(M215) The most ancient colonies were Utica and Carthage, built in what is now called the gulf of Tunis; and Cades, now Cadiz, was prosperous one thousand years before the Christian era. The enterprising mariners of Tyre coasted beyond the pillars of Hercules without ever losing sight of land. The extreme productiveness of the southern region of Spain in the precious metals tempted the merchants to that distant country. But Carthage was by far the most important centre for Tyrian trade, and became the mistress of a large number of dependent cities. When Psammetichus relaxed the jealous exclusion of ships from the mouth of the Nile, the incitements to traffic were greatly increased, and the Phœnicians, as well as Ionian merchants, visited Egypt. But the Phœnicians were jealous of rivals in profitable commerce, and concealed their tracks, and magnified the dangers of the sea. About the year 600 B.C., they had circumnavigated Africa, starting from the Red Sea, and going round the Cape of Good Hope to Gades, and from thence returning by the Nile. (M216) It would seem that Nechos, king of Egypt, anxious to procure a water communication between the Red Sea and the Mediterranean, began digging a canal from one to the other. In the prosecution of this project he dispatched Phœnicians on an experimental voyage round Libya, which was accomplished, in three years. The mariners landed in the autumn, and remained long enough to plant corn and raise a crop for their supplies. They reached Egypt through the Straits of Gibraltar, and recounted a tale, which, says Herodotus, “others may believe it if they choose, but I can not believe, that in sailing round Libya, they had the sun on their right and—to the north.” In going round Africa they had no occasion to lose sight of land, and their vessels were amply stored. The voyage, however, was regarded as desperate and unprofitable, and was not repeated. Besides the trade which the Phœnicians carried on along the coasts, they had an extensive commerce in the interior of Asia. But we do not read of any great characters who arrested the attention of their own age or succeeding ages, Phœnician history is barren in political changes and great historical characters, as is that of Carthage till the Roman wars. (M217) Between the years 700 and 530 B.C., there was a great decline of Phœnician power, which was succeeded by the rise of the Greek maritime cities. Nebuchadnezzar reduced the Phœnician cities to the same dependence that the Ionian cities were reduced by Crœsus and Cyrus. The opening of the Nile to the Grecian commerce contributed to the decline of Phœnicia. But to this country the Greeks owed the alphabet and the first standard of weights and measures.
