caption: The image shows an open book with a drawing of a man on horseback, surrounded by a group of people, a house, and other objects. The book is believed to be from the book of hours, and the drawing is likely depicting a scene from a medieval manuscript. The man on the horseback is wearing a long coat and a hat, and is holding a sword in one hand and a shield in the other. The house in the background is a two-story structure with a red roof and a chimney. The other objects in the image include a castle, a tree, and a bird perched on a branch.
