saviours, for the benefit of sailors." In process of time the mortar wore off, the first inscription disappeared along with it, and the second inscription became visible. The erection of the tower of Pharos was by no means the only service the first Ptolemy did to commerce; throughout all his reign he manifested great attention to it and maritime affairs, as well as to those sciences by which they might be improved and advanced. As soon as he had made himself master of Palestine, Syria, and Phoenicia, he turned his thoughts to the conquest of Cyprus: this island abounded in wood, of which Egypt was almost destitute; and on this account, as well as on account of its situation, in the bosom, as it were, of the Levant, it was of the utmost importance to a maritime power. He succeeded in obtaining possession of this valuable island, and thus improved and enlarged the commercial advantages of Egypt. His next step, with this view, was to invite the sailors of Phoenicia to his new capital. His increasing power, especially at sea, roused the envy of Antigonus, who, by extraordinary exertions, in the course of twelve months built and equipped a fleet, which was able to cope with the naval power of Ptolemy. It is foreign to our purpose to notice the wars between them, except in so far as they are connected with the commercial history of Alexandria. This city was benefited by these wars, for Antigonus, in his progress, had driven many of the inhabitants of Syria, Palestine, and Phoenicia from their native lands: to these Ptolemy gave great encouragement, and extraordinary privileges and immunities, which induced them to settle in Alexandria, where they followed their mercantile or commercial pursuits. The report of these advantages granted to foreigners, led Jews, Greeks and Macedonians to flock to Egypt, by which means the population and wealth of that country, and particularly of its capital, were greatly augmented. The foundation of the museum and library of Alexandria, both of which contributed so essentially to science and to the establishment of the Alexandrian school of philosophy, which, as we shall afterwards perceive, produced men that greatly advanced geographical knowledge, is another proof of the wise and comprehensive character of Ptolemy's mind.
