The History of the Decline and Fall of the Roman Empire. Эдвард Гиббон

of Anchialus in Thrace were rendered as safe as they were salutary; but the rich pastures of Thessalonica were foraged by the Scythian cavalry; the delicious vale of Tempe, three hundred miles from the Danube, was continually alarmed by the sound of war; ^{Ref. 119} and no unfortified spot, however distant or solitary, could securely enjoy the blessings of peace. The straits of Thermopylæ, which seemed to protect, but which had so often betrayed, the safety of Greece, were diligently strengthened by the labours of Justinian. From the edge of the seashore, through the forests and valleys, and as far as the summit of the Thessalian mountains, a strong wall was continued, which occupied every practicable entrance. Instead of an hasty crowd of peasants, a garrison of two thousand soldiers was stationed along the rampart; granaries of corn and reservoirs of water were provided for their use; and, by a precaution that inspired the cowardice which it foresaw, convenient fortresses were erected for their retreat. The walls of Corinth, overthrown by an earthquake, and the mouldering bulwarks of Athens and Platæa, were carefully restored; the Barbarians were discouraged by the prospect of successive and painful sieges; and the naked cities of Peloponnesus were covered by the fortifications of the isthmus of Corinth. At the extremity of Europe, another peninsula, the Thracian Chersonesus, runs three days’ journey into the sea, to form, with the adjacent shores of Asia, the straits of the Hellespont. The intervals between eleven populous towns were filled by lofty woods, fair pastures, and arable lands; and the isthmus, of thirty-seven stadia or furlongs, had been fortified by a Spartan general nine hundred years before the reign of Justinian. ^{Ref. 120} In an age of freedom and valour, the slightest rampart may prevent a surprise; and Procopius appears insensible of the superiority of ancient times, while he praises the solid construction and double parapet of a wall whose long arms stretched on either side into the sea; but whose strength was deemed insufficient to guard the Chersonesus, if each city, and particularly Gallipoli and Sestus, had not been secured by their peculiar fortifications. The long wall, as it was emphatically styled, was a work as disgraceful in the object, as it was respectable in the execution. The riches of a capital diffuse themselves over the neighbouring country, and the territory of Constantinople, a paradise of nature, was adorned with the luxurious gardens and villas of the senators and opulent citizens. But their wealth served only to attract the bold and rapacious Barbarians; the noblest of the Romans, in the bosom of peaceful indolence, were led away into Scythian captivity, and their sovereign might view from his palace the hostile flames which were insolently spread to the gates of the Imperial city. At the distance only of forty miles Anastasius was constrained to establish a last frontier; his long wall, of sixty miles from the Propontis to the Euxine, proclaimed the impotence of his arms; and, as the danger became more imminent, new fortifications were added by the indefatigable prudence of Justinian. ^{Ref. 121}

