caption: The image shows a portrait of Guittone d'arezzo, a man with a wreath on his head, holding a book in his hand. At the bottom of the image there is some text which reads "Guittone di Marezzo". He is wearing a white robe and a black hat, and has a serious expression on his face. His hair is dark and his eyes are focused intently on something in the distance. He is standing in a field of tall grass, with a bright blue sky and white clouds in the background.
