He was the last of the Western painters who worked for the Qianlong Emperor, together with Father Giuseppe Panzi.
The two painters replaced the more famous father Giuseppe Castiglione and Jean-Denis Attiret.
He was also in charge of the translations between Latin and Manchu for the diplomatic correspondence between Beijing and Saint Petersburg (Russia).
