Jupiter (disguised as Diana) seducing Callisto Giuseppe Bossi (1777-1815)

The picture has something of this: nude, people, woman, portrait, girl, naked, baby, water, child, reclining, barefoot, cupid, Renaissance, tree, river.
Perhaps it’s a painting of a naked man and a woman sitting next to each other in a wooded area, one of the men has his arm around the woman’s neck.
