caption: The image shows a painting of a group of men in a room, with one of them holding a knife in his hand. The painting is believed to be a representation of the martyrdom of St. John the Baptist, as depicted in the fresco by Giotto di Bondone. The men in the painting are wearing traditional clothing and appear to be in a state of distress, with some of them looking downcast and others looking up in fear. The background of the painting is a deep blue, with a few stars twinkling in the night sky.
