Jean-Baptiste Camille Corot – Cows in a Marshy Landscape Part 4 National Gallery UK

The picture has something of this: mammal, cattle, livestock, outdoors, agriculture, cavalry, landscape, cow, tree, water, farm, grass, cropland, pastoral, daylight, countryside, seated, grassland.
Perhaps it’s a painting of a couple of cows in a field next to a body of water with trees and a man standing next to one of the cows.
