Repentance of St. Peter Guido Reni (1575-1642)

The picture has something of this: people, portrait, dog, canine, mammal, facial hair, facial expression, Renaissance, pet, saint, baby, indoors, sculpture, studio.
Perhaps it’s a close up of a painting of a man with a long white beard wearing a blue shirt and a yellow shawl with his hands folded over his chest.
