The trade of the Egyptians had given them very little knowledge of geography. Indeed the whole trade of the ancients was carried on by buying goods from their nearest neighbours on one side, and selling them to those on the other side of them. Long voyages were unknown; and, though the trading wealth of Egypt had mainly arisen from carrying the merchandise of India and Arabia Felix from the ports on the Red Sea to the ports on the Mediterranean, the Egyptians seem to have gained no knowledge of the countries from which these goods came.
They bought them of the Arab traders, who came to Cosseir and the Troglodytic Berenicê from the opposite coast; the Arabs had probably bought them from the caravans that had carried them across the desert from the Persian Gulf; and that these land journeys across the desert were both easier and cheaper than a coasting voyage, we have before learned, from Phila-delphus thinking it worth while to build watering and resting-houses in the desert between Koptos and Berenicê, to save the voyage between Berenicê and Cosseir. India seems to have been only known to the Greeks as a country that by sea was to be reached by the way of the Euphrates and the Persian Gulf; and though Scylax had, by the orders of Darius, dropped down the river Indus, coasted Arabia, and thence reached the Red Sea, this voyage was either forgotten or disbelieved, and in the time of the Ptolemies it seems probable that nobody thought that India could be reached by sea from Egypt. Arrian indeed thought that the difficulty of carrying water in their small ships, with large crews of rowers, was alone great enough to stop a voyage of such a length along a desert coast that could not supply them with fresh water.
The long voyages of Solomon and Necho had been limited to coasting Africa; the voyage of Alexander the Great had been from the Indus to the Persian Gulf; hence it was that the court of Euergetes was startled by the strange news that the Arabian guards on the coast of the Red Sea had found a man in a boat by himself, who could not speak Koptic, but who they afterwards found was an Indian, who had sailed straight from India, and had lost his shipmates. He was willing to show any one the route by which he had sailed; and Eudoxus of Cyzicus in Asia Minor came to Alexandria to persuade Euergetes to give him the command of a vessel for this voyage of discovery. A vessel was given him; and, though he was but badly fitted out, he reached a country, which he called India, by sea, and brought back a cargo of spices and precious stones. He wrote an account of the coasts which he visited, and it was made use of by Pliny. But it is more than probable the unknown country called India, which Eudoxus visited, was on the west coast of Africa. Abyssinia was often called India by the ancients.
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.
In this reign the schools of Alexandria, though not holding the rank which they had gained under Philadelphus, were still highly thought of. The king still gave public salaries to the professors; and Panaretus, who had been a pupil of the philosopher Arcesilaus, received the very large sum of twelve talents, or ten thousand dollars a year. Sositheus and his rival, the younger Homer, the tragic poets of this reign, have even been called two of the Pleiades of Alexandria; but that was a title given to many authors of very different times, and to some of very little merit. Such indeed was the want of merit among the poets of Alexandria that many of their names would have been unknown to posterity had they not been saved in the pages of the critics and grammarians, and pieced together by the skill of nineteenth century investigators.
