汤若望 / Johann Adam Schall von Bell

Johann Adam Schall von Bell 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 [[Jesuits|Jesuit]] figure who carried the calendar-science branch of [[ChongzhenLishu|《崇祯历书》]] across the Ming-Qing transition. The episode says he protected the printing blocks, later presented the material to the Shunzhi court as Western calendar knowledge, and became important in the Qing astronomical bureaucracy.

In the source, Schall is not only a technical specialist. He shows how [[CalendarReformLegitimacy|calendar reform]] could become a route into state power, because accurate eclipse prediction and calendar calculation mattered to imperial authority. His career also shows why missionary knowledge was politically vulnerable: usefulness could create access, but foreign religious affiliation could become a charge.

The later [[YangGuangxian|杨光先]] case makes Schall’s page a conflict node. The episode links his imprisonment, later release, and death to a broader struggle over whether foreign calendar experts could be tolerated inside Chinese state institutions.
