Wú Sùgōng 吳肅公 (zì Yǔruò 雨若, hào Jiēnán lǎorén 街南老人; 1626 – c. 1699; native of Xuānchéng 宣城, Anhui) was an early-Qīng scholar of the Tóngchéng 桐城 school’s Anhui satellite, known for his classical commentaries and miscellaneous bǐjì. He was a contemporary and intellectual associate of Méi Wéndǐng 梅文鼎 and his Xuānchéng circle, the principal Anhui contributor to the integration of Western (Jesuit) astronomy with the classical tradition. Wú’s Tiānguān kǎoyì 天官考異 (KR3fa022) is a one-juǎn critical study of discrepancies between the canonical Tiānguān shū 天官書 of 司馬遷’s Shǐjì and the asterism inventory current in his own day.
