Such was the state of affairs when, in 1146, Guiscard’s nephew, King Roger of Sicily, availing himself of an insult to his honour, invaded Greece with far greater success than had attended his uncle. The Sicilian Admiral, George of Antioch, occupied Corfù, with the connivance of the poorer inhabitants, who complained of the heavy taxation of the Imperial Government which in the twelfth century levied from that one Ionian Island about 9,000,000 _dr._ of modern money, or more than the present Greek Exchequer raises from all the seven, but was repulsed by the bold inhabitants of the impregnable rock of Monemvasia; then, after plundering the west coast, he landed his troops at the modern Itea, on the north of the Gulf of Corinth, and thence marched past Delphi on Thebes, at that time the seat of the silk manufacture. The city was undefended, but that did not save it from the rapacity of the Normans. Alexander the Great had, at least, spared “the house of Pindaros” when he took Thebes; but its new conquerors left nothing that was of any value behind them. After they had thoroughly ransacked the houses and churches they made the Thebans swear on the Holy Scriptures that they had concealed nothing, and then departed, dragging with them the most skilful weavers and dyers so as to transfer the silk industry to Sicily. This last was a serious blow to the monopoly of the silk trade which Greece had hitherto enjoyed so far as Christian States were concerned. The secret of the manufacture had been jealously guarded; and the fishers who obtained the famous purple dye for the manufacturers were a privileged class, exempted from the payment of military taxes. Roger was well aware of the value of his captives; he established them and their families at Palermo, and at the conclusion of the war they were not restored to their homes in Greece. But the art of making and dyeing silk does not seem to have died out at Thebes, which, fifteen years after the Norman invasion, had recovered much of its former prosperity. When the Jewish traveller, Benjamin of Tudela, visited it about 1161, he found 2000 of his co-religionists there, among them the best weavers and dyers in Greece, and towards the end of the century forty garments of Theban silk were sent as a present by the Emperor to the Sultan of Iconium. Although there are no silks now manufactured at Thebes and no mulberry-trees there, the plain near the town is still called by the peasants _Morokampos_, from the mulberry-trees which once grew upon it. From Thebes the Normans proceeded to the rich city of Corinth, which fell into their hands without a blow. Those who have ascended the grand natural fortress of Akrocorinth may easily understand the surprise of the warlike Normans at its surrender by the cowardly Byzantine commandant. “If Nikephoros Chalouphes”—such was his name—“had not been more timid than a woman,” exclaimed the Sicilian admiral, “we should never have entered these walls.” The town below
