caption: The image shows a painting of a man standing in front of a window, holding a stick in one hand and a book in the other. His face is visible, with a thoughtful expression and a gentle smile. He is wearing a white robe with a blue sash and a golden halo around his head. His hair is long and dark, and his eyes are looking off into the distance. The window behind him is open, letting in a soft light that illuminates the painting.
