Probably born in Rome, he was notarius under Emperor Valentinian I when, in 365, he was sent to Africa to guarantee the loyalty of that province during the usurpation of Procopius, who had rebelled against the eastern Emperor Valens.
Later he is attested as Praetorian prefect of Italy in 385. Putting Neoterius in charge of the Italian prefecture, Theodosius I wanted to support the young and inexperienced Emperor Valentinian II from the influence of the Western usurper Magnus Maximus.[1] Neoterius is probably to be identified with the prefect who wanted to give the basilica Portiana of Milan to the Arians but who was opposed by the Nicene bishop Ambrose.
He knew Quintus Aurelius Symmachus, with whom he exchanged letters (he is the addressee of the letters 38-46 by Symmachus); according to these letters, Neoterius was alive in 393 and maybe in 398.
