caption: The image shows an open book with a drawing of a man on a horse in a field, surrounded by trees, houses, and a body of water. The book is believed to be from the 15th century, and the text on the page is likely a description of the scene. The man on the horse is wearing a long coat and a hat, and is holding a staff in one hand and a book in the other. The trees in the background are lush and green, and there is a small pond in the foreground. The sky is a deep blue, with a few white clouds scattered across it.
