《崇祯历书》 / Chongzhen Lishu

《崇祯历书》 enters the wiki through EP259 与苗师傅漫谈徐光启：四百年前如何让人变聪明？ as the late-Ming calendar-reform project associated with [[XuGuangqi|徐光启]]. The episode presents it as a large compilation of European classical astronomy, mainly geocentric in structure, rather than as a simple arrival of modern heliocentrism.

The source uses the work to explain [[CalendarReformLegitimacy|calendar reform as legitimacy]]. Accurate eclipse prediction mattered because the calendar was tied to imperial order, Heaven, and the emperor’s symbolic stability. In this frame, astronomy is both technical calculation and political infrastructure.

The work also becomes a Ming-Qing transition object. The episode says [[JohannAdamSchallVonBell|汤若望]] preserved the printing blocks, later reworked or presented the material as Western calendar knowledge to the Qing court, and entered the astronomical bureaucracy. That continuity later becomes vulnerable in the [[YangGuangxian|杨光先]] controversy.
