Victorinus bishop OF PETTAU (Petavionensis), a town in ancient Pannonia, not of Poitiers, as Baromius states, lived about A.D. 290, and was an orator before he became a bishop. He was of Greek extraction, and was better acquainted with the Grecian than the Latin tongue. Of his works, a fragment, De Fabrica Mundi, was published by Cave (see below). Jerome says that Victorinus wrote commentaries on most of the books of the Old Test., and he is also credited with the authorship of a commentary on the Apocalypse. He died, according to the Roman martyrology, a martyr's death, under Diocletian, about 303. See Dupin, Nouvelle Bibl. des Auteurs Ecclis. (Paris, 1693), 1, 194.; Cave, Scriptorum Eccles. Hist. Lit.
