Augustus, Caesar's heir and Rome's first emperor, built a vast triumphal monument on the Greek coast at Actium, overlooking the scene of his decisive sea-battle against Antony and Egypt; the bronze beaks of captured Egyptian warships projected from its seaward wall. Imperial iconography increasingly identified Emperors with the gods, starting with the Augustan reinvention of Rome as a virtual monarchy (the principate). Sculpted panels on the arch of Titus (built by Domitian) celebrate Titus' and Vespasian's joint triumph over the Jews after the siege of Jerusalem, with a triumphal procession of captives and treasures seized from the temple of Jerusalem – some of which funded the building of the Colosseum. Another panel shows the funeral and apotheosis of the deified Titus. Prior to this, the senate voted Titus a triple-arch at the Circus Maximus to celebrate or commemorate the same victory or triumph.
