Verboeckhoven Eugene Joseph A White Stallion In A Landscape Eugene Joseph Verboeckhoven (1799-1881)

The picture has something of this: cavalry, mammal, mare, animal, farm, grass, pasture, horse, livestock, rural, field, stallion, seated, equine, hayfield, grassland, nature, outdoors, mane.
Perhaps it’s a painting of a white horse standing on a dirt ground next to a body of water and a man in a boat on the other side of the water.
