virtue. Both the emperors were engaged in far distant wars, Valerian in the East, and Gallienus on the Rhine. All the hopes and resources the of the Romans were in themselves. In this emergency, senators resumed the defence of the republic, drew out the Prætorian guards, who had been left to garrison the capital, and filled up their numbers by enlisting into the public service the stoutest and most willing of the plebeians. The Alemanni, astonished with the sudden appearance of an army more numerous than their own, retired into Germany, laden with spoil; and their retreat was esteemed as a victory by the unwarlike Romans. Ref. 102
When Gallienus received the intelligence that his capital was delivered from the barbarians, he was much less delighted than alarmed with the courage of the senate, since it might one day prompt them to rescue the republic Ref. 103 from domestic tyranny, as well as from foreign invasion. His timid ingratitude was published to his subjects in an edict which prohibited the senators from exercising any military employment, and even from approaching the camps of the legions. But his fears were groundless. The rich and luxurious nobles, sinking into their natural character, accepted as a favour this disgraceful exemption from military service; and, as long as they were indulged in the enjoyment of their baths, their theatres, and their villas, they cheerfully resigned the more dangerous cares of empire to the rough hands of peasants and soldiers. Ref. 104
Another invasion of the Alemanni, of a more formidable aspect, but more glorious event, is mentioned by a writer of the Lower Empire. Three hundred thousand of that warlike people are said to have been vanquished, in a battle near Milan, by Gallienus in person, at the head of only ten thousand Romans. Ref. 105 We may however, with great probability, ascribe this incredible victory either to the credulity of the historian, or to some exaggerated exploits of one of the emperor’s lieutenants. It was by arms of a very different nature that Gallienus endeavoured to protect Italy from the fury of the Germans. He espoused Pipa, the daughter of a king of the Marcomanni, a Suevic tribe, which was often confounded with the Alemanni in their wars and conquests. Ref. 106 To the father, as the price of his alliance, he granted an ample settlement in Pannonia. The native charms of unpolished beauty seem to have fixed the daughter in the affections of the inconstant emperor, and the bands of policy were more firmly connected by those of love. But the haughty prejudice of Rome still refused the name of marriage to the profane mixture of a citizen and a barbarian; and has stigmatised the German princess with the opprobrious title of concubine of Gallienus. Ref. 107
III. We have already traced the emigration of the Goths from Scandinavia, or at least from Prussia, to the mouth of the Borysthenes, and have followed their victorious arms from the Borysthenes to the Danube. Under the reigns of Valerian and Gallienus the frontier of the last-mentioned river was perpetually infested by the inroads of Germans and Sarmatians; but it was defended by the Romans with more than usual firmness and success. The provinces that were the seat of war recruited the armies of Rome with an inexhaustible supply of hardy soldiers; and more than one of these Illyrian peasants attained the station, and displayed the abilities, of a general. Though flying parties of the barbarians, who incessantly hovered on the banks of the Danube, penetrated sometimes to the confines of Italy and Macedonia, their progress was commonly checked, or their return intercepted, by the Imperial lieutenants. Ref. 108 But the great stream of the Gothic hostilities was diverted into a very different channel. The Goths, in their new settlement of the Ukraine, soon became masters of the northern coast of the Euxine: to the south of that inland sea were situated the soft and wealthy provinces of Asia Minor, which possessed all that could attract, and nothing that could resist, a barbarian conqueror.
