南怀仁
The Shunzhi Emperor died in 1661 and Schall von Bell's position started to erode. In 1664 he was challenged by Yang Guangxian and the Muslim astronomers, who accused him of planning a rebellion and of having wilfully miscalculated time and place of a funeral and in that way contributed to the death of Consort Donggo. Schall von Bell and other Jesuits, Ferdinand Verbiest included, were imprisoned. Schall von Bell had a stroke in prison. At trial, Verbiest spoke in his defense, but all were condemned to death. However, after an earthquake, the Jesuits were pardoned and only five Chinese Christians working in the astronomical office were executed. The Jesuits were exiled to Macau. Schall von Bell died within one year of his release. He was buried in the Jesuits' Zhalan Cemetery in Beijing.
