caption: The image shows a black and white drawing of two men, one of whom is holding a harp, on the wall of a building. The man with the harp is wearing a long robe and has a halo of light around his head. He is standing in front of the other man, who is looking up at him with a contemplative expression. The wall behind them is decorated with intricate designs and symbols, and the ceiling of the building is visible at the top of the image.
