the frequent and sudden incursions of the tribes of Latium, the perpetual enemies of the republic. With the progress of Roman greatness, the city and its inhabitants gradually increased, filled up the vacant space, pierced through the useless walls, covered the field of Mars, and, on every side, followed the public highways in long and beautiful suburbs. The extent of the new walls, erected by Aurelian, and finished in the reign of Probus, was magnified by popular estimation to near fifty, but is reduced by accurate measurement to about twenty-one miles. It was a great but a melancholy labor, since the defence of the capital betrayed the decline of the monarchy. The Romans of a more prosperous age, who trusted to the arms of the legions the safety of the frontier camps, were very far from entertaining a suspicion, that it would ever become necessary to fortify the seat of empire against the inroads of the barbarians.

The victory of Claudius over the Goths, and the success of Aurelian against the Alemanni, had already restored to the arms of Rome their ancient superiority over the barbarous nations of the North. To chastise domestic tyrants, and to reunite the dismembered parts of the empire, was a task reserved for the second of those warlike emperors. Though he was acknowledged by the senate and people, the frontiers of Italy, Africa, Illyricum, and Thrace, confined the limits of his reign. Gaul, Spain, and Britain, Egypt, Syria, and Asia Minor, were still possessed by two rebels, who alone, out of so numerous a list, had hitherto escaped the dangers of their situation; and to complete the ignominy of Rome, these rival thrones had been usurped by women.

A rapid succession of monarchs had arisen and fallen in the provinces of Gaul. The rigid virtues of Posthumus served only to hasten his destruction. After suppressing a competitor, who had assumed the purple at Mentz, he refused to gratify his troops with the plunder of the rebellious city; and in the seventh year of his reign, became the victim of their disappointed avarice. The death of Victorinus, his friend and associate, was occasioned by a less worthy cause. The shining accomplishments of that prince were stained by a licentious passion, which he indulged in acts of violence, with too little regard to the laws of society, or even to those of love. He was slain at Cologne, by a conspiracy of jealous husbands, whose revenge would have appeared more justifiable, had they spared the innocence of his son. After the murder of so many valiant princes, it is somewhat remarkable, that a female for a long time controlled the fierce legions of Gaul, and still more singular, that she was the mother of the unfortunate Victorinus. The arts and treasures of Victoria enabled her successively to place Marius and Tetricus on the throne, and to reign with a manly vigor under the name of those dependent emperors. Money of copper, of silver, and of gold, was coined in her name; she assumed the titles of Augusta and Mother of the Camps: her power ended only with her life; but her life was perhaps shortened by the ingratitude of Tetricus.

When, at the instigation of his ambitious patroness, Tetricus assumed the ensigns of royalty, he was governor of the peaceful province of Aquitaine, an employment suited to his character and education. He reigned four or five years over Gaul, Spain, and Britain, the slave and sovereign of a licentious army, whom he dreaded, and by whom he was despised. The valor and fortune of Aurelian at length opened the prospect of a deliverance. He ventured to disclose his melancholy situation, and conjured the emperor to hasten to the relief of his unhappy rival. Had this secret correspondence reached the ears of the soldiers, it would most probably have cost Tetricus his life; nor could he resign the sceptre of the West without committing an act of treason against himself. He affected the appearances of a civil war, led his forces into the field, against Aurelian, posted them in the most disadvantageous manner, betrayed his own counsels to his enemy, and with a few chosen friends deserted in the beginning of the action. The rebel legions, though disordered and dismayed by the unexpected treachery of their chief, defended themselves with desperate valor, till they were cut in pieces almost to a man, in this bloody and memorable battle, which was fought near Chalons in Champagne. The retreat of the irregular auxiliaries, Franks and Batavians, whom the conqueror soon compelled or persuaded to repass the Rhine, restored the general tranquillity, and the power of Aurelian was acknowledged from the wall of Antoninus to the columns of Hercules.

As early as the reign of Claudius, the city of Autun, alone and unassisted, had ventured to declare against the legions of Gaul. After a siege of seven months, they stormed and plundered that unfortunate city, already wasted by famine. Lyons, on the contrary, had resisted with obstinate disaffection the arms of
