In these attempts at maritime discovery, and efforts after a cheaper means of obtaining the Indian products, the Greek sailors of Euergetes made a settlement in the island of Dioscorides, now called Socotara, in the Indian Ocean, forty leagues eastward of the coast of Africa; and there they met the trading vessels from India and Ceylon.  This little island continued a Greek colony for upwards of seven centuries, and Greek was the only language spoken there till it fell under the Arabs in the twilight of history, when all the European possessions in Africa were overthrown.  But the art of navigation was so far unknown that but little use was made of this voyage; the goods of India, which were all costly and of small weight, were still for the most part carried across the desert on camels’ backs, and we may remark that at a later period hardly more than twenty small vessels ever went to India in one year during the reigns of the Ptolemies, and that it was not till Egypt was a province of Rome that the trade-winds across the Arabian Sea were found out by Hippalus, a pilot in the Indian trade.  The voyage was little known in the time of Pliny; even the learned Propertius seems to have thought that silk was a product of Arabia; and Palmyra and Petra, the two chief cities in the desert, whose whole wealth rested and whose very being hung upon their being watering-places for these caravans, were still wealthy cities in the second century of our era, when the voyage by the Arabian Sea became for the first time easier and cheaper than the journeys across the desert.

Euergetes had been a pupil of Aristobolus, a learned Jew, a writer of the peripatetic sect of philosophers, one who had made his learning respected by the pagans from his success in cultivating their philosophy; and also of Aristarchus, the grammarian, the editor of Homer; and, though the king had given himself up to the lowest pleasures, yet he held with his crown that love of letters and of learning which had ennobled his forefathers.  He was himself an author, and wrote, like Ptolemy Soter, his Memorabilia, or an account of what he had seen most remarkable in his lifetime.  We may suppose that his writings were not of a very high order; they were quoted by Athengeus, who wrote in the reign of Marcus Aurelius; but we learn little else from them than the names of the mistresses of Ptolemy Philadelphus, and that a flock of pheasants was kept in the palace of Alexandria.  He also wrote a commentary on Homer, of which we know nothing.  When busy upon literature, he would allow his companions to argue with him till midnight on a point of history or a verse of poetry; but not one of them ever uttered a word against his tyranny, or argued in favour of a less cruel treatment of his enemies.
