Legend of St Francis 21. Apparition to Fra Agostino and to Bishop Guido of Arezzo Giotto di Bondone (1266-1337)

The picture has something of this: people, saint, fresco, interior, Gothic, mosaic, decoration, traditional, Renaissance, architecture, church, ancient, god, culture.
Perhaps it’s a painting on the wall of a building with a painting of a man sitting on a bed next to another man and another man standing next to him.
