piazzetta7 Giovanni Battista Piazzetta (1682-1754)

The picture has something of this: people, portrait, man, facial hair, mustache, shirtless, son, nude, music, god, wear, facial expression, affection, woman, profile.
Perhaps it’s a painting of a man with long hair and no shirt holding a knife in his right hand and looking up at something on the other side of his head.
