Hilarius
(1) A Christian writer born at Poitiers of pagan parents. He was elected bishop of his native place in A.D. 350. In 356, his strong polemics against the Arians led to his banishment by Constantine, who allowed him, however, to return from Phrygia, the place of his exile, and resume his office. He died in 368. His works consist of polemics against the Arians and addresses to the emperor. The best edition of his works is that of Coutant (2d ed. 1844-45). For his life see Cazenove's St. Hilary of Poitiers (1883).
(2) Bishop of Arelaté (Arles) from A.D. 429 to 449. He wrote the life of Honoratus and a few other works.
