Xún Shuǎng 荀爽
Zì Címíng 慈明. Late Eastern Hàn 東漢 statesman and Yì master, native of Yǐngyīn 潁陰 (modern Xǔchāng 許昌, Hénán). Of the great Yǐngchuān Xún 潁川荀 family, ancestor of the Wèi-Jìn Xún clan that produced Xún Yù 荀彧, Xún Yōu 荀攸, and others. Sīkōng 司空 (“Minister of Works”) under the brief regime of Dǒng Zhuó 董卓 in 189; died in office. The standard biographical source is Hòu Hànshū (juan 62).
His Zhōuyì zhù belongs to the 費直 Fèi Zhí ancient-script (gǔwén 古文) line of Yì transmission — the lineage that fed into 鄭玄 Zhèng Xuán and 王弼 Wáng Bì — and is characterised by careful analysis of line-position (上下位 shàngxià wèi) and hexagram-virtue (剛柔 gāng-róu). The commentary is lost as an independent work but survives in extensive citation in 李鼎祚 Lǐ Dǐngzuò’s Zhōuyì jíjiě (KR1a0008); the Sìkù tiyao judges Xún’s method to be already “approaching Wáng’s commentarial method” by removing much of the Mèng-Jīng xiàngshù apparatus.
