The History of the Decline and Fall of the Roman Empire - Edward Gibbon [1270]
[Footnote 140: The imaginary rampart of Gog and Magog, which was seriously explored and believed by a caliph of the ninth century, appears to be derived from the gates of Mount Caucasus, and a vague report of the wall of China, (Geograph. Nubiensis, p. 267 - 270. Memoires de l'Academie, tom. xxxi. p. 210 - 219.)]
[Footnote 141: See a learned dissertation of Baier, de muro Caucaseo, in Comment. Acad. Petropol. ann. 1726, tom. i. p. 425 - 463; but it is destitute of a map or plan. When the czar Peter I. became master of Derbend in the year 1722, the measure of the wall was found to be 3285 Russian orgyioe, or fathom, each of seven feet English; in the whole somewhat more than four miles in length.]

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 ^143 was the companion of Plato and Xenophon; that he assisted, perhaps with the historian Thucydides, at the first representation of the Oedipus of Sophocles and the Iphigenia of Euripides; and that his pupils Aeschines 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. ^144 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; ^145 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
