Turner Joseph Mallord William Rainbow. A view on the Rhine from Dunkholder Vineyard of Osterspey Joseph Mallord William Turner (1775-1851)

The picture has something of this: landscape, water, daylight, river, people, mountain, vehicle, lake, scenic, outdoors, motion, reflection, environment, volcano, exploration.
Perhaps it’s a painting of a rainbow in the sky over a body of water with a group of people standing on the shore.
