashīd] was established. 

During the Zhenyuan era [785-805 CE], they became fierce enemies of the Tibetans. The Tibetan army, for the most part, was deployed westward to defend against the Da Shi, and thus they rarely posed a border threat [to us], as their strength was insufficient. 

In the 14th year [of Zhenyuan, 798 CE], an edict appointed the three envoys of the Black-Robed Da Shi—Háncuó [Ḥammād], Yānjī [Yaḥyā], and Shāběi [Shihāb]—as Commandants of the Palace Guard and sent each back to their homeland."

📜 LINE 1: The Genealogical Foundation

Text: 一云隋開皇中,大食族中有孤列種代為酋長,孤列種中又有兩姓:一號盆泥奚深,一號盆泥末換。

Translation: "Another account says: In the Sui Kaihuang era [581-600 CE], among the Da Shi (Arab) people, the Gulie tribe successively served as chieftains. Within the Gulie tribe, there were two clans: one was called Penni Xishen, and the other was called Penni Mohuan."

🔍 Commentary

This opening line establishes the genealogical framework of the Abbasid narrative with remarkable precision.

盆泥末換 (Pénní Mòhuàn)/buan neh mɑt ɣuanh/Banū Marwān (بَنُو مَرْوَان)The Umayyad ruling line

The text immediately establishes a sophisticated understanding of Arabian social structure, correctly identifying:

  • The Quraysh as the ruling tribe

  • The Banū Hāshim as the prophetic line

  • The Banū Marwān as the Umayyad dynasty

This genealogical framing serves the Abbasid legitimizing narrative: the Umayyads are presented as one branch of the Quraysh, distinct from—and in competition with—the Hashemite line from which the Abbasids claimed descent.

📜 LINE 2: The Rise of the Prophet

Text: 其奚深後有摩訶末者,勇健多智,眾立之為主,東西征伐,開地三千里,兼克夏臘,一名釤城。

Translation: "From the Xishen [Banū Hāshim] thereafter, there was Mòhēmò [Muhammad]. He was brave, robust, and full of wisdom; the people established him as their ruler. He launched expeditions east and west, opening up [conquering] three thousand li of territory, and additionally vanquished Xialà [al-Ḥīra] and also a place called Shancheng [al-Shām/Damascus]."

釤城 (Shànchéng)/ʂam' dʑiaŋ/al-Shām (ٱلشَّام) / DamascusThe Levantine capital

The description of Muhammad as "brave, robust, and full of wisdom" (勇健多智, yǒng jiàn duō zhì) paints a portrait of an ideal tribal leader and strategist—consistent with Islamic tradition's view of Muhammad as a political and military leader.

The phrase "the people established him as their ruler" (眾立之為主, zhòng lì zhī wéi zhǔ) reflects the historical bayʿah (pledge of allegiance) and frames his authority as stemming from popular consent.

The telescoping of conquests—attributing to Muhammad himself the victories at al-Ḥīra (633 CE) and Damascus (635 CE)—is a narrative compression common in dynastic histories, attributing the momentum of early conquests to the founding figure.

📜 LINE 3: The Umayyad Usurpation

Text: 摩訶末後十四代,至末換。末換殺其兄伊疾而自立,復殘忍,其下怨之。

Translation: "After Mòhēmò, [after] fourteen generations, they reached Mòhuàn [Marwān II]. Mòhuàn killed his elder brother Yījí [Yazīd III] and set himself up [as ruler]. Furthermore, he was cruel and brutal, and those under him resented him."

伊疾 (Yījí)/ʔiəi dzit/Yazīd III (يَزِيد)Umayyad caliph (744 CE)

The "fourteen generations" refers to the fourteen Umayyad caliphs from Muʿāwiya I to Marwān II—a political count, not a biological one, reflecting the Abbasid view that the entire Umayyad dynasty was an illegitimate interruption.

The claim that Marwān II "killed his elder brother" is a narrative compression of the complex civil wars of 744-747 CE. Yazīd III died of natural causes after a six-month reign; Marwān II defeated and killed Ibrāhīm, Yazīd's brother and successor. The text telescopes these events into a simple fratricide—a powerful moral indictment in Confucian historiography.

