the Volga. A fortress, designed by Alexander perhaps, or one of his successors, to command that important pass, had descended by right of conquest or inheritance to a prince of the Huns, who offered it for a moderate price to the emperor; but while Anastasius paused, while he timorously computed the cost and the distance, a more vigilant rival interposed, and Cabades forcibly occupied the Straits of Caucasus. The Albanian and Iberian gates excluded the horsemen of Scythia from the shortest and most practicable roads, and the whole front of the mountains was covered by the rampart of Gog and Magog, the long wall which has excited the curiosity of an Arabian caliph and a Russian conqueror. According to a recent description, huge stones, seven feet thick, and twenty-one feet in length or height, are artificially joined without iron or cement, to compose a wall, which runs above three hundred miles from the shores of Derbend, over the hills, and through the valleys of Daghestan and Georgia. Without a vision, such a work might be undertaken by the policy of Cabades; without a miracle, it might be accomplished by his son, so formidable to the Romans, under the name of Chosroes; so dear to the Orientals, under the appellation of Nushirwan. The Persian monarch held in his hand the keys both of peace and war; but he stipulated, in every treaty, that Justinian should contribute to the expense of a common barrier, which equally protected the two empires from the inroads of the Scythians.

VII. Justinian suppressed the schools of Athens and the consulship of Rome, which had given so many sages and heroes to mankind. Both these institutions had long since degenerated from their primitive glory; yet some reproach may be justly inflicted on the avarice and jealousy of a prince, by whose hand such venerable ruins were destroyed.

Athens, after her Persian triumphs, adopted the philosophy of Ionia and the rhetoric of Sicily; and these studies became the patrimony of a city, whose inhabitants, about thirty thousand males, condensed, within the period of a single life, the genius of ages and millions. Our sense of the dignity of human nature is exalted by the simple recollection, that Isocrates was the companion of Plato and Xenophon; that he assisted, perhaps with the historian Thucydides, at the first representation of the dipus of Sophocles and the Iphigenia of Euripides; and that his pupils Æschines and Demosthenes contended for the crown of patriotism in the presence of Aristotle, the master of Theophrastus, who taught at Athens with the founders of the Stoic and Epicurean sects. The ingenuous youth of Attica enjoyed the benefits of their domestic education, which was communicated without envy to the rival cities. Two thousand disciples heard the lessons of Theophrastus; the schools of rhetoric must have been still more populous than those of philosophy; and a rapid succession of students diffused the fame of their teachers as far as the utmost limits of the Grecian language and name. Those limits were enlarged by the victories of Alexander; the arts of Athens survived her freedom and dominion; and the Greek colonies which the Macedonians planted in Egypt, and scattered over Asia, undertook long and frequent pilgrimages to worship the Muses in their favorite temple on the banks of the Ilissus. The Latin conquerors respectfully listened to the instructions of their subjects and captives; the names of Cicero and Horace were enrolled in the schools of Athens; and after the perfect settlement of the Roman empire, the natives of Italy, of Africa, and of Britain, conversed in the groves of the academy with their fellow-students of the East. The studies of philosophy and eloquence are congenial to a popular state, which encourages the freedom of inquiry, and submits only to the force of persuasion. In the republics of Greece and Rome, the art of speaking was the powerful engine of patriotism or ambition; and the schools of rhetoric poured forth a colony of statesmen and legislators. When the liberty of public debate was suppressed, the orator, in the honorable profession of an advocate, might plead the cause of innocence and justice; he might abuse his talents in the more profitable trade of panegyric; and the same precepts continued to dictate the fanciful declamations of the sophist, and the chaster beauties of historical composition. The systems which professed to unfold the nature of God, of man, and of the universe, entertained the curiosity of the philosophic student; and according to the temper of his mind, he might doubt with the Sceptics, or decide with the Stoics, sublimely speculate with Plato, or severely argue with Aristotle. The pride of the adverse sects had fixed an unattainable term of moral happiness and perfection; but the race was glorious and salutary; the disciples of Zeno, and even those of Epicurus, were taught both to act and to suffer; and the death of Petronius was not less effectual than that of Seneca, to humble a tyrant by the discovery of his impotence. The light of science could not indeed be confined within the walls of Athens. Her incomparable writers address themselves to the human race; the living masters emigrated to Italy and Asia; Berytus, in later times, was devoted
