caption: The image shows an open book with a painting of a man on horseback in front of a castle, surrounded by a group of people and horses. The painting is accompanied by text, likely from a medieval manuscript, and the man on the horse is wearing a long coat and a hat, and is holding a sword in his right hand. The castle in the background is tall and imposing, with a red roof and a large gate. The people in the painting are dressed in medieval clothing and are engaged in a fierce battle, with some of them brandishing swords and shields.