      Asia Minor, after the submission of the Isaurians, ^{Ref. 122} remained without enemies and without fortifications. Those bold savages, who had disdained to be the subjects of Gallienus, persisted two hundred and thirty years in a life of independence and rapine. The most successful princes respected the strength of the mountains and the despair of the natives; their fierce spirit was sometimes soothed with gifts, and sometimes restrained by terror; and a military count, with three legions, fixed his permanent and ignominious station in the heart of the Roman provinces. ^{Ref. 123} But no sooner was the vigilance of power relaxed or diverted, than the light-armed squadrons descended from the hills and invaded the peaceful plenty of Asia. Although the Isaurians were not remarkable for stature or bravery, want rendered them bold, and experience made them skilful, in the exercise of predatory war. They advanced with secrecy and speed to the attack of villages and defenceless towns; their flying parties have sometimes touched the Hellespont, the Euxine, and the gates of Tarsus, Antioch, or Damascus; ^{Ref. 124} and the spoil was lodged in their inaccessible mountains, before the Roman troops had received their orders, or the distant province had computed its loss. The guilt of rebellion and robbery excluded them from the rights of national enemies; and the magistrates were instructed by an edict, that the trial or punishment of an Isaurian, even on the festival of Easter, was a meritorious act of justice and piety. ^{Ref. 125} If the captives were condemned to domestic slavery, they maintained, with their sword or dagger, the private quarrel of their masters; and it was found expedient for the public tranquillity to prohibit the service of such dangerous retainers. When their countryman Tarcalissæus or Zeno ascended the throne, he invited a faithful and formidable band of Isaurians, who insulted the court and city, and were rewarded by an annual tribute of five thousand pounds of gold. But the hopes of fortune depopulated the mountains, luxury enervated the hardiness of their minds and bodies, and, in proportion as they mixed with mankind, they became less qualified for the enjoyment of poor and solitary freedom. After the death of Zeno, his successor Anastasius suppressed their pensions, exposed their persons to the revenge of the people, banished them from Constantinople, and prepared to sustain a war, which left only the alternative of victory or servitude. A brother of the last emperor usurped the title of Augustus, his cause was powerfully supported by the arms, the treasures, and the magazines, collected by Zeno; and the native Isaurians must have formed the smallest portion of the hundred and fifty thousand Barbarians under his standard, which was sanctified, for the first time, by the presence of a fighting bishop. Their disorderly numbers were vanquished in the plains of Phrygia by the valour and discipline of the Goths; but a war of six years almost exhausted the courage of the emperor. ^{Ref. 126} The Isaurians retired to their mountains; their fortresses were successively besieged and ruined; their communication with the sea was intercepted; the bravest of their leaders died in arms; the surviving chiefs, before their execution, were dragged in chains through the hippodrome; a colony of their youth was transplanted into Thrace, and the remnant of the people submitted to the Roman government. Yet some generations elapsed before their minds were reduced to the level of slavery. The populous villages of Mount Taurus were filled with horsemen and archers; they resisted the imposition of tributes, but they recruited the armies of Justinian; and his civil magistrates, the proconsul of Cappadocia, the count of Isauria, and the prætors of Lycaonia and Pisidia, were invested with military power to restrain the licentious practice of rapes and assassinations. ^{Ref. 127}

      If we extend our view from the tropic to the mouth of the Tanais, we may observe, on one hand, the precautions of Justinian to curb the savages of Æthiopia, ^{Ref. 128} and, on the other, the long walls which he constructed in Crimea for the protection of his friendly Goths, a colony of three thousand shepherds and warriors. ^{Ref. 129} From that peninsula to Trebizond, the eastern curve of the Euxine was secured by forts, by alliance, or by religion; and the possession of Lazica, the Colchos of ancient, the Mingrelia of modern, geography, soon became the object of an important war. Trebizond, in after-times the seat of a romantic empire, was indebted to the liberality of Justinian for a church, an aqueduct, and a castle, whose ditches are hewn in the solid rock. From that maritime city, a frontier-line of five hundred miles may be drawn to the fortress of Circesium, the last Roman station on the Euphrates. ^{Ref. 130} Above Trebizond immediately, and five days’ journey to the south, the country rises into dark forests and craggy mountains, as savage though not so lofty as the Alps and the Pyrenees. In this rigorous climate, ^{Ref. 131} where the snows seldom melt, the fruits are tardy and tasteless, even honey is poisonous; the most industrious tillage would be confined to some pleasant valleys; and the pastoral tribes obtained a scanty sustenance from the flesh and milk of their cattle. The Chalybians ^{Ref. 132} derived their name and temper from the iron quality of the soil; and, since the days of Cyrus, they might produce, under the various appellations of Chaldæans and Zanians, an uninterrupted prescription of war and rapine. Under the reign of Justinian, they acknowledged the God and the emperor of the Romans, and seven fortresses were built in the most accessible passes, to exclude the ambition of the Persian monarch. ^{Ref. 133} The principal source of the Euphrates descends from the Chalybian mountains, and seems to flow towards the west and the Euxine; bending to the south-west, the river passes under the walls of Satala and Melitene (which were restored by Justinian as the bulwarks of the lesser Armenia), and gradually approaches the Mediterranean sea; till at length, repelled by Mount Taurus, ^{Ref. 134} the Euphrates inclines his long and flexible course to the south-east and the gulf of Persia. Among the Roman cities beyond the Euphrates, we distinguish two recent foundations, which were named from Theodosius and the relics of the Martyrs; and two capitals, Amida and Edessa, which are celebrated in the history of every age.
