Zhāng Xiànyì 張獻翼 (1534–1604), zì Yòuyú 幼于, was a late-Míng Yìjīng scholar and notorious literary eccentric from Kūnshān 崑山 (Sūzhōu 蘇州, modern Jiāngsū 江蘇); he later changed his name to Zhāng Mǐ 張敉. The Sìkù notice characterizes him as “loose and unrestrained, with strange words and conduct” (放誕不羈，言行詭異); he eventually died meeting bandits while sleeping in the open after a drinking bout — “perhaps suffering from mental illness,” as the editors charitably suggest.
Despite his erratic personal conduct, his early-career Yì-writings — produced when he was reading at Mount Shàngfāng 上方 in Kūnshān — are described by the Sìkù editors as plain, smoothly arranged, solid, and not given to extravagance. The Dú yì jì wén 讀易紀聞 (KR1a0101) is the principal surviving such work; it sets aside the LǎoZhuāng metaphysical and explicates ChéngZhū yìlǐ. Zhū Yízūn’s Jīngyì kǎo records five Yì works by him, of which only two — the Dú yì jì wén and a Dú yì yùn kǎo 讀易韻考 — survive. The Sìkù editors received the Dú yì yùn kǎo but found it grossly inadequate (“like a blind man speaking of black-and-white, like a deaf man discussing musical modes”) and demoted it to the catalog-only cún mù 存目 list. The Dú yì jì wén is not arranged passage by passage as a continuous commentary; rather, each remark is a separate aphoristic note (zhájì 劄記), without quoting the canonical text.
Zhāng was the elder brother of Zhāng Fèngyì 張鳳翼 (1527–1613, the Kūnqǔ playwright); the two together with their younger brother Zhāng Yányí 張燕翼 were known as the “Three Mr Zhāngs of Kūnshān.”
