The Sultan of Morocco and his Entourage Ferdinand Victor Eugène Delacroix (1798-1863)

The picture has something of this: people, group, cavalry, man, woman, many, veil, wear, military, seated, weapon, transportation system, mammal, camel, war.
Perhaps it’s a painting of a man riding on the back of a horse in front of a crowd of people and a man holding an umbrella over his head.
