the rainbow c1878-9 George Inness (1825-1894)

The picture has something of this: mammal, landscape, cattle, fog, cavalry, farm, agriculture, grassland, livestock, outdoors, cropland, dawn, sheep, tree, weather, daylight, storm, pastoral, cow.
Perhaps it’s a painting of a horse in a field with a rainbow in the sky above it and a cow laying down in the grass in the foreground.
