Since the decease of Robert Guiscard, the Normans had relinquished above sixty years their hostile designs against the Empire of the East. The policy of Roger solicited a public and private union with the Greek princes, whose alliance would dignify his real character; he demanded in marriage a daughter of the Comnenian family, and the first steps of the treaty seemed to promise a favourable event. But the contemptuous treatment of his ambassadors exasperated the vanity of the new monarch; and the insolence of the Byzantine court was expiated, according to the laws of nations, by the sufferings of a guiltless people. With a fleet of seventy galleys, George, the admiral of Sicily, appeared before Corfu; and both the island and city were delivered into his hands by the disaffected inhabitants, who had yet to learn that a siege is still more calamitous than a tribute. In this invasion, of some moment in the annals of commerce, the Normans spread themselves by sea, and over the provinces of Greece; and the venerable age of Athens, Thebes, and Corinth was violated by rapine and cruelty. The silk-weavers of both sexes, whom George transported to Sicily, composed the most valuable part of the spoil; and in comparing the skilful industry of the mechanic with the sloth and cowardice of the soldier, he was heard to exclaim, that the distaff and loom were the only weapons which the Greeks were capable of using. The progress of this naval armament was marked by two conspicuous events, the rescue of the king of France, and the insult of the Byzantine capital. In his return by sea from an unfortunate crusade, Louis VII was intercepted by the Greeks, who basely violated the laws of honour and religion. The fortunate encounter of the Norman fleet delivered the royal captive; and after a free and honourable entertainment in the court of Sicily, Louis continued his journey to Rome and Paris.
