POMERIUS, JULIANUS: Gallican presbyter of Moorish descent; d. about 490. He is said by Cyprian to have been the teacher of famous Cæsarius of Arles (q.v.), and according to the spurious addition to Gennadius' De vir. ill. (xcviii.) and Isidore's De scriptoribus ecclesiasticis (xv.), he wrote a dialogue De anim natura (or De natura anim et qualitate ejus) in eight books and a treatise De vita contemplativa (or De contemptu mundi) in three books. The first book of the latter work (MPL, lix. 415-520) treats of the value of the contemplative life, the second of the active life of the Christian, and the third of vices and virtues. The entire works are full of the spirit of Augustine. The similarity of the latter treatise to the eschatological meditations of St. Julian, bishop of Toledo, early led to Julian's identification with Pomerius, who flourished fully two centuries before him. Julian, a convert from Judaism, was archbishop from Jan. 29, 680, to Mar. 8, 690, and was zealous in defending and extending the faith and reformation of the clergy, at the same time maintaining a firm attitude toward Benedict II. when the pope criticized his creed. His apology addressed to Benedict, together with some of his other works, has been lost; but his Prognosticorum futuri seculi libri tres (Leipsic, 1535); De demonstratione sext tatis (Heidelberg, 1532); and Historia Wamb regis Toletani (MPL, xcvi.) are extant. He probably took part in the final redaction of the old Spanish liturgy and of the Visigothic canon law.
