『関訂書』に見られる明代後期の中国・回回暦法研究について Late Ming treatises on Chinese and Islamic calendrical systems as seen in the Seki Teisyo
The Seki Teisyo (関訂書), a manuscript compiled by Seki Takakazu (関孝和) in 1686, is known to consist of 15 treatises which Seki extracted from an early Qing astronomical and astrological corpus, the Tianwen Dacheng Guankui Jiyao (天文大成管窺輯要). Containing a detailed account of the Shoushi Li (授時暦) as well as a comparative study of Chinese and Islamic calendrical systems, these treatises have drawn the attention not only of Seki but of modern historians. In this paper, I show that 14 of the 15 treatises Seki selected had been composed by a late Ming scholar, Zhou Shuxue (周述学), who discussed issues with Tang Shunzhi (唐順之). Their time predates the era in which the mathematical basis of the Shoushi Li was scrutinized and a new Chinese calendrical system was invented incorporating Western astronomical knowledge. I also mention some earlier works that Tang and Zhou could have consulted. Although Seki never knew the author of the treatises nor their background, his concern centered on themes that seem to have derived from one of those earlier works: the Liyuan (暦源).
