caption: The image shows a relief of a man on a horse, carved onto a stone plaque. The man is wearing a long robe and a hat, and is holding a staff in his right hand. He is standing in a heroic pose, with his left arm outstretched and his right leg bent at the knee. The horse is galloping forward, its mane and tail flowing in the wind. The relief is detailed and lifelike, with the man's facial features and clothing clearly visible.
