Philastrius

Saint Philastrius (also Philaster or Filaster) Bishop of Brescia, was one of the bishops present at a synod held in Aquileia in 381. St. Augustine met him at Milan about 383, or perhaps a little later (St. Augustine, Ep. ccxxii). He composed a catalogue of heresies (Diversarum Hereseon Liber) about 384. He died before 397.
