was a bishop of Cemele, in the Maritime Alps, now in the archbishopric of Embrun. He belonged to the 5th century. He attended a synod at Riez in 439, signed the address of the Gallican bishops to Leo I in 451 (see Leonis M. Opp. 1, 998, 1110: sq.), and took sides with the monastery of Lerins, in 454, in its dispute with the bishops of the neighborhood. The year of his death is not known. He left twenty-nine Sermones, or Homilies, and an Epistola ad Monachos, which were published by Sirmond (Par. 1612) and Raynauld (Lugd. 1633). Raynauld's edition is given also in Migne, Patrolog. (Par. 1845), 52. Galland furnished an additional edition of Valerian, together with a Petrus. Chrysologus, in the Bibl. Max. Patr. (1774), c. 10. See Cave, Script. Eccl. Hist.
