Bacchus and Ariadne Charles-Joseph Natoire (1700-1777)

The picture has something of this: people, nude, group, water, woman, recreation, man, tree, enjoyment, leisure, shirtless, girl, child, seashore, several.
Perhaps it’s a painting of a group of naked women in a wooded area with a man in the foreground and a man on the far side of the painting.
