Adriaen van de Velde – Animals near a Building Part 1 National Gallery UK

The picture has something of this: cavalry, mammal, seated, mare, farm, horse, livestock, mustang, two, stallion, agriculture, stable, foal, equestrian, pasture, racehorse, outdoors.
Perhaps it’s a painting of a brown horse standing next to a herd of white cows in a field with a barn and clouds in the sky in the background.
