Augustine is the person from the ancient world about whom we know most. He is the author of an intimate masterpiece, the Confessions, which continues to delight and challenge its many admirers. In it he writes about his infancy and his schooling in the classics in late Roman North Africa, his remarkable mother, his sexual sins ('Give me chastity, but not yet', he famously prayed), his time in an outlawed heretical sect, his worldly career and friendships and his gradual return to God. His account of his own eventual conversion is a classic study of anguish, hesitation and what he believes to be God's intervention. It has inspired philosophers, Christian thinkers and monastic followers, but it still leaves readers wondering why exactly Augustine chose to compose a work like none before it. Robin Lane Fox follows Augustine on a brilliantly-described journey, combining the latest scholarship with recently-found letters and sermons by Augustine himself to give a portrait of his subject which is subtly different from older biographies. Augustine's heretical years as a Manichaean, his relation to non-Christian philosophy, his mystical aspirations and the nature of his conversion are among the aspects of his life which stand out in a sharper light. For the first time Lane Fox compares him with two contemporaries, an older pagan and a younger Christian, each of whom also wrote about themselves, and who illumine Augustine's life and writings by their different choices. More than a decade passed between Augustine's conversion and his beginning the Confessions. Lane Fox argues that the Confessions and their thinking were the results of a long gestation over these years, not a sudden change of perspective, but that they were then written as a single swift composition and that its final books are a coherent consummation of its scriptural meditation and personal biography.
