Career
Neoterius was appointed Praetorian prefect of the East between 380 and 381. Later he is attested as Praetorian prefect of Italy in 385. 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.
