The Prophet Abdias (Obadiah) and the Libyan Sibyl Pinturicchio (Bernardino di Betto) (c.1452-1513)

The picture has something of this: saint, fresco, book, god, church, holy, ancient, aura, chapel, Gospel, antique, sacred, spirituality, prayer, belief.
Perhaps it’s a painting on the side of a building with a man and a woman standing next to each other and a banner in the middle of the painting.
