Two Horses in a Landscape Nicolaes (Claes Pietersz.) Berchem (1620-1683)

The picture has something of this: mammal, cavalry, wildlife, two, animal, outdoors, nature, mare, seated, grass, wild, horse, farm, livestock, equine, mustang, countryside.
Perhaps it’s a painting of a horse and a foal standing in a wooded area with a castle in the distance and a bird flying in the sky.
