caption: The image shows an engraving of a man with a beard and a book in his hand. He has a serious expression on his face and his eyes are focused intently on something in the distance. His hair is neatly combed and his clothing is plain and unadorned. He is wearing a white robe with a black collar and cuffs, and his hands are clasped in front of him. The book he is holding is open to a page with text written on it.
