When Augustine was about 16, his parents sent him to the university at Carthage, the largest city in the region. There he studied literature and poetry, in preparation for a career as a rhetor, a professional public speaker and teacher of rhetoric. Soon after Augustine came to Carthage, his father died, leaving Augustine as the nominal head of the family. In Carthage, he set up a household with a concubine, the mother of his son, Adeodatus, born about 372. During this period, he read the book that began his spiritual journey: Cicero's Hortensius, which he says inspired him with the desire to seek the truth, in whatever form he might find it. In Carthage, Augustine also encountered Manichaeism, the religion that dominated his life for the following decade. Augustine was attracted to Manichaeism's clear dividing line between good and evil, its highly intellectual mythology, and its strict moral standards.
After Augustine finished his studies, he briefly returned to Thagaste to teach, but soon went back to Carthage, where opportunities were more plentiful. Augustine became a successful public speaker and teacher. Encouraged by wealthy Manichee friends, he moved on to Rome in 383, hoping to advance his career. Rome proved to be disappointing, but Augustine's talents caught the eye of a Roman official who recommended Augustine for the position of public orator for the imperial city of Milan.
In 384, Augustine moved to Milan, where he heard the preaching of Bishop Ambrose. Augustine had always considered Christianity intellectually lacking, but Ambrose's application of Neo-Platonic ideas to the interpretation of Christian scripture, presented with Ambrose's famous eloquence, captured Augustine's interest. Augustine had been growing steadily dissatisfied with Manichaeism, and Ambrose's influence encouraged him to make a break with the Manichees. Augustine read the works of the Neo-Platonists himself, and this reading revolutionized his understanding of Christianity. Meanwhile, Augustine's career was flourishing, and his worldly prospects were bright. His mother had followed him to Milan, and she arranged an advantageous marriage to a Christian girl from a good family, requiring Augustine to send his concubine away. In the fall of 386, he had a conversion experience that convinced him to renounce his career and his marriage prospects in order to dedicate his life to God. He spent the winter with a group of like-minded friends, withdrawn from the world, reading and discussing Christianity. At Easter 387, he was finally baptized by Bishop Ambrose. On their way back to Africa, his group of friends and family was delayed at the coastal city of Ostia, where Monica fell ill and died. The account of Augustine's life as set out in the Confessions ends there, when Augustine was about 35 years old, but his life's work was only beginning.
