caption: The image shows a painting of a man riding a horse in a field, with a frame around it. The man is wearing a long robe and a hat, and is holding a staff in one hand and a book in the other. The horse is galloping forward, its mane and tail flowing in the wind. The field is lush and green, with trees and shrubs in the background. The sky is a deep blue, and the sun is setting in the distance.
