Ŭich’ŏn 義天 (1055–1101), the great Goryeo Korean Buddhist scholar-monk and prince — the fourth son of King Munjong 文宗 of Goryeo (r. 1046–1083). Posthumously Dàjué guóshī 大覺國師 (“Great-Awakening National Preceptor”). Took monastic vows at age 11 and devoted himself to Buddhist scholarship; became the principal Goryeo Buddhist scholar of his generation, with a particular emphasis on the Huáyán-Hwaeom doctrinal tradition.
In 1085–1086 he travelled to Northern Sòng China, where he studied at the Huìyīnsì 慧因寺 in Hángzhōu under 淨源 Jìngyuán — the centre of the Sòng Huáyán-school revival. His patronage of Jìngyuán’s Huìyīnsì project and his subsequent return to Korea with substantial Sòng Buddhist literature was the foundation of the Goryeo Buddhist textual heritage; the Huìyīnsì subsequently became known as the “Korean Master’s Monastery” (高麗師寺) in honor of Ŭich’ŏn.
Founded the Korean Cheontae 天台 (Tiantai) school as a separate doctrinal lineage in Goryeo Buddhism. Compiled the great Sin-pyeon Choseon Bulgyo Doseo Mongnok 新編諸宗教藏總錄 (“Newly Compiled Comprehensive Catalogue of the Various-Schools’ Doctrinal Treasury”) — the foundational catalogue of Korean Buddhist textual scholarship. His [[KR6e0134|Yuánzōng wén lèi 圓宗文類]] (X1015, 2 fasc.) is the present text.
He died in 1101, shortly after his return from China. His Hwaeom and Cheontae textual labors were the foundation of the great Goryeo Tripiṭaka Koreana canon-printing project.
