Giuseppe Castiglione, S.J., was an Italian Jesuit brother and missionary in China, where he served as an artist at the imperial court of three Qing emperors – the Kangxi, Yongzheng and Qianlong emperors. He painted in a style that is a fusion of European and Chinese traditions.

The Qianlong Emperor, also known by his temple name Emperor Gaozong of Qing, personal name Hongli, was the fifth emperor of the Qing dynasty and the fourth Qing emperor to rule over China proper. He reigned officially from 1735 until his abdication in 1796, but retained ultimate power subsequently until his death in 1799, making him one of the longest-reigning monarchs in history as well as one of the longest-lived.
