caption: The image shows a portrait of a man with a long beard and a ruffled collar, holding a book in his hand. At the bottom of the paper, there is some text written. The man in the portrait has a serious expression on his face, and his eyes are focused intently on the book he is holding. His hair is dark and his beard is full and well-groomed. He is wearing a white robe with a black collar and a black shawl draped over his shoulders.
