The moon is shown as a small but intense semi circle of light emerging from cloud above the falls and reflected in the waters below. Turner applied a light tonal wash before working up the composition in colour. He used pen to suggest the wooded character of the steep banks and included a little more architecture than in other views of the Falls. Cooler tones dominate, appropriate for the moonlit scene. It is inscribed at the bottom left: Falls of the Rhine / 1841.
