The Confessions of Augustine carry his life down to the age of thirtythree, from his birth at Tagaste in Numidia in A.D. 354 to A.D. 387, when he was converted to Christianity by Ambrose in Milan. He wrote the Confessions ten years later, in A.D. 397–8, at the age of forty-three or forty-four, when he had just been made Bishop of Hippo Regius, the modern Bône, in North Africa. The work is an autobiography, the one exstant autobiography in Latin literature: but it is peculiar in being addressed primarily to the Deity and in being a record not of the writer's own achievements intended for his own glory, but of all the way by which the power of God had led him. So while in places it does narrate the events of his life and the development of his mind and thought, at other places it breaks out into rapturous praise and adoration of his Redeemer and becomes not so much a narration as a prose hymn, sometimes in a minor key of contrite repentance for the sins and faults of youth now pardoned, sometimes in an exalted strain of ecstatic love, worship, and devotion towards the One to whose service he is now wholly surrendered. Under the eye of the Omniscient, Augustine reviews his life from childhood till his conversion: it is a stern and unflinching self-examination: the pranks of his boyhood are tested for early evidences of sin with the same relentless analysis as the vices, the ambitions, and self-will of his youth and manhood. We have his school-days at his native Tagaste and at the neighbouring town of Madaura: we have the turbulence of his adolescence at Carthage: we see him as a student of rhetoric at Carthage and as a professor of rhetoric at Carthage, Rome and Milan: we are told how the beginnings of his spiritual awareness were excited by the reading of Cicero's Hortensius: we learn of his long association with the quasi-Christian sect of the Manichaeans, of his growing dissatisfaction with their doctrine of a material and finite Deity, and of his long perplexity about religious problems—until through the preaching of Ambrose at Milan and through a study of Neo-platonism, he comes to a realization of an immaterial, non-temporal, non-spatial One.
