John the Baptist Michelangelo Merisi da Caravaggio (1571-1610)

The picture has something of this: nude, people, woman, portrait, wear, girl, man, shirtless, model, dark, naked, sexy, position, son, light, erotic.
Perhaps it’s a close up of a painting of a man with a red cloth on his lap and a knife in his other hand and a tree in the background.
