View of the Sbocco della Cloaca Massima, Rome Ettore Roesler Franz (1845-1907)

The picture has something of this: water, people, group, river, man, architecture, transportation system, vehicle, house, building, outdoors, watercraft, lake, seashore, tree.
Perhaps it’s a painting of a man in a boat in a body of water with a tower in the background and people.
