caption: The image shows an open book with a page from a medieval manuscript featuring a man and a woman on a horse. The page is filled with text and pictures, and the man is wearing a long robe and a hat, while the woman is holding a staff in her right hand. The horse is standing on its hind legs, with its front paws raised in the air. The background of the page is a deep blue, with a few stars twinkling in the night sky.
