Sū Xùn 蘇遜, son of Sū Zhé 蘇轍 (1039–1112; see 蘇轍). Known almost exclusively for the supplementary notes (fùzhù 附註) attached to his father’s Gǔshǐ 古史 (KR2d0005); the Sìkù editors identified him as the author of these notes (which the old editions had carried anonymously) on the strength of Yè Dàqìng 葉大慶’s Kǎogǔ zhìyí 考古質疑. CBDB id 19181 (no dates). Otherwise unrecorded in the historical record beyond his father’s Luánchéng circle.
