The generous mind of Count Boniface was tortured by the exquisite distress of beholding the ruin which he had occasioned, and whose rapid progress he was unable to check. After the loss of a battle he retired into Hippo Regius; where he was immediately besieged by an enemy, who considered him as the real bulwark of Africa. The maritime colony of Hippo, about two hundred miles westward of Carthage, had formerly acquired the distinguishing epithet of Regius, from the residence of Numidian kings; and some remains of trade and populousness still adhere to the modern city, which is known in Europe by the corrupted name of Bona. The military labors, and anxious reflections, of Count Boniface, were alleviated by the edifying conversation of his friend St. Augustin; till that bishop, the light and pillar of the Catholic church, was gently released, in the third month of the siege, and in the seventy-sixth year of his age, from the actual and the impending calamities of his country. The youth of Augustin had been stained by the vices and errors which he so ingenuously confesses; but from the moment of his conversion to that of his death, the manners of the bishop of Hippo were pure and austere: and the most conspicuous of his virtues was an ardent zeal against heretics of every denomination; the Manichæans, the Donatists, and the Pelagians, against whom he waged a perpetual controversy. When the city, some months after his death, was burnt by the Vandals, the library was fortunately saved, which contained his voluminous writings; two hundred and thirty-two separate books or treatises on theological subjects, besides a complete exposition of the psalter and the gospel, and a copious magazine of epistles and homilies. According to the judgment of the most impartial critics, the superficial learning of Augustin was confined to the Latin language; and his style, though sometimes animated by the eloquence of passion, is usually clouded by false and affected rhetoric. But he possessed a strong, capacious, argumentative mind; he boldly sounded the dark abyss of grace, predestination, free will, and original sin; and the rigid system of Christianity which he framed or restored, has been entertained, with public applause, and secret reluctance, by the Latin church.
