The empress Justina did not long survive her return to Italy; and, though she beheld the triumph of Theodosius, she was not allowed to influence the government of her son. Ref. 108 The pernicious attachment to the Arian sect, which Valentinian had imbibed from her example and instructions, was soon erased by the lessons of a more orthodox education. His growing zeal for the faith of Nice and his filial reverence for the character and authority of Ambrose disposed the Catholics to entertain the most favourable opinion of the virtues of the young emperor of the West. Ref. 109 They applauded his chastity and temperance, his contempt of pleasure, his application to business, and his tender affection for his two sisters; which could not, however, seduce his impartial equity to pronounce an unjust sentence against the meanest of his subjects. But this amiable youth, before he had accomplished the twentieth year of his age, was oppressed by domestic treason; and the empire was again involved in the horrors of a civil war. Arbogastes, Ref. 110 a gallant soldier of the nation of the Franks, held the second rank in the service of Gratian. On the death of his master, he joined the standard of Theodosius; contributed, by his valour and military conduct, to the destruction of the tyrant; and was appointed, after the victory, master-general of the armies of Gaul. His real merit and apparent fidelity had gained the confidence both of the prince and people; his boundless liberality corrupted the allegiance of the troops; and, whilst he was universally esteemed as the pillar of the state, the bold and crafty Barbarian was secretly determined either to rule or to ruin the empire of the West. The important commands of the army were distributed among the Franks; the creatures of Arbogastes were promoted to all the honours and offices of the civil government; the progress of the conspiracy removed every faithful servant from the presence of Valentinian; and the emperor, without power and without intelligence, insensibly sunk into the precarious and dependent condition of a captive. Ref. 111 The indignation which he expressed, though it might arise only from the rash and impatient temper of youth, may be candidly ascribed to the generous spirit of a prince who felt that he was not unworthy to reign. He secretly invited the archbishop of Milan to undertake the office of a mediator, as the pledge of his sincerity and the guardian of his safety. He contrived to apprise the emperor of the East of his helpless situation; and he declared that, unless Theodosius could speedily march to his assistance, he must attempt to escape from the palace, or rather prison, of Vienna in Gaul, where he had imprudently fixed his residence in the midst of the hostile faction. But the hopes of relief were distant and doubtful; and, as every day furnished some new provocation, the emperor, without strength or counsel, too hastily resolved to risk an immediate contest with his powerful general. He received Arbogastes on the throne; and, as the count approached with some appearance of respect, delivered to him a paper, which dismissed him from all his employments. “My authority,” replied Arbogastes with insulting coolness, “does not depend on the smile, or the frown, of a monarch;” and he contemptuously threw the paper on the ground. Ref. 112 The indignant monarch snatched at the sword of one of the guards, which he struggled to draw from its scabbard; and it was not without some degree of violence that he was prevented from using the deadly weapon against his enemy, or against himself. A few days after this extraordinary quarrel, in which he had exposed his resentment and his weakness, the unfortunate Valentinian was found strangled in his apartment; and some pains were employed to disguise the manifest guilt of Arbogastes, and to persuade the world that the death of the young emperor had been the voluntary effect of his own despair. Ref. 113 His body was conducted with decent pomp to the sepulchre of Milan; and the archbishop pronounced a funeral oration, to commemorate his virtue and his misfortunes. Ref. 114 On this occasion, the humanity of Ambrose tempted him to make a singular breach in his theological system, and to comfort the weeping sisters of Valentinian, by the firm assurance that their pious brother, though he had not received the sacrament of baptism, was introduced, without difficulty, into the mansions of eternal bliss. Ref. 115
The prudence of Arbogastes had prepared the success of his ambitious designs; and the provincials, in whose breasts every sentiment of patriotism or loyalty was extinguished, expected, with tame resignation, the unknown master, whom the choice of a Frank might place on the Imperial throne. But some remains of pride and prejudice still opposed the elevation of Arbogastes himself; and the judicious Barbarian thought it more advisible to reign under the name of some dependent Roman. He bestowed the purple on the rhetorician Eugenius; Ref. 116 whom he had already raised from the place of his domestic secretary to the rank of master of the offices. Ref. 117 In the course both of his private and public service, the count had always approved the attachment and abilities of Eugenius; his learning and eloquence, supported by the gravity of his manners, recommended him to the esteem of the people; and the reluctance with which he seemed to ascend the throne may inspire a favourable prejudice of his virtue and moderation. The ambassadors of the new emperor were immediately despatched to the court of Theodosius, to communicate, with affected grief, the unfortunate accident of the death of Valentinian; and, without mentioning the name of Arbogastes, to request that the monarch of the East would embrace, as his lawful colleague, the respectable citizen who had obtained the unanimous suffrage of the armies and provinces of the West. Ref. 118 Theodosius was justly provoked that the perfidy of a Barbarian should have destroyed, in a moment, the labours and the fruit of his former victory; and he was excited by the tears of his beloved wife Ref. 119 to revenge the fate of her unhappy brother and once more to assert by arms the violated majesty of the throne. But, as the second conquest of the West was a task of difficulty and danger, he dismissed, with splendid presents and an ambiguous answer, the ambassadors of Eugenius; and almost two years were consumed in the preparations of the civil war. Before he formed any decisive resolution, the pious emperor was anxious to discover the will of Heaven; and, as the progress of Christianity had silenced the oracles of Delphi and Dodona, he consulted an Egyptian monk, who possessed, in the opinion of the age, the gift of miracles and the knowledge of futurity. Eutropius, one of the favourite eunuchs of the palace of Constantinople, embarked for Alexandria, from whence he sailed up the Nile as far as the city of Lycopolis, or of Wolves, in the remote province of Thebais. Ref. 120 In the neighbourhood of that city, and on the summit of a lofty mountain, the holy John Ref. 121 had constructed, with his own hands, an humble cell, in which he had dwelt above fifty years, without opening his door, without seeing the face of a woman, and without tasting any food that had been prepared by fire or any human art. Five days of the week he spent in prayer and meditation; but on Saturdays and Sundays he regularly opened a small window, and gave audience to the crowd of suppliants who successively flowed from every part of the Christian world. The eunuch of Theodosius approached the window with respectful steps, proposed his questions concerning the event of the civil war, and soon returned with a favourable oracle, which animated the courage of the emperor by the assurance of a bloody but infallible victory. Ref. 122 The accomplishment of the prediction was forwarded by all the means that human prudence could supply. The industry of the two master-generals, Stilicho and Timasius, was directed to recruit the numbers, and to revive the discipline, of the Roman legions. The formidable troops of Barbarians marched under the ensigns of their national chieftains. The Iberian, the Arab, and the Goth, who gazed on each other with mutual astonishment, were enlisted in the service of the same prince; and the renowned Alaric acquired, in the school of Theodosius, the knowledge of the art of war which he afterwards
