The African school of patristic writers, of which Tertullian is at once the earliest and the most imposing figure, and of which he was indeed to a large degree the direct founder, continued for a century after his death to include the main literary production of Latin Christianity. Thascius Caecilius Cyprianus, Bishop of Carthage from the year 248, though a pupil and an admirer of Tertullian, reverts in his own writings at once to orthodoxy and to an easy and copious diction. In earlier youth he had been a professor of rhetoric; after his conversion in mature life, he gave up all his wealth to the poor, and devoted his great literary gifts to apologetic and hortatory writings. He escaped the Decian persecution by retiring from Carthage; but a few years later he was executed in the renewed outbreak of judicial massacres which sullied the short and disastrous reign of Valerian. Forty years after Cyprian's death the rhetorician Arnobius of Sicca in Numidia renewed the attack on paganism, rather than the defence or exposition of Christianity, in the seven books _Adversus Nationes_, which he is said to have written as a proof of the sincerity of his conversion. "Uneven and ill-proportioned," in the phrase of Jerome, this work follows neither the elaborate rhetoric of the early African school, nor the chaster and more polished style of Cyprian, but rather renews the inferior and slovenly manner of the earlier antiquarians and encyclopedists. A free use of the rhetorical figures goes side by side with a general want of finish and occasional lapses into solecism. His literary gift is so small, and his knowledge of the religion he professes to defend so slight and so excessively inaccurate, that theologians and men of letters for once agree that his main value consists in the fragments of antiquarian information which he preserves. But he has a further claim to notice as the master of a celebrated pupil.
