Diana and Callisto Titian (Tiziano Vecellio) (1488/90-1576)

The picture has something of this: baroque, Renaissance, saint, nude, reclining, sculpture, god, people, man, cavalry, allegory, woman, nymph, ancient, group.
Perhaps it’s a painting of a group of naked people in a wooded area with a fountain in the foreground and a man in the middle of the painting.