The description of Marwān II as "cruel and brutal" (殘忍, cánrěn) is confirmed by Arabic sources, which record acts such as the blinding of Yazīd al-Qasrī. His subjects' resentment is reflected in his derogatory nickname "Marwān the Donkey" (مروان الحمار).

📜 LINE 4: The Abbasid Revolution

Text: 有呼羅珊木粗人並波悉林舉義兵,應者悉令著黑衣,旬月間眾盈數萬。鼓行而西,生擒末換,殺之。

Translation: "There was a man from Khorasan, a Mùcū [Mawlā/client] named Bìngbōxīlín [Abū Muslim], who raised a righteous army. He ordered all who responded to wear black clothes.

並波悉林 (Bìngbōxīlín)/biæŋ puɑ siɪt lɪm/Abū Muslim (أَبُو مُسْلِم)Abbasid revolutionary leader

The identification of Abū Muslim as a "Khorasani client" (木粗人) is historically precise. As a mawlā (non-Arab client) of the Banū Hāshim, he represented the marginalized non-Arab converts who powered the Abbasid revolution.

The black clothing (黑衣, hēi yī) was the signature of the Abbasid movement—a deliberate contrast to Umayyad white. Black symbolized:

  • Mourning for the martyrs of the Prophet's family

  • Vengeance against the unjust Umayyads

  • The banner of the Prophet (according to Abbasid propaganda)

The rapid growth ("within a month, his followers numbered in the tens of thousands") reflects the massive popular support for the Abbasid cause in Khurasan, where Umayyad rule was deeply resented.

The phrase "advanced westward with drumming" (鼓行而西, gǔ xíng ér xī) describes the Abbasid army's march from Khurasan to Iraq, culminating in the Battle of the Zab (750 CE) and the capture and execution of Marwān II in Egypt.

📜 LINE 5: The Hashemite Restoration

Text: 遂求得奚深種阿蒲羅拔,立之。末換已前謂之「白衣大食」,自阿蒲羅拔後改為「黑衣大食」。

The phrase "sought out and found" (求得, qiú dé) frames the Abbasid accession as a restoration, not a usurpation—they searched for the rightful Hashemite heir and installed him.

The color distinction between Umayyad white and Abbasid black is historically accurate and becomes the standard Chinese terminology for the two caliphates.

📜 LINE 6: The Early Abbasid Succession

Text: 阿蒲羅拔卒,立其弟阿蒲恭拂。至德初遣使朝貢,代宗時為元帥,亦用其國兵以收兩都。

The succession from al-Saffāḥ to al-Manṣūr is correctly recorded. Al-Manṣūr, the true architect of the Abbasid state, founded Baghdad in 762 CE.

The reference to Abbasid troops helping recapture the Two Capitals refers to the An Lushan Rebellion (755-763 CE). The Tang court, desperate for military aid, requested help from the Abbasids, who sent troops to assist in retaking Chang'an and Luoyang—a remarkable instance of military cooperation between the two greatest empires of the age.

🔍 Commentary

This passage describes one of the most significant strategic developments of the late 8th century: the Abbasid-Tibetan conflict, which greatly benefited the Tang.

PowerRelationship
Abbasid CaliphateExpanding into Central Asia, contesting Tibetan influence
Tibetan EmpireDominant in Central Asia, threatening Tang borders
Tang EmpireBeneficiary of Abbasid-Tibetan hostility

The phrase "fierce enemies" (勍敵, qíng dí) accurately describes the Abbasid-Tibetan rivalry, which played out in the mountains of the Pamirs and the valleys of Transoxiana. The result, from the Tang perspective, was a welcome relief: Tibetan forces were tied down in the west, unable to mount serious attacks on Tang territory

📜 LINE 9: The 798 CE Embassy

This final entry records a specific diplomatic event: the honoring of three Abbasid envoys in 798 CE, during the reign of Hārūn al-Rashīd (訶論). The bestowal of the title "Commandant of the Palace Guard" (中郎將, zhōng láng jiàng) was a standard Tang diplomatic practice, incorporating foreign envoys symbolically into the imperial structure.

