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.Stephen Williams, Gerard Friell, John Gerard Paul Friell, Theodosius: the empire at bay, Routledge, 1994, , p. 42. 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.
