caption: The image shows an open book with a black and white image of a man's face on it. The book is believed to be a bibl mazarine, a type of medieval manuscript, with text written on the paper. The man in the image has a serious expression on his face, and his eyes are focused intently on something in the distance. His hair is dark and his skin is a light shade of grey. He is wearing a white robe and a black hat, and he is holding a staff in one hand and a book in the other.
