A View of the Serpentine, Kensington Gardens John Martin (1789-1854)

The picture has something of this: tree, landscape, grass, field, nature, summer, countryside, sunset, outdoors, dawn, country, sky, fog, rural, farm, agriculture, fair weather, sepia.
Perhaps it’s a painting of cows grazing in a field next to a body of water with trees in the foreground and a sky with clouds in the background.
