caption: The image shows Rembrandt van Rijn's self-portrait of a man wearing a hat and reading a book. The man is depicted in a realistic style, with a serious expression on his face and his hands resting on the book. He is wearing a long-sleeved shirt and a hat, and his eyes are focused on the pages of the book in front of him. The background is a muted grey, and the painting is framed in a simple black frame.
