caption: The image shows a drawing of a man with a beard and mustache, holding a book in one hand and a pen in the other. His face is clearly visible, with a strong jawline and a determined expression. His hair is neatly combed and his eyes are focused on something in the distance. He is wearing a long robe with a high collar and a belt around his waist. His hands are clasped in front of him, and his posture is upright and dignified.
