Dúduàn 獨斷

Solitary Decisions

by 蔡邕 (Cài Yōng, 132–192, zì Bó Jiē 伯喈; Yìláng 議郎 and Zuǒ Zhōnglángjiāng 左中郎將, principal Hàn polymath, calligrapher, and ritual specialist)

About the work

A two-juan systematic compendium on imperial institutions of the Eastern Hàn — by the conventional ascription, the work of the great late-Eastern-Hàn scholar Cài Yōng 蔡邕. Dúduàn is one of the most important pre-Suí sources for the structure of Hàn court ritual, imperial titulature, the formats of edicts and memorials, the imperial regalia, the system of fiefs, the Tàimiào 太廟 ancestral cult, the imperial pedigree from the Gāozǔ 高祖, the imperial regalia and chariots, the imperial seals, the dating system, and miscellaneous administrative protocol. It is the principal narrative source for the typology of imperial communications — the four kinds of imperial commands (cèshū 策書, zhìshū 制書, zhàoshū 詔書, jièchì 戒敕) and the four kinds of memorials to the throne (zhāng 章, zòu 奏, biǎo 表, yì 議) — and accordingly is among the central sources for the modern reconstruction of Hàn administrative documentary practice (Enno Giele’s 2006 monograph treats it as such). The text closes with an imperial pedigree extending from Gāozǔ to Língdì 靈帝 Jiànníng 5 [172], with a small-character extension covering events through Xiàndì 獻帝 — proof that the received recension has accreted post-Cài material. Catalogued under Záxué zhī shǔ 雜學之屬 of the Zájiā 雜家 division.

The Kanripo recension is the SBCK printing of the Míng Hóngzhì guǐhài 弘治癸亥 (1503) edition with the preface of Liú Sūn 劉遜.

We respectfully submit that Dúduàn in two juan was composed by Cài Yōng of the Hàn. Wáng Yìnglín’s 王應麟 Yùhǎi 玉海 says the book has occasional disorder; in the Jiāyòu 嘉祐 era [1056–1063] Yú Zézhōng 余澤中 re-ordered it and added his own explanations, hence a separate version was titled Xīndìng Dúduàn 新定獨斷. Yú’s revised text is no longer extant. Now in the present text, the section narrating the imperial line of successive generations ends with the words “from Gāozǔ yǐwèi down to the present rénzǐ year, three hundred and ten years”; rénzǐ is Língdì Jiànníng 5 [172]. But in the small-character note at the end of the Língdì genealogy line, there are events extending twenty-two years further; and there is also Xiàndì’s posthumous title — these must not be Cài’s original text, but later interpolations by another hand. The book follows the Lǐjì in matters of ritual rather than the Zhōuguān. As for the five-rank enfeoffment, it differs entirely from the Dà sītú 大司徒 [chapter of the Zhōulǐ]; but the explanation of each item agrees in many places with the Lǐ commentary of Zhèng Xuán 鄭玄 — the gloss on the Dàzhù 大祝 entry agrees with Zhèng Kāngchéng’s Dàzhù note word-for-word, so they must derive from a common source. Furthermore the Yúfú zhì 輿服志 of the Xù Hàn shū 續漢書 says that the cap of Fán Kuài 樊噲 is “nine cùn wide and seven cùn high, with four-cùn projections in front and behind”; this book gives “seven cùn wide, four-cùn projection in front” — its wording slightly differs. Liú Zhāo’s 劉昭 Yúfú zhì 輿服志 commentary cites Dúduàn: “the three gōng and the zhūhóu nine pendants, the qīng seven pendants”; the present text has “the three gōng nine, the zhūhóu and qīng seven.” The Jiànhuáguān 建華冠 note cites Dúduàn: “its shape is like a woman’s lǚlù 縷鹿 [hair-net]”; the present text has none of this. The Chūxué jì 初學記 cites Dúduàn: “those of the imperial vehicles which are paired with axle-pins have axle-pins fitted on the outside, then again set with axle-pins” — entirely different from the present. These may be transcriptional errors in the citing sources, or transmission losses in the present text — neither can now be known. Yet on the whole the book is structurally and conceptually coherent, and even with small inconsistencies its broad import is undamaged. It remains a treasure-trove of evidential investigation.

Abstract

Cài Yōng 蔡邕 (132–192, zì Bó Jiē 伯喈) was the foremost late-Eastern-Hàn polymath: classicist, calligrapher, fù-poet, musician, astronomer, and ritual specialist. As Yìláng 議郎 he led the cutting of the Xīpíng shíjīng 熹平石經 (175–183), the first state-sponsored stone redaction of the Five Classics; he was rehabilitated under Dǒng Zhuō 董卓, made Zuǒ Zhōnglángjiāng 左中郎將 (whence Cài Zhōngláng 蔡中郎), and condemned to die in prison by Wáng Yǔn 王允 in 192 for sighing at the news of Dǒng Zhuō’s assassination. Standard biography in Hòu Hàn shū 60B.

The conventional ascription of Dúduàn to Cài Yōng has been received from at least the Suí onward and is supported by the genealogical anchor in the text itself, which dates its terminus to Língdì Jiànníng 5 (172) — well within Cài’s productive lifetime. The dating bracket adopted here (notBefore 172, notAfter 192) reflects this internal anchor (172) and Cài’s death (192). The small-character extensions noted by the Sìkù editors (covering Xiàndì’s reign and his posthumous title) are clearly accreted post-Cài material; they cannot be later than the conventional SuíTáng terminus for the received text, but the substantive body is securely Eastern Hàn and almost certainly Cài’s. Modern scholarship — most importantly Enno Giele’s 2006 study — accepts the core of the text as Cài Yōng’s, while emphasising the strata of post-Hàn editorial intervention (some of it perhaps as early as the Jiāyòu 嘉祐 reorganisation of Yú Zézhōng).

The book is the principal narrative source for late-Hàn imperial documentary practice. Its typology of the four kinds of imperial commands and four kinds of memorials to the throne is the locus classicus for the formal categories that structured Han chancery output, and is therefore the foundation of the modern study of Hàn administrative communication, including the rich excavated jiǎndú 簡牘 corpus from Han military and provincial sites. It is also a major source for late-Hàn ritual reconstructions — its discussions of imperial regalia, the Tàimiào ancestral cult, the fēngshàn sacrifices, and fúshì 服飾 are foundational. Wilkinson (§59.6.6) places it under “Official Communications” as one of the two essential pre-modern sources, alongside Loewe (2004).

The work survives in 2 juan; it has been transmitted continuously since the Eastern Hàn through both the Záshuō and Zájiā catalogues. The Suí shū · Jīngjí zhì and Táng shū · Yìwén zhì both list it. The standard modern critical edition is the Sìkù-based recension (V850.2), supplemented by the Hóngzhì (1503) Liú Sūn edition reprinted in SBCK. The Hong Kong CHANT (ICS 36) provides a concordance.

Other points of interest

The text’s interest is two-fold. First, as a primary source: Cài Yōng was a serving Han official (Yìláng, Zuǒ Zhōnglángjiāng) and a participant-witness to the highest-level court ritual and chancery practice of the late second century, and Dúduàn preserves his categories. Second, as a target of textual criticism: the Sìkù tiyao is itself a model of QiánJiā era kǎozhèng practice, working through the discrepancies between the present recension and citations in Yùhǎi, Xù Hàn shū · Yúfú zhì, Liú Zhāo zhù, and Chūxué jì to map the layers of textual loss and editorial intervention. The text’s discussions of Hàn imperial titulature and the typology of edict-formats remain authoritative.
