A Horse For Carrying Stones In Veules Ilya Repin (1844-1930)

The picture has something of this: outdoors, nature, sky, cavalry, water, mammal, summer, grass, rural, horse, fair weather, horizontal plane, sand, countryside, leisure, recreation, landscape.
Perhaps it’s a painting of a white horse with a saddle standing on a sandy beach next to a body of water with houses on the other side of the water.
