caption: The image shows a black and white drawing of a man in a cloak, believed to be Leonardo da Vinci's depiction of Saint John the Baptist. The man is depicted with a solemn expression, wearing a long robe and a crown of thorns on his head. His hands are clasped in prayer and his eyes are closed, as if in deep contemplation. His hair is long and wavy, and his face is framed by a halo of light. The background is a deep blue, giving the image a sense of solemnity and reverence.
