Screyer Adolf Arabian Horsemen Near A Watering Place Adolf Schreyer (1828-1899)

The picture has something of this: people, mammal, cavalry, seated, group, man, herder, many, cattle, wear, skirmish, transportation system, livestock, weapon, soldier, recreation.
Perhaps it’s a painting of a group of men on horses in a field next to a stream and a man on a horse on the other side of the painting.
