On The Move Józef Brandt (1841-1915)

The picture has something of this: people, group, mammal, many, camel, cavalry, man, wear, seated, veil, transportation system, vehicle, woman, group together, herder, military, child, festival, skirmish.
Perhaps it’s a painting of a group of people riding on the backs of horses next to a body of water with a horse drawn carriage in the foreground.
