When the Roman emperor Constantine marched on Rome in October of 312 CE and defeated Maxentius at the famous Battle of the Milvian Bridge, he had to have a big parade called a triumph, which also necessitated the construction of a triumphal arch. Constantine might have been in a bit of a hurry, however, or perhaps he was just frugal, so he pillaged imperial reliefs from the monuments of earlier emperors such as Hadrian, Trajan, and Marcus Aurelius. This is one of the large panels, this one from the reign of Trajan. Here, a winged victory figure places a crown of laurel on Trajan’s head.
