Horse called the Fire Clipper * David Klöcker Ehrenstråhl (1629-1698)

The picture has something of this: cavalry, mammal, horse, two, seated, mare, mane, side view, livestock, equestrian, pony, stallion, equine, farm, outdoors, wildlife, action energy.
Perhaps it’s a painting of a brown horse with a white spot on it’s face and tail, standing in a room with a gray wall behind it.
