Rome, Religion, and Christian Emperors

The controversy over the altar of Victory shows how pagans and Christians expressed competing ideas on the public role of religion in an increasingly Christian empire. In 382, Gratian revoked funding from the Roman state priesthoods and removed the altar from the Senate house. Following Gratian’s death in 383, the Senate appealed to his brother, Valentinian II, through the urban prefect, Symmachus, whose communiqué was successfully countered by Ambrose of Milan. Recent scholarship has favoured Symmachus’ account, which it sees as an appeal for religious tolerance, and argued that the affair was decided by the power politics of a child emperor’s unstable court. In response, this chapter argues that Symmachus was actually trying to exclude the emperor’s Christianity from public decision-making. All religions may, for Symmachus, lead to God, but the old cults are Rome’s divinely appointed defence, as well as the bond between Senate and emperors. Ambrose put Valentinian’s duty to God at the heart of his appeal. Ambrose’s Senate contained many Christians, and Ambrose was bound to resist an emperor who endorsed pagan sacrifices (the closest either work comes to explicit political gamesmanship). Together, their works show how malleable Rome’s public religion still was, more than seventy years after Constantine embraced Christianity.
