Frequently asked questions

Orestes was the Augustal prefect of Egypt at the beginning of the 5th century, meaning the emperor's direct representative in Alexandria. The key point to remember is that he embodied Roman civil authority in a province crucial to the Empire's grain supply. A Christian, but attached to the separation of powers, he opposed Bishop Cyril, who sought to extend his influence over political affairs. His conflict with the bishop illustrates a tension typical of Late Antiquity: who holds true authority in a great city — the governor or the patriarch?

Anecdotes

As the imperial prefect of Alexandria, Orestes was one of the friends and protectors of the philosopher Hypatia, a scholar renowned for her teaching of mathematics and astronomy. Their friendship fueled the suspicions of Bishop Cyril's faction, which accused Hypatia of turning the prefect against the Church.

According to the historian Socrates of Constantinople, Orestes was nearly killed during a riot: a monk named Ammonius threw a stone that struck him on the head. The prefect had his attacker arrested and executed, which further inflamed the conflict with Cyril.

Orestes was a baptized Christian, yet he refused to submit to the bishop's growing authority over the civil affairs of the city. He insisted that, as the emperor's representative, the governance of Alexandria was his to exercise.

When Hypatia was savagely murdered by a mob in 415, the prefect sent a report to the emperor in Constantinople. But no serious punishment was imposed, and Orestes then disappears from the historical record.

The conflict between Orestes and Cyril illustrates a tension typical of late antiquity: who holds the true authority over a great city of the Empire — the imperial governor or the bishop?
