caption: The image shows a painting of a man with a long beard and a cross on his head, 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 hair is neatly combed. He is wearing a white robe with a blue sash, and a golden halo around his head. The background of the painting is a deep blue, and the text on the book is written in a golden font.
