16 centuries ago, the greatest empire the world had ever seen, The Roman Empire, symbolically, with the sack of its capitol, the eternal city of Rome, died. It was the end of 1,000 years of civilization by the hands of barbarian hordes from Germania. Many Romans argued at the time that the Empire was crumbling because the ancient gods had been displaced by the now official-and dominant-Christian faith. The City of God is a rebuttal of this belief-but that is far from all that it is. Second only to St. Augustine's Confessions in popularity, The City of God is the greatest and most comprehensive of St. Augustine's works.
