The revolutions of the palace, which left the Western Empire without a defender, and without a lawful prince, dispelled the apprehensions and stimulated the avarice of Genseric. He immediately equipped a numerous fleet of Vandals and Moors, and cast anchor at the mouth of the Tiber, about three months after the death of Valentinian and the elevation of Maximus to the imperial throne.
The private life of the senator Petronius Maximus was often alleged as a rare example of human felicity. His birth was noble and illustrious, since he descended from the Anician family, his dignity was supported by an adequate patrimony in land and money; and these advantages of fortune were accompanied with liberal arts and decent manners, which adorn or imitate the inestimable gifts of genius and virtue. The luxury of his palace and table was hospitable and elegant. Whenever Maximus appeared in public, he was surrounded by a train of grateful and obsequious clients; and it is possible that, among these clients, he might deserve and possess some real friends. His merit was rewarded by the favour of the prince and senate; he thrice exercised the office of prætorian prefect of Italy; he was twice invested with the consulship, and he obtained the rank of patrician.
These civil honours were not incompatible with the enjoyment of leisure and tranquillity; his hours, according to the demands of pleasure or reason, were accurately distributed by a water-clock; and this avarice of time may be allowed to prove the sense which Maximus entertained of his own happiness. The injury which he received from the emperor Valentinian appears to excuse the most bloody revenge. Yet a philosopher might have reflected that, if the resistance of his wife had been sincere, her chastity was still inviolate, and that it could never be restored if she had consented to the will of the adulterer. A patriot would have hesitated, before plunging himself and his country into those inevitable calamities which must follow the extinction of the royal house of Theodosius. The imprudent Maximus disregarded these salutary considerations; he gratified his resentment and ambition, he saw the bleeding corpse of Valentinian at his feet, and heard himself saluted emperor by the unanimous voice of the senate and people. But the day of his inauguration was the last day of his happiness. He was imprisoned (such is the lively expression of Sidonius) in the palace; and, after passing a sleepless night, he sighed that he had attained the summit of his wishes, and aspired only to descend from the dangerous elevation. Oppressed by the weight of the diadem, he communicated his anxious thoughts to his friend and quæstor Fulgentius; and when he looked back with unavailing regret on the secure pleasures of his former life, the emperor exclaimed, “O fortunate Damocles, thy reign began and ended with the same dinner!” a well-known allusion, which Fulgentius afterwards repeated as an instructive lesson for princes and subjects.
[455-456 A.D.]
The reign of Maximus continued about three months. His hours, of which he had lost the command, were disturbed by remorse, or guilt, or terror; and his throne was shaken by the seditions of the soldiers, the people, and the confederate barbarians. The marriage of his son Palladius with the eldest daughter of the late emperor might tend to establish the hereditary succession of his family; but the violence which he offered to the empress Eudoxia could proceed only from the blind impulse of lust or revenge. His own wife, the cause of these tragic events, had been seasonably removed by death; and the widow of Valentinian was compelled to violate her decent mourning, perhaps her real grief, and to submit to the embraces of a presumptuous usurper, whom she suspected as the assassin of her deceased husband.
These suspicions were soon justified by the indiscreet confession of Maximus himself; and he wantonly provoked the hatred of his reluctant bride, who was still conscious that she was descended from a line of emperors. From the East, however, Eudoxia could not hope to obtain any effectual assistance; her father and her aunt Pulcheria were dead; her mother languished at Jerusalem in disgrace and exile; and the sceptre of Constantinople was in the hands of a stranger. She directed her eyes towards Carthage, secretly implored the aid of the king of the Vandals; and persuaded Genseric to improve the fair opportunity of disguising his rapacious designs by the specious names of honour, justice, and compassion. Whatever abilities Maximus might have shown in a subordinate station, he was found incapable of administering an empire; and though he might easily have been informed of the naval preparations which were made on the opposite shores of Africa, he expected with supine indifference the approach of the enemy, without adopting any measures of defence, of negotiation, or of a timely retreat.
