生活在明代前中期的桑悅，在今天的學術論述中被認為是復古詩學思潮中的一員，而他為高棅《唐詩品彙》所作的序文，也成為討論後者成書和流傳的重要文獻。本文通過探討桑悅的生平、交遊、文集，將他放置在過去的山林-臺閣的對峙論述之外，揭示他不同於前七子的獨特的復古詩學：一方面，他不滿於流行詩風的限制，希望拓寬學習的對象，於是以「復古」為標榜，將學習的對象一路向上擴展到唐人三百家、魏晉古詩，直至《詩經》；另一方面，朱熹等理學家的學說浸潤他的思想的同時也浸潤著他的詩歌，於是詩文部分地變成了體道的工具，詩歌復古的過程也摻雜著求道的過程。這套觀念不是作為前七子等「復古派」的先鞭（復古派也不承認它），而是根據他所處社會階層的流行觀念、他能接觸到的出版物等得出的一種求變的反思。

Sang Yue (1447-1503), who lived in the early middle period of Ming Dynasty, was seen as one member of the critics advocating the revival of the ancient poetic. Also Sang’s two prefaces for Gao Bing’s (1350-1423) Tangshi pinhui provide fascinating material to the Chinese literature scholars in relation to this anthology’s publication and circulation. This paper examines Sang Yue’s life, companionship and his works, and further, explores his special theory of restoration poetry, which was historically and practically different from contemporary mainstream thought.
