Keyser, Thomas de – Pieter Schout (1640-69). Drost van Hagestein, 1660 Rijksmuseum: part 2

The picture has something of this: cavalry, seated, mammal, people, equestrian, cowman, two, cowboy hat, rider, man, horse, lid, wear, transportation system, herder, saddle, action energy, cowboy.
Perhaps it’s a painting of a man riding on the back of a black horse in a field with a hill in the background and a cloudy sky.
