Shěn Dù 沈度 (Sòng, fl. 1145–1147)
Disciple of Chén Yuān 陳淵. Studied under him “left and right for nearly twenty years” (per his own preface). After Chén’s death (1145), gathered the master’s yíwén — 514 surviving pieces — and arranged them into 22 juǎn, providing the xù in Shàoxīng 17 (1147). The Mòtáng xiānshēng wénjí KR4d0207 is the principal record of the Yáng Shí → Chén Yuān line of Lǐxué transmission and survived in this disciple-edited recension.
(A separate Míng-dynasty Shěn Dù 沈度, 1357–1434, the famous zhuàngyuán calligrapher, is unrelated and not the editor here.)
