A Bay Horse in a Field Edmund Bristow (1787-1876)

The picture has something of this: cavalry, horse, mammal, mare, stallion, seated, racehorse, equine, foal, mane, animal, mustang, farm, livestock, runner, equestrian, grassland, colt, two, chestnut.
Perhaps it’s a painting of a brown horse standing on a lush green field next to a field with trees and a blue sky with white clouds in the background.
