caption: The image shows a painting of a man riding on the back of a white horse, with a dragon in the foreground and trees in the background. The man is believed to be Saint George, as depicted in the painting by Rembrandt van Rijn. The dragon is a mythical creature, with its wings spread wide and its mouth open in a roar. The sky is a deep blue, with stars twinkling in the night sky. The trees are lush and green, providing a peaceful backdrop to the scene.
