Loo, Jacob van – Liefdespaar, 1650-1660 Rijksmuseum: part 3

The picture has something of this: nude, Renaissance, shirtless, saint, people, sculpture, man, two, baroque, god, son, reclining, woman, kneeling.
Perhaps it’s a painting of a naked man and a naked woman in a bathrobe, one of which is brushing the hair of another man’s head.
