Hercules and Deianira, with the dying Centar Nessus Sebastiano Ricci (1659-1734)

The picture has something of this: nude, people, man, Renaissance, shirtless, group, woman, baroque, reclining, two, three, saint, nymph, son.
Perhaps it’s a painting of two men and a woman in a wooded area, one of which is holding a staff and the other.
