Nonius belonged to the senatorial aristocracy, and was a Christian, even if he was a friend of Quintus Aurelius Symmachus.[1]
He was Praetorian prefect of Italy between 383 and 384 and then Consul in 397. In 383 Emperor Gratian died, and his half-brother Valentinian II become the only Emperor. He then decided for a change among the high officers, who had served under Gratian, with new men, more loyal to him. Atticus then succeeded the praetorian prefect Sextus Claudius Petronius Probus, but one year later he was succeeded by Vettius Agorius Praetextatus, and his office was called an "interregnum".
