EUSEBIUS, bishop of Vercelli (d. 371), a strong opponent of Arianism, was with St. Augustine, the first Western bishop to unite with his clergy in adopting a strict monastic life after the Eastern model (see Ambrose, Ep. 63 ad V ercellenses, s. 66) . The legend that he was stoned to death by the Arians was probably invented. His three extant letters are in Migne Patrol. Lat. vol. 12.
