caption: The image shows an engraving of a man with a beard and a book in his hand, standing in front of a building. He is wearing a long robe and has a halo of light around his head. His facial features are detailed and his eyes are closed, giving him a peaceful and serene look. The building behind him is tall and imposing, with a few windows and a door. The sky is a deep blue, and the sun is setting in the background, casting a warm orange glow over the scene.
