Valentinian, when he received the title of Augustus, was no more than six years of age; and his long minority was intrusted to the guardian care of a mother, who might assert a female claim to the succession of the Western empire. Placidia envied, but she could not equal, the reputation and virtues of the wife and sister of Theodosius, the elegant genius of Eudocia, the wise and successful policy of Pulcheria. The mother of Valentinian was jealous of the power which she was incapable of exercising; she reigned twenty-five years, in the name of her son; and the character of that unworthy emperor gradually countenanced the suspicion that Placidia had enervated his youth by a dissolute education, and studiously diverted his attention from every manly and honorable pursuit. Amidst the decay of military spirit, her armies were commanded by two generals, Ætius and Boniface, who may be deservedly named as the last of the Romans. Their union might have supported a sinking empire; their discord was the fatal and immediate cause of the loss of Africa. The invasion and defeat of Attila have immortalized the fame of Ætius; and though time has thrown a shade over the exploits of his rival, the defence of Marseilles, and the deliverance of Africa, attest the military talents of Count Boniface. In the field of battle, in partial encounters, in single combats, he was still the terror of the Barbarians: the clergy, and particularly his friend Augustin, were edified by the Christian piety which had once tempted him to retire from the world; the people applauded his spotless integrity; the army dreaded his equal and inexorable justice, which may be displayed in a very singular example. A peasant, who complained of the criminal intimacy between his wife and a Gothic soldier, was directed to attend his tribunal the following day: in the evening the count, who had diligently informed himself of the time and place of the assignation, mounted his horse, rode ten miles into the country, surprised the guilty couple, punished the soldier with instant death, and silenced the complaints of the husband by presenting him, the next morning, with the head of the adulterer. The abilities of Ætius and Boniface might have been usefully employed against the public enemies, in separate and important commands; but the experience of their past conduct should have decided the real favor and confidence of the empress Placidia. In the melancholy season of her exile and distress, Boniface alone had maintained her cause with unshaken fidelity: and the troops and treasures of Africa had essentially contributed to extinguish the rebellion. The same rebellion had been supported by the zeal and activity of Ætius, who brought an army of sixty thousand Huns from the Danube to the confines of Italy, for the service of the usurper. The untimely death of John compelled him to accept an advantageous treaty; but he still continued, the subject
