White Horse in Pasture Jacques-Laurent Agasse (1767-1849)

The picture has something of this: cavalry, mammal, horse, mare, seated, equine, mustang, animal, farm, stallion, livestock, equestrian, pony, two, outdoors, wildlife, pasture.
Perhaps it’s a painting of a white horse standing in front of a tree in a wooded area with cattle grazing on the other side of the tree in the foreground.
