Circling round the eastern extremity of the Euxine Sea, the navigation from Pityus to Trebizond is about three hundred miles. 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, derived its wealth and splendor from the magnificence of the emperor Hadrian, who had constructed an artificial port on a coast left destitute by nature of secure harbors. 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 reenforcement 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 escaped through the opposite gates of the town. The most holy temples, and the most splendid edifices, were involved in a common destruction. The booty that fell into the hands of the Goths was immense: the wealth of the adjacent countries had been deposited in Trebizond, as in a secure place of refuge. The number of captives was incredible, as the victorious barbarians ranged without opposition through the extensive province of Pontus. The rich spoils of Trebizond filled a great fleet of ships that had been found in the port. The robust youth of the sea-coast were chained to the oar; and the Goths, satisfied with the success of their first naval expedition, returned in triumph to their new establishment in the kingdom of Bosphorus.

The second expedition of the Goths was undertaken with greater powers of men and ships; but they steered a different course, and, disdaining the exhausted provinces of Pontus, followed the western coast of the Euxine, passed before the wide mouths of the Borysthenes, the Niester, and the Danube, and increasing their fleet by the capture of a great number of fishing barks, they approached the narrow outlet through which the Euxine Sea pours its waters into the Mediterranean, and divides the continents of Europe and Asia. The garrison of Chalcedon was encamped near the temple of Jupiter Urius, on a promontory that commanded the entrance of the Strait; and so inconsiderable were the dreaded invasions of the barbarians that this body of troops surpassed in number the Gothic army. But it was in numbers alone that they surpassed it. They deserted with precipitation their advantageous post, and abandoned the town of Chalcedon, most plentifully stored with arms and money, to the discretion of the conquerors. Whilst they hesitated whether they should prefer the sea or land Europe or Asia, for the scene of their hostilities, a perfidious fugitive pointed out Nicomedia, * once the capital of the kings of Bithynia, as a rich and easy conquest. He guided the march which was only sixty miles from the camp of Chalcedon, directed the resistless attack, and partook of the booty; for the Goths had learned sufficient policy to reward the traitor whom they detested. Nice, Prusa, Apamæa, Cius, cities that had sometimes rivalled, or imitated, the splendor of Nicomedia, were involved in the same calamity, which, in a few weeks, raged without control through the whole province of Bithynia. Three hundred years of peace, enjoyed by the soft inhabitants of Asia, had abolished the exercise of arms, and removed the apprehension of danger. The ancient walls were suffered to moulder away, and all the revenue of the most opulent cities was reserved for the construction of baths, temples, and theatres.

When the city of Cyzicus withstood the utmost effort of Mithridates, it was distinguished by wise laws, a naval power of two hundred galleys, and three arsenals, of arms, of military engines, and of corn. It was still the seat of wealth and luxury; but of its ancient strength, nothing remained except the situation, in a little island of the Propontis, connected with the continent of Asia only by two bridges. From the recent sack of Prusa, the Goths advanced within eighteen miles. of the city, which they had devoted to destruction; but the ruin of Cyzicus was delayed by a fortunate accident. The season was rainy, and the Lake Apolloniates, the reservoir of all the springs of Mount Olympus, rose to an uncommon height. The little river of Rhyndacus, which issues from the lake, swelled into a broad and rapid stream, and stopped the progress of the Goths. Their retreat to the maritime city of Heraclea, where the fleet had probably been stationed, was attended by a long train of wagons, laden with the spoils of Bithynia, and was marked by the flames of Nice and Nicomedia, which they wantonly burnt. Some obscure hints are mentioned of a doubtful combat that secured their retreat. But even a complete victory would have been
