F?te Champ?tre, c1730. This painting was originally attributed to Jean Baptiste Joseph Pater, an artist who specialized in idealized park scenes with amorous couples, known as f?tes champ?tres, a category of painting associated with the early 18th-century master Jean-Antoine Watteau (1684-1721). Recent research has indicated that it is more likely by Bonaventure de Bar, a follower of Watteau.
