caption: The image shows a painting of a man riding on the back of a horse, with a human face in the center of the painting. 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 has a determined expression on his face, and his eyes are focused on something in the distance. The horse is galloping forward, its mane and tail flowing in the wind. The background is a deep blue sky with white clouds, and the painting is framed in a golden border.
