This refusal almost cost Orestes his life. Nitrian monks came from the desert and instigated a riot against Orestes among the population of Alexandria. These monks had resorted to violence 15 years before, during a controversy between Theophilus (Cyril's uncle) and the "Tall Brothers"; the monks assaulted Orestes and accused him of being a pagan. Orestes rejected the accusations, showing that he had been baptised by the Archbishop of Constantinople. A monk named Ammonius threw a stone hitting Orestes in the head. The prefect had Ammonius tortured to death, whereupon the Patriarch honored him as a martyr. However, according to Scholasticus, the Christian community displayed a general lack of enthusiasm for Ammonius's case for martyrdom. The prefect then wrote to the emperor Theodosius II, as did Cyril.
