Sū Yìjiǎn 蘇易簡
Northern-Sòng official, jìnshì of Tàipíngxīngguó 5 (980), the youngest zhuàngyuán (top jìnshì) of his generation — he passed first in the jìnshì at age twenty-two. Native of Tóngshān 銅山, Zǐzhōu 梓州 (modern Sìchuān). Zì Tàijiǎn 太簡.
His Sòng career was distinguished but short. He rose through Hànlín-academy offices to cānzhī zhèngshì 參知政事 (vice-grand-councillor) under Tàizōng. Was demoted out of the central government for his association with the partisan struggles of the late Tàizōng court, exited to the prefect-ship of Dèngzhōu 鄧州, then transferred to Chénzhōu 陳州, where he died in office in 996, age thirty-eight. His official biography is in Sòngshǐ 266.
CBDB lists his lifedates as 958–996; the Sìkù catalog meta gives 957–995. The CBDB figures (followed here) are consistent with Sòngshǐ 266 and with the dating of his other works. Both sets are within one year of each other and likely reflect different inclusive-or-exclusive conventions on the guǎnniǎn year.
His best-known works are the Wénfáng sìpǔ 文房四譜 (KR3i0002) of 986, the first systematic monograph on the Four Treasures of the Study (brush, ink-stone, paper, ink) — a foundational text of the pǔlù 譜錄 genre; and the Xù Hànlín zhì 續翰林志, a continuation of Lǐ Zhào’s 李肇 Tang-period institutional history of the Hànlín Academy, preserved in the Sòng Hànyuàn qúnshū anthology.
