Hillegaert, Pauwels van – Prins Frederik Hendrik te paard voor de vesting ’s-Hertogenbosch, 1629, 1632-1635 Rijksmuseum: part 4

The picture has something of this: cavalry, seated, mammal, equestrian, horse, two, people, action energy, saddle, lid, rider, woman, man, cowman, motion, sword, wear.
Perhaps it’s a painting of a man riding on the back of a white horse wearing a sombrero and a sombrero on top of his head.
