Tàixuán jīng 太玄經
The Classic of Supreme Mystery (Yáng Xióng’s Yìjīng-paralleling cosmological treatise) by 揚雄 (Yáng Xióng, 53 BCE – 18 CE, 漢, zhuàn 撰); annotated by 范望 (Fàn Wàng, 晉, zhù 注)
About the work
Yáng Xióng’s monumental philosophical-cosmological treatise modeled on the Yìjīng but using a 9-fold cosmological structure (vs. the Yìjīng’s 8-fold), composed during the Wáng Mǎng usurpation period (roughly 2–4 CE). The work consists of:
- 3 fāng 方 (cardinal directions / cosmic-foundations)
- 9 zhōu 州 (provinces / regional-zones)
- 27 bù 部 (sections / divisional-units)
- 81 jiā 家 (lineages / cosmological-units — equivalent to the Yìjīng’s 64 hexagrams)
- 243 biǎo 表 (tables / position-statements — three for each jiā)
- 729 zàn 讚 (statements / line-statements — nine for each jiā; equivalent to the Yìjīng’s 384 line-statements but in a 9-fold rather than 6-fold scheme)
The 81 jiā are constructed from a 4-line tetragram (tóu 頭, “head”) with each of the 4 lines independently taking one of three values (---, —, -) — yielding 3⁴ = 81 distinct configurations, vs. the Yìjīng’s 6-line hexagrams with each line taking one of 2 values yielding 2⁶ = 64. The 9-fold structure is calendrically-aligned: the 729 zàn correspond to the days of a 729-day cycle that roughly matches the Tàichū 太初 calendar’s 81-day periods (since 729 = 81 × 9). The work’s calendrical-cosmological apparatus is one of its principal substantive contributions; the Tàixuán’s organization claims to map the actual structure of cosmic time.
Yáng Xióng’s authorial purpose was to complete (or perhaps correct) the Yìjīng by supplying a more thoroughgoing cosmological apparatus. His KR3g0002 commentator and admirer Yè Zǐqí 葉子奇 (Míng) would later write that “the Yì says: the great extension’s number is 50, [we] use 49; the Mystery says: the Heaven-Earth’s strategies are 19, [we] use 18” — a self-conscious parallel-construction. The relation between the Yì and the Tàixuán would continue to be debated through the Hàn-and-later commentarial tradition, with the Tàixuán generally taking a subordinate-but-respected position as a quasi-classic.
The work’s commentarial tradition began under the Eastern Hàn / early Wèi with Sòng Zhōng 宋衷 and the Three-Kingdoms Wú scholar Lù Jì 陸績, whose commentaries are partially lost but were synthesized by Fàn Wàng of the Western Jìn into the standard transmitted recension. Subsequent commentators include Wáng Yá 王涯 (Shuōxuán), Sīmǎ Guāng 司馬光 (Tàixuán jízhù), Yè Zǐqí 葉子奇 (KR3g0002 Tàixuán běnzhǐ), and many others.
The Sìkù editors’ decision to place the Tàixuán jīng in the shùshù (numerological / divinatory) class rather than the Rújiā (Confucian) class is interpretively significant: it positions the work as a numerological-cosmological text rather than a philosophical-canonical one. The chinaknowledge.de secondary source notes: “Yang Xiong’s book Taixuanjing was de-classified [in the Sìkù] and put into the sub-category of books on divination ( shùshù )“. This editorial decision reflects the high-Qīng kǎojù tendency to classify works by their substantive subject-matter rather than their authorial pedigree.
The Sìkù-recension presents the text in 10 juàn (per the Hàn-and-Western-Jìn-tradition arrangement). The Tang Yìwén zhì records 6 juàn; the Sòng Wénxiàn tōngkǎo records 10; the apparent discrepancy reflects different recension-arrangements with the same total content.
The 提要 records the editorial debate about the xuáncè 玄測 section’s positioning: Fàn Wàng’s recension positioned the xuáncè differently than earlier (Sòng Zhōng / Lù Jì) recensions, integrating the textual layers more closely. The Sìkù editors followed Fàn Wàng’s arrangement.

Abstract
Composition window: c. 2 – 4 CE. Yáng Xióng composed the Tàixuán jīng during the Wáng Mǎng era; his service at the Wáng Mǎng court damaged his posthumous reputation but did not erase the work’s intellectual stature.
The work’s significance:
(a) The systematic alternative-cosmology: the Tàixuán’s 9-fold cosmological structure represents the most ambitious systematic alternative to the Yìjīng’s 8-fold structure ever produced in the Chinese tradition. The two systems coexist throughout late-imperial Chinese cosmology, with the Yìjīng taking institutional priority but the Tàixuán providing the principal alternative reference for unconventional cosmological speculation.
(b) The calendrical-cosmological synthesis: the Tàixuán’s 729-fold periodicity (corresponding to the Tàichū calendar’s 81-day periods × 9) makes the work fundamentally calendrical in character — anticipating the long late-imperial Chinese tradition of cosmographic-calendrical synthesis.
(c) The literary-philosophical legacy: through the Tàixuán, Yáng Xióng established himself as the principal Hàn-period philosophical-and-literary innovator after Sīmǎ Xiāngrú. The 2nd-century xuánxué (Mystery-Learning) movement, the Six-Dynasties-and-Tang philosophical syntheses, and the Sòng Confucian revival all engage with the Tàixuán as a foundational reference.
(d) The commentarial tradition: the long sequence of commentators on the Tàixuán — Sòng Zhōng, Lù Jì, Fàn Wàng, Wáng Yá, Sīmǎ Guāng, Yè Zǐqí, and many others — constitutes one of the principal Chinese commentarial traditions, parallel to (though smaller than) the Yìjīng commentarial tradition.

Other points of interest
The Tàixuán’s reception across the centuries has been mixed: substantial admirers (Lù Jì, Fàn Wàng, Sīmǎ Guāng, Sū Shì 蘇軾, Zhū Xī 朱熹 in some moods) have placed it nearly alongside the Yìjīng; substantial critics (Yáng Xióng’s own contemporaries, including Liú Xīn 劉歆 who reportedly ridiculed it as material for sealing-jars; Hán Yù 韓愈; the more orthodox Sòng Neo-Confucians) have dismissed it as eccentric. The Sìkù editors’ classification in the shùshù sub-category effectively endorses an intermediate position: the work is not a Yìjīng-equal canonical work but is a substantive cosmological-numerological treatise worth preserving.
