In Claudian's distinguished contemporary, the Spanish poet Aurelius Prudentius Clemens, Christian Latin poetry reached complete maturity. His collected poems were published at Rome in 404, the year celebrated by Claudian as that of the sixth consulship of Honorius. Before Prudentius, Christian poetry had been slight in amount and rude or tentative in manner. We have already had occasion to notice its earliest efforts in the rude verses of Commodianus. The revival of letters in the fourth century, so far as it went, affected Christian as well as secular poetry. Under Constantine, a Spanish deacon, one Gaius Vettius Aquilinus Juvencus, put the Gospel narrative into respectable hexameters, which are still extant. The poems and hymns which have come down under the name of Bishop Hilary of Poitiers are probably spurious, and a similar doubt attaches to those ascribed to the eminent grammarian and rhetorician, Gaius Marius Victorinus, after his conversion. Before Prudentius published his collection, the hymns of St. Ambrose had been written, and were in use among the Western Churches. But these, though they formed the type for all later hymn-writers, were few in number. Out of the so-called Ambrosian hymns a rigorous criticism only allows five or six as authentic. These, however, include two world-famed pieces, still in daily use by the Church, the _Aeterne rerum Conditor_ and the _Deus Creator omnium,_ and the equally famous _Veni Redemptor_. To the form thus established by St. Ambrose, Prudentius, in his two books of lyrical poems, gave a larger volume and a more sustained literary power. The _Cathemerina,_ a series of poems on the Christian life, and the _Peristephanon,_ a book of the praise of Christian martyrs--St. Lawrence, St. Vincent, St. Agnes, among other less celebrated names--at once represent the most substantial addition made to Latin lyrical poetry since Horace, and the complete triumph of the new religion. They are not, like the Ambrosian hymns, brief pieces meant for actual singing in churches. Out of the twenty-six poems only three are under one hundred lines in length, and that on the martyrdom of St. Romanus of Antioch runs to no less than eleven hundred and forty, almost the proportions of a small epic. But in the brilliance and vigour of their language, their picturesque style, and the new joy that, in spite of their asceticism, burns throughout them, they gave an impulse of immense force towards the development of Christian literature. In merely technical quality they are superior to any poetry of the time, Claudian alone excepted; in their fullness of life, in the exultant tone which kindles and sustains them, they make Claudian grow pale like a candle-flame at dawn.
