murdering the new emperor, and Valerian was elected in his stead. This prince was already an old man at the time of his election; but he lived long enough to look back upon the day of his inauguration as the blackest in his life. Memorable were the calamities which fell upon himself, and upon the empire, during his reign. He began by associating to himself his son Gallienus; partly, perhaps, for his own relief, partly to indulge the senate in their steady plan of dividing the imperial authority. The two emperors undertook the military defence of the empire, Gallienus proceeding to the German frontier, Valerian to the eastern. Under Gallienus, the Franks began first to make themselves heard of. Breaking into Gaul they passed through that country and Spain; captured Tarragona in their route; crossed over to Africa, and conquered Mauritania. At the same time, the Alemanni, who had been in motion since the time of Caracalla, broke into Lombardy, across the Rhætian Alps. The senate, left without aid from either emperor, were obliged to make preparations for the common defence against this host of barbarians. Luckily, the very magnitude of the enemy's success, by overloading him with booty, made it his interest to retire without fighting; and the degraded senate, hanging upon the traces of their retiring footsteps, without fighting, or daring to fight, claimed the honors of a victory. Even then, however, they did more than was agreeable to the jealousies of Gallienus, who, by an edict, publicly rebuked their presumption, and forbade them in future to appear amongst the legions, or to exercise any military functions. He himself, meanwhile, could devise no better way of providing for the public security, than by marrying the daughter of his chief enemy, the king of the Marcomanni. On this side of Europe, the barbarians were thus quieted for the present; but the Goths of the Ukraine, in three marauding expeditions of unprecedented violence, ravaged the wealthy regions of Asia Minor, as well as the islands of the Archipelago; and at length, under the guidance of deserters, landed in the port of the Pyræus. Advancing from this point, after sacking Athens and the chief cities of Greece, they marched upon Epirus, and began to threaten Italy. But the defection at this crisis of a conspicuous chieftain, and the burden of their booty, made these wild marauders anxious to provide for a safe retreat; the imperial commanders in Moesia listened eagerly to their offers: and it set the seal to the dishonors of the state, that, after having traversed so vast a range of territory almost without resistance, these blood-stained brigands were now suffered to retire under the very guardianship of those whom they had just visited with military execution.
