Polyphemus And The Nymph Galatea Annibale Carracci (1560-1609)

The picture has something of this: people, man, nude, shirtless, group, son, Renaissance, weapon, god, pain, two, mammal, warrior, kneeling, woman.
Perhaps it’s a painting of a man standing in front of a painting of a man holding a bag and another man standing next to him in front of him.
