John and David Pinturicchio (Bernardino di Betto) (c.1452-1513)

The picture has something of this: saint, fresco, ancient, wall, god, mural, church, aura, holy, spirituality, book, symbol, antique, text, religious belief.
Perhaps it’s a painting on the side of a building with a woman and a man sitting next to each other and a snake in the middle of the painting.
