This publication is the fourth monograph on an 18th-century artist published in the series “L’Art français” directed by Georges Wildenstein. Jean-Baptiste Pater (1695–1736) was a close friend and student of Watteau, as well as a painter of fêtes galantes whose use of seductive colors contributed to his success. The catalogue examines 616 paintings, all illustrated, which are grouped by themes such as theater, country pleasures, games, military scenes, portraits, and landscapes.
