He did not met his model but based the paintings on the works of his teacher, Louis Caravaque. In 1755-1757 he worked in Moscow frescoeing the Golovkin palace. Here he met prince Ivan Shuvalov who supported Antropov's works for the rest of his life. In 1757 - 1759 Antropov returned to Saint-Petersburg and learned art from court painter Pietro Rotari of Italy. Historians consider his portrait of A.M. Izmaylova to be a sort of a graduation work.
