Xiè Zhēn 謝榛 (1495–1575), zì Màoqín 茂秦, hào Sìmíng shānrén 四溟山人, of Línqīng 臨清 (Shāndōng). A bùyī (commoner without examination credentials) — blind in one eye and remarkable for it — who was nonetheless the founding theoretical voice of the Hòu Qī Zǐ literary society: he originated both the Sānyào (Three Essentials of Poetry) doctrine and the survey of Táng poets that became the Seven-Masters’ programme. After a falling-out with Lǐ Pānlóng, the LǐWáng circle expelled him from the canonical Seven-Masters lists. He spent his later years at the courts of various Míng princes; the Prince of Zhào famously presented his concubine to Xiè as in the Jiāng Kuí / XiǎoHóng story. He was instrumental in rescuing Lú Nán 盧柟 (cf. KR4e0217) from prison — one of the most-cited cases of Míng commoner-poet qìyì (chivalric integrity). His collection is the Sìmíng jí KR4e0216; his separate critical work Shījiā zhíshuō is Sìkù-recorded under shīwénpíng. CBDB 34735.
