Ricci Sebastiano (1659 Belluno – 1734 Venice) – Triumph of Venus (160x211 cm) c.1713 J. Paul Getty Museum

The picture has something of this: nude, people, group, woman, water, man, Renaissance, child, girl, nymph, sea, vacation, cupid, recreation, two, reclining.
Perhaps it’s a painting of a group of men and women in a body of water with a man on top of the man in the middle of the painting.
