Baring-Gould’s sources: Roman Martyrology. Usuardus. Authority: — S. Jerome, De viris Very little is known of this saint, except that S. Jerome calls him one of the pillars of the Church. He studied oratory in Greece, being a Greek by birth, but abandoned all prospect of advancement in the world for the cause of Christ, and was made bishop of Pettau, in Upper Pannonia, or Styria. He wrote in Latin, but his style was not good, as Greek was his native tongue, and he never acquired complete facility in the use of Latin. He commented on Holy Scriptures, and combated several of the prevailing heresies. But all his works have been lost save a treatise on the Apocalypse, and another on the Creation of the World, which has been published by Cave.* The treatise on the Apocalypse is, however, either wrongly attributed to him, or has suffered alteration and interpolation; for S. Jerome says that Victorinus favoured Millennarian views, whereas the author of this tract combats these doctrines. His commentaries on Genesis, Exodus, Leviticus, Isaiah, Ezekiel, Habakkuk, Ecclesiastes, the Canticles, and on S. Matthew are lost. S. Jerome says that he was a martyr, probably in the persecution of 303.
