Magnasco, Alessandro Spera, Clemente – Banditti at Res. 1710 Hermitage ~ part 08

The picture has something of this: architecture, ancient, building, sculpture, people, group, bedrock, fountain, column, cavalry, city, monument, tower, outdoors, temple.
Perhaps it’s a painting of a group of people standing in front of a building with columns and people on the other side of the building.
