Wāng Dàyuān 汪大淵 (fl. 1330–1351), zì Huànzhāng 煥章; native of Nánchāng 南昌 in Jiāngxī. Yuán-period traveller and yújì author. Otherwise biographically undocumented. From Quánzhōu (the largest port in the world at the time) made two extended sea-voyages: the first beginning in Zhìshùn 1 (1330), the second in Zhìyuán 3 (1337), each lasting several years. The voyages took him across maritime Southeast Asia, the Indian coast, Sri Lanka, the Persian Gulf, the Arabian Sea, and possibly the East African coast. On the basis of his personal observations he composed the Dǎoyí zhìlüè 島夷誌略 (KR2k0142) — the principal mid-fourteenth-century Chinese-language documentary monograph on the Indian-Ocean trading world, prefaced by Zhāng Zhù 張翥 and Wú Jiàn 吳鑒 in Zhìzhèng (the Wú Jiàn Zhìzhèng jǐchǒu / 1349 preface dates the appended publication of the work in Wú’s Qīngyuán xùzhì). The work is unique among pre-Míng Chinese maritime monographs in being based on direct personal observation rather than merchant testimony. CBDB id 103642.
