caption: The image shows a painting of a man in a green robe, believed to be St. John the Baptist, holding a book in his hands. He is wearing a long, dark robe with a high collar and a belt around his waist. His face is stern and his eyes are focused on something in the distance. His hands are clasped in front of him and his posture is upright and dignified. The background is a deep blue, with a few stars twinkling in the night sky.
