Capriccio with sarcophagus, temple ruins and figures among them Giovanni Paolo Panini (1691-1765)

The picture has something of this: people, temple, group, bedrock, sculpture, man, ancient, architecture, building, god, gold, monument.
Perhaps it’s a painting of a man standing next to a group of people near a body of water with columns in the background and a man on a horse in the foreground.
