Zǔ Táizhī 祖台之 (late 4th century), zì Yuánchén 元辰, native of Fànyáng 范陽 Suìchéng 遒城. His biography stands in Jìn shū 75 (列傳 45). Of the Fànyáng Zǔ clan — the same lineage as the great early-medieval astronomer-mathematicians Zǔ Chōngzhī 祖沖之 (429–500) and Zǔ Gēng 祖暅 — he served on the staff of Sīmǎ Dàozǐ 司馬道子 (Prince of Kuàijī, dominant Eastern-Jìn courtier of the 380s–390s) as Cānjūn 參軍 and Zhōngshū láng 中書郎, eventually rising to Shàngshū 尚書 in the closing years of the Eastern Jìn. His official career thus spans roughly 380–410. He is credited in the Suí shū jīngjí zhì with a Zhìguài 志怪 (also styled Zhìguài lù 志怪錄, sometimes Zǔ Táizhī Zhìguài 祖台之志怪) in 2 juàn — a zhìguài collection now surviving only in fragments preserved in the standard Sòng léishū, and reconstructed in Lǔ Xùn’s Gǔ xiǎoshuō gōuchén. He has no CBDB id in the current dump. Within the Kanripo corpus he is the credited author of KR3l0163.
