Among the incidents occurring during the struggles between the Egyptian and Babylonian kings there is one deserving to be brought into conspicuous prominence, from the importance of its consequences in European history. It was the taking of Tyre by Nebuchadnezzar. So long as that city dominated in the Mediterranean, it was altogether impossible for Greek maritime power to be developed. The strength of Tyre is demonstrated by her resistance to the whole Babylonian power for thirteen years, "until every head was bald and every shoulder peeled." The place was, in the end, utterly destroyed. It was made as bare as the top of a rock on which the fisherman spreads his nets. The blow thus struck at the heart of Tyrian commerce could not but be felt at the utmost extremities. "The isles of the sea were troubled at her departure." It was during this time that Greece fairly emerged as a Mediterranean naval power. Nor did the inhabitants of New Tyre ever recover the ancient position. Their misfortunes had given them a rival. A re-establishment in an island on the coast was not a restoration of their supremacy. Carrying out what Greece instinctively felt to be her national policy, one of the first acts of Alexander's Asiatic campaign, two hundred and fifty years subsequently, was the siege of the new city, and, after almost superhuman exertions, its capture, by building a mole from the mainland. He literally levelled the place to the ground; a countless multitude was massacred, two thousand persons were crucified, and Tyrian influence disappeared for ever. [Sidenote: Foreign epochs in Greek history.] In early Greek history there are, therefore, two leading foreign events: 1st, the opening of the Egyptian ports, B.C. 670; 2nd, the downfall of Old Tyre, 573. The effect of the first was chiefly intellectual; that of the second was to permit the commencement of commercial prosperity and give life to Athens.
