Sorry if this have been brought up before.
Septimius Severus's triumphal arch in Leptis Magna (Libya) is an arcus
quadrifons, i.e. a square with an arch in each side. I don't know whether
such arches were normal or rare; another one is one that is tought to have
been erected by Constantine, but for no known purposes.