The banks of the Borysthenes are only sixty miles distant from the narrow entrance Ref. 109 of the peninsula of Crim Tartary, known to the ancients under the name of Chersonesus Taurica. Ref. 110 On that inhospitable shore, Euripides, embellishing with exquisite art the tales of antiquity, has placed the scene of one of his most affecting tragedies. Ref. 111 The bloody sacrifices of Diana, the arrival of Orestes and Pylades, and the triumph of virtue and religion over savage fierceness, serve to represent an historical truth, that the Tauri, the original inhabitants of the peninsula, were in some degree reclaimed from their brutal manners by a gradual intercourse with the Grecian colonies which settled along the maritime coast. The little kingdom of Bosphorus, whose capital was situated on the straits through which the Mæotis communicates itself to the Euxine, was composed of degenerate Greeks and half-civilised barbarians. It subsisted as an independent state from the time of the Peloponnesian war, Ref. 112 was at last swallowed up by the ambition of Mithridates, Ref. 113 and, with the rest of his dominions, sunk under the weight of the Roman arms. From the reign of Augustus, Ref. 114 the kings of Bosphorus were the humble, but not useless, allies of the empire. By presents, by arms, and by a slight fortification drawn across the isthmus, they effectually guarded against the roving plunderers of Sarmatia the access of a country which, from its peculiar situation and convenient harbours, commanded the Euxine Sea and Asia Minor. Ref. 115 As long as the sceptre was possessed by a lineal succession of kings, they acquitted themselves of their important charge with vigilance and success. Domestic factions, and the fears or private interest of obscure usurpers who seized on the vacant throne, admitted the Goths into the heart of Bosphorus. With the acquisition of a superfluous waste of fertile soil, the conquerors obtained the command of a naval force sufficient to transport their armies to the coast of Asia. Ref. 116 The ships used in the navigation of the Euxine were of a very singular construction. They were slight flat-bottomed barks framed of timber only, without the least mixture of iron, and occasionally covered with a shelving roof on the appearance of a tempest. Ref. 117 In these floating houses the Goths carelessly trusted themselves to the mercy of an unknown sea, under the conduct of sailors pressed into the service, and whose skill and fidelity were equally suspicious. But the hopes of plunder had banished every idea of danger, and a natural fearlessness of temper supplied in their minds the more rational confidence which is the just result of knowledge and experience. Warriors of such a daring spirit must have often murmured against the cowardice of their guides, who required the strongest assurances of a settled calm before they would venture to embark, and would scarcely ever be tempted to lose sight of the land. Such, at least, is the practice of the modern Turks; Ref. 118 and they are probably not inferior in the art of navigation to the ancient inhabitants of Bosphorus.
The fleet of the Goths, leaving the coast of Circassia on the left hand, first appeared before Pityus, Ref. 119 the utmost limits of the Roman provinces; a city provided with a convenient port, and fortified with a strong wall. Here they met with a resistance more obstinate than they had reason to expect from the feeble garrison of a distant fortress. They were repulsed; and their disappointment seemed to diminish the terror of the Gothic name. As long as Successianus, an officer of superior rank and merit, defended that frontier, all their efforts were ineffectual: but, as soon as he was removed by Valerian to a more honourable but less important station, they resumed the attack of Pityus; and, by the destruction of that city, obliterated the memory of their former disgrace. Ref. 120
Circling round the eastern extremity of the Euxine Sea, the navigation from Pityus to Trebizond is about three hundred miles. Ref. 121 The course of the Goths carried them in sight of the country of Colchis, so famous by the expedition of the Argonauts; and they even attempted, though without success, to pillage a rich temple at the mouth of the river Phasis. Trebizond, celebrated in the retreat of the Ten Thousand as an ancient colony of Greeks, Ref. 122 derived its wealth and splendour from the munificence of the emperor Hadrian, who had constructed an artificial port on a coast left destitute by nature of secure harbours. Ref. 123 The city was large and populous; a double enclosure of walls seemed to defy the fury of the Goths, and the usual garrison had been strengthened by a reinforcement of ten thousand men. But there are not any advantages capable of supplying the absence of discipline and vigilance. The numerous garrison of Trebizond, dissolved in riot and luxury, disdained to guard their impregnable fortifications. The Goths soon discovered the supine negligence of the besieged, erected a lofty pile of fascines, ascended the walls in the silence of the night, and entered the defenceless city, sword in hand. A general massacre of the people ensued, whilst the affrighted soldiers
