Canaletto (Venice 1697-1768) – View of the Arch of Constantine with the Colosseum (82x122 cm) 1742-45 J. Paul Getty Museum

The picture has something of this: architecture, building, city, arch, monument, sculpture, column, landmark, ancient, town, outdoors, assembly, sky, daylight, street.
Perhaps it’s a painting of a group of people standing in front of a building with an arch in the middle of the picture and people standing on the other side of the building.