The accuracy of the name transcriptions—Yaḥyā, Shihāb, Ḥammād—demonstrates the quality of Tang diplomatic record-keeping and the sustained nature of Sino-Abbasid contact.

CONCLUSION: The Abbasid Narrative Complete

This final section of the Old Book of Tang's account of the Arabs provides:

The Old Book of Tang thus concludes its account of the Arabs not with myth or legend, but with precise, verifiable diplomatic history—a testament to the quality of Tang record-keeping and the importance of Sino-Abbasid relations in the 8th century.

CONCLUSION — The Old Book of Tang and Its Amazing Value to Early Islamic History

The Old Book of Tang's account of the Arabs, spanning barely a few hundred characters across a single chapter, is one of the most remarkable documents for the study of early Islamic history. Its value lies not in its length, but in its heterogeneity—the fact that it preserves, side by side, two radically different narratives that no other source has transmitted.

NarrativeSourcePerspectiveValue
The Sassanian "Lion's Prophecy"Persian refugees (Pērōz III)Zoroastrian theological polemicOnly surviving account of Sassanian propaganda against Islam
The Abbasid Official HistoryAbbasid envoys and diplomatsIslamic dynastic legitimizationEarliest external confirmation of Islamic historical tradition

The Tang compilers, in their magnificent bureaucratic neutrality, did not attempt to reconcile these accounts. They did not judge one true and the other false. They simply recorded both, preserving for eternity the voices of both victor and vanquished.

Beyond its specific contents, the Old Book of Tang offers historians a methodological lesson:

PrincipleImplication
Neutral recordingThe compilers did not edit out material that seemed contradictory or bizarre
Multiple sources preservedThe "Persian Version" and "Arabian Version" sit side by side
Verbatim transmissionDocuments, titles, and names are transcribed phonetically
Chronological precisionDates are recorded with care, even when requiring calendar conversion
Diplomatic detailAmbassadors' names, gifts, and protocols are noted

The Old Book is not an interpretive history. It is a repository—a place where the Tang state deposited the information it received, without judgment, for future generations to consult.

The Old Book of Tang contains two Arab histories: one a fossil of Sassanian trauma, the other a flower of Abbasid diplomacy.

The fossil is the "Lion's Prophecy"—a Zoroastrian horror story in which a demonic lion (agent of Xēšm) corrupts a lowly camel-herder with a black stone (Ahrimanic artifact) found in three caves (inversion of Good Thoughts, Good Words, Good Deeds), leading to the destruction of Ērānshahr. This is the voice of a fallen empire, crying out across the centuries, preserved only because a Tang scribe wrote it down.

The flower is the Abbasid official history—a precise, accurate chronicle of dynastic succession, military expansion, and diplomatic contact. This is the voice of a new empire, confident in its power and eager to present itself to the other great civilization of the age.

Together, they form a stereoscopic view of one of history's greatest transformations. We see the rise of Islam through the eyes of those who benefited from it and those who were destroyed by it. We see both sides of the story, preserved in the same chapter, by the same scribes, in the same neutral tone.

The Old Book of Tang does not judge. It does not interpret. It simply remembers.

And because it remembers, we know that in 651 CE, an envoy from Caliph ʿUthmān stood before the Tang court and spoke of a Prophet, a community, and a state that was thirty-one years old. We know that in 661 CE, the Umayyads consolidated power and began expanding into India. We know that in 750 CE, black banners rose in Khorasan and overthrew the white-robed tyrants. We know that in 756 CE, Abbasid troops helped the Tang emperor regain his throne. And we know that in 798 CE, three men named Ḥammād, Yaḥyā, and Shihāb were honored in Chang'an before returning to the court of Hārūn al-Rashīd.

These are not legends. These are facts—preserved in ink, on paper, in a language half a world away from the events they describe, by scribes who had no religious or political stake in the story they were recording.

That is the miracle of the Old Book of Tang. That is its amazing value to early Islamic history.
