caption: The image shows a mosaic of St. John the Baptist, a man with a beard and a sword in his hand, standing in front of a wall with text written on it. He is wearing a white robe with a blue sash and a golden halo around his head. His face is stern and determined, and his eyes are focused on something in the distance. His hair is long and dark, and he has a halo of light around his forehead. The text on the wall is written in a golden font and is surrounded by a golden border.
