The Colosseum and other Monuments Giovanni Paolo Panini (1691-1765)

The picture has something of this: architecture, ancient, column, Colosseum, building, monument, city, archaeology, assembly, tower, amphitheater, sky, gladiator, ruin, landmark, empire, temple.
Perhaps it’s a painting of a roman colossion with a statue in the foreground and a statue of a man on a horse.
