Equestrian portrait of Henri de la Tour dAuvergne before Maastricht Adam Frans Van der Meulen (1632-1690)

The picture has something of this: cavalry, mammal, seated, people, two, man, horse, saddle, equestrian, herder, veil, transportation system, cowman, recreation, motion, woman, bridle, adventure.
Perhaps it’s a painting of a man riding on the back of a white horse in a wooded area with a river and town in the distance in the background.
