caption: The image shows a black and white drawing of a man riding a horse, which is believed to be a representation of the Mayan civilization. The man is wearing a long robe and a hat, and is holding a staff in one hand and a book in the other. He is standing in a field of tall grass, with a bright blue sky and white clouds in the background. The horse is galloping forward, its mane and tail flowing in the wind, and its eyes are focused on something in the distance.
