The present collection was written to commemorate the third centenary of the death of the Portuguese Jesuit, Tomás Pereira (1645–1708). Dealing with some of the most decisive and controversial moments in the history of the Jesuit mission in China during the Kangxi era (1662–1722), these essays were produced by an international team of scholars and cover a wide range of topics that reflect a permanent academic interest, in Europe and America as well as in China, in the history of the Catholic mission in China, Sino-Russian diplomacy, the history of Western science and music in China, intercultural history, and history of art.While the names of such missionaries as Matteo Ricci, Adam Schall and Ferdinand Verbiest are well known, Pereira has been relatively neglected, and this volume seeks to redress that imbalance. Pereira was important as a musician and diplomat and was closer to the Kangxi emperor than any other Westerner, something that enabled him to exert considerable influence for the protection of the Chinese Christians and also to further the interests of Portugal in China. However, towards the end of his life he saw his efforts undermined by the damaging consequences of the papal legation to China led by Charles-Thomas Maillard de Tournon.
