Wèi Wénkuí 魏文魁
Style name Yùshān 玉山. Commoner astronomer of Mánchéng 滿城 (Bǎodìng prefecture, Héběi). Birth and death years not securely recorded; certainly active at court from c. 1629 through 1635. CBDB c_personid 128113 (a homonym appears at 427463 with no dates).
The leading conservative astronomical opponent of the Jesuit-led Chóngzhēn lìshū 崇禎曆書 reform project of 1629–35. Through the patronage of his son Wèi Xiànglǔ 魏象乾 (active in capital memorial-bureau circles), Wèi Wénkuí was summoned to the court in the late Tiānqǐ / early Chóngzhēn period and authorised to establish a parallel Dōngjú 東局 (“Eastern Bureau”) for the Tōngjí jiālì 通濟嘉曆 — a rival calendrical reform programme intended to reconcile the inherited Dàtǒng with native cosmological principles, against the Xījú 西局 (“Western Bureau”) of Xú Guāngqǐ 徐光啟, Lǐ Tiānjīng 李天經, Schall, and Rho. The competition was decided empirically through a sequence of test eclipse predictions over 1629–34, in each of which the Xījú methods proved more accurate; the Dōngjú was wound up in 1635.
Wèi’s surviving theoretical writings — including KR3fb011 Lì cè in 5 juàn — defend the proposition that the ancient Chinese calendrical tradition already contains the resources needed for accurate computation, and that the Yuán Shòushí lì in particular needs refinement rather than replacement. He gives unusual prominence to Zǔ Chōngzhī 祖沖之 of the LiúSòng (Dàmíng lì 大明曆) as the great precursor of mathematical astronomy, and is sharply critical of Yī Xíng 一行 and the Sòng Confucians for letting the science decay. The polemical posture is exactly that against which Schall’s KR3fb013 Mínlì pùzhù jiěhuò is in part directed.
Despite his loss to the Jesuits at court, Wèi was a significant figure in the early-Qīng polemical tradition through Yáng Guāngxiān 楊光先 and other anti-Western voices, and the Sìkù compilers — at one remove — preserved his works as documentation of the controversy.
