Werff, Pieter van der – De jonge Hercules met de slangen, 1700 - 1722 Rijksmuseum: part 1

The picture has something of this: nude, people, two, woman, man, reclining, shirtless, portrait, water, light, girl, son, naked, Renaissance, god, sculpture.
Perhaps it’s a painting of a naked boy sitting on a bed with a snake in his hand.
