caption: The image shows a painting of a rocky landscape with a river in the foreground, painted by Joseph Mallord William Turner in 1797. The painting is composed of a variety of colors, including blues, greens, and yellows, and features a rocky cliff in the background. The river is winding its way through the landscape, with trees and shrubs dotting the banks. The sky is a deep blue, and the sun is setting in the distance, casting a warm orange glow over the scene.
