Equestrian Portrait of Carlo di Borbone Francesco Liani (1712-1780)

The picture has something of this: cavalry, seated, people, lid, man, wear, mammal, cowman, veil, saddle, cowboy, competition, courage, horse, rider, sword.
Perhaps it’s a painting of a man riding on the back of a brown horse in front of a group of men on horseback in a wooded area with a cloudy sky.
