caption: The image shows a painting of a man with a long beard and a cross on his chest, holding a book in his hand. His face is clearly visible, with a strong jawline and a determined expression. His eyes are focused on something in the distance, and his hands are clasped in front of him. He is wearing a white robe with a blue sash and a golden halo around his head. His hair is long and dark, and he has a halo of light around his forehead.
