Three Hunters in a Rocky Landscape Sawrey Gilpin (1733-1807)

The picture has something of this: cavalry, mammal, horse, mare, two, farm, seated, mustang, livestock, racehorse, stallion, foal, people, equine, pasture, equestrian, motion, group.
Perhaps it’s a painting of two horses and a foal standing in a wooded area with a rocky cliff in the background and another horse in the foreground.
