Dù Wǎn 杜綰
Northern-Sòng / Southern-Sòng transitional stone-connoisseur and pǔlù author, zì Jìyáng 季揚, hào Yúnlín jūshì 雲林居士. Native of Shānyīn 山陰 (Shàoxīng, Zhèjiāng). Grandson of the famous Northern-Sòng prime minister Dù Yǎn 杜衍 (978–1057; zǎixiàng 1044–1045) and great-great-grandson (via Dù Yǎn’s adoptive lineage) of the High-Tang poet Dù Fǔ 杜甫 — making him heir to one of the most famous literary-and-official families in Chinese history. The Kǒng Chuán 孔傳 preface to his Yúnlín shípǔ claims this Dù Fǔ descent and uses the poet’s “fish-and-dragons-tumbled-down-into-the-ditch-and-turned-to-stone” couplet as a model for Dù Wǎn’s stone-connoisseurship; the descent is plausible but the specific Dù Fǔ couplet is anachronistic to the supposed Hu-nan setting (a Sìkù editor-criticism).
Dù Wǎn’s fl. falls around the Jìngkāng catastrophe and the early Shàoxīng period — the Kǒng Chuán preface is dated Shàoxīng guǐchǒu (1133), giving the terminus ante quem of the Yúnlín shípǔ 雲林石譜 (KR3i0018). His one surviving work, the Yúnlín shípǔ in three juàn (one hundred sixteen varieties of decorative-stone), is the foundational text of Chinese stone-connoisseurship literature — the source of subsequent treatises in the YuánMíngQīng period — and one of the earliest systematic surveys of Chinese mineralogy by region.
