Nor can the number of thirty be completed, unless we include in the account the women and children who were honored with the Imperial title. The reign of Gallienus, distracted as it was, produced only nineteen pretenders to the throne: Cyriades, Macrianus, Balista, Odenathus, and Zenobia, in the East; in Gaul, and the western provinces, Posthumus, Lollianus, Victorinus, and his mother Victoria, Marius, and Tetricus; in Illyricum and the confines of the Danube, Ingenuus, Regillianus, and Aureolus; in Pontus, Saturninus; in Isauria, Trebellianus; Piso in Thessaly; Valens in Achaia; Æmilianus in Egypt; and Celsus in Africa. * To illustrate the obscure monuments of the life and death of each individual, would prove a laborious task, alike barren of instruction and of amusement. We may content ourselves with investigating some general characters, that most strongly mark the condition of the times, and the manners of the men, their pretensions, their motives, their fate, and their destructive consequences of their usurpation.

It is sufficiently known, that the odious appellation of Tyrant was often employed by the ancients to express the illegal seizure of supreme power, without any reference to the abuse of it. Several of the pretenders, who raised the standard of rebellion against the emperor Gallienus, were shining models of virtue, and almost all possessed a considerable share of vigor and ability. Their merit had recommended them to the favor of Valerian, and gradually promoted them to the most important commands of the empire. The generals, who assumed the title of Augustus, were either respected by their troops for their able conduct and severe discipline, or admired for valor and success in war, or beloved for frankness and generosity. The field of victory was often the scene of their election; and even the armorer Marius, the most contemptible of all the candidates for the purple, was distinguished, however by intrepid courage, matchless strength, and blunt honesty. His mean and recent trade cast, indeed, an air of ridicule on his elevation; * but his birth could not be more obscure than was that of the greater part of his rivals, who were born of peasants, and enlisted in the army as private soldiers. In times of confusion, every active genius finds the place assigned him by nature: in a general state of war, military merit is the road to glory and to greatness. Of the nineteen tyrants Tetricus only was a senator; Piso alone was a noble. The blood of Numa, through twenty-eight successive generations, ran in the veins of Calphurnius Piso, who, by female alliances, claimed a right of exhibiting, in his house, the images of Crassus and of the great Pompey. His ancestors had been repeatedly dignified with all the honors which the commonwealth could bestow; and of all the ancient families of Rome, the Calphurnian alone had survived the tyranny of the Cæsars. The personal qualities of Piso added new lustre to his race. The usurper Valens, by whose order he was killed, confessed, with deep remorse, that even an enemy ought to have respected the sanctity of Piso; and although he died in arms against Gallienus, the senate, with the emperor's generous permission, decreed the triumphal ornaments to the memory of so virtuous a rebel.

The lieutenants of Valerian were grateful to the father, whom they esteemed. They disdained to serve the luxurious indolence of his unworthy son. The throne of the Roman world was unsupported by any principle of loyalty; and treason against such a prince might easily be considered as patriotism to the state. Yet if we examine with candor the conduct of these usurpers, it will appear, that they were much oftener driven into rebellion by their fears, than urged to it by their ambition. They dreaded the cruel suspicions of Gallienus; they equally dreaded the capricious violence of their troops. If the dangerous favor of the army had imprudently declared them deserving of the purple, they were marked for sure destruction; and even prudence would counsel them to secure a short enjoyment of empire, and rather to try the fortune of war than to expect the hand of an executioner. When the clamor of the soldiers invested the reluctant victims with the ensigns of sovereign authority, they sometimes mourned in secret their approaching fate. "You have lost," said Saturninus, on the day of his elevation, "you have lost a useful commander, and you have made a very wretched emperor."

The apprehensions of Saturninus were justified by the repeated experience of revolutions. Of the nineteen tyrants who started up under the reign of Gallienus, there was not one who enjoyed a life of peace, or a natural death. As soon as they were invested with the bloody purple, they inspired their adherents with the same fears and ambition which had occasioned their own revolt. Encompassed with domestic conspiracy, military sedition, and civil war, they trembled on the edge of precipices, in which, after a
