Cossacks near mountain stream Franz Roubaix (1856-1928)

The picture has something of this: people, cavalry, desert, seated, mammal, man, landscape, woman, water, mountain, river, two, child, transportation system, recreation, camel, lid.
Perhaps it’s a painting of two men on horseback crossing a stream in a mountainous area with rocks and trees on either side of the stream, while another man is riding a horse.
