A Grey Arab Stallion In A Wooded Landscape Jacques-Laurent Agasse (1767-1849)

The picture has something of this: cavalry, mammal, mare, horse, two, equestrian, equine, pony, stallion, livestock, animal, seated, farm, mustang, wildlife, cattle, mane, goat.
Perhaps it’s a painting of a white horse galloping in a wooded area with a tree in the foreground and a bird on the far side of the painting.
