The surrounding scene is an architectural capriccio, not a single known location but rather combining parts of known Roman buildings from several different locations=. To the left rear is a triumphal arch, with an inscription taken from the Arch of Trajan at Benevento, 130 miles southeast of Rome; its spandrel is decorated with a river god based on the Arch of Constantine, but unusually accompanied by a sheep and bull (for Aries and Taurus, denoting April and May).
