Although this is an Assyrian relief from the 9th century BC, it displays features later familiar in Roman siegecraft. The walled town has crenellated battlements (pinnae). The wheeled siege engine resembles a later Roman vīnea: it is mobile, likely covered with crātis, i.e. wickerwork screening), and fitted with a battering ram (ariēs). There are also mobile siege towers (turrēs ambulātōriae) from which archers fire at the defenders. The damaged walls (moenia) suggest the assault is succeeding.
