caption: The image shows an open book with a painting of a man on a horse, surrounded by a group of people. The painting is accompanied by text, likely from a medieval manuscript. 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 people around him are dressed in medieval clothing and appear to be engaged in conversation. The background of the painting is a landscape of rolling hills and a bright blue sky.
