The growing power of the Catalans under this daring leader, who had marched across “the black bridge” of Negroponte and had occupied two of the most important castles of the island, so greatly alarmed the Venetians that they persuaded King Frederick II of Sicily to curb the restless ambition of his bastard son, lest a European coalition should be formed against the disturber of Greece. Above all else, the Republic was anxious that a Catalan navy should not be formed at the Piræus; and it was therefore stipulated, in 1319, that a plank was to be taken out of the hull of each of the Catalan vessels then lying in “the sea of Athens,” and that the ships’ tackle was to be taken up to “the Castle of Athens” and there deposited[90]. Thus shut out from naval enterprise, Fadrique now extended his dominions by land. The last Duke of Neopatras had died in 1318, and the best part of his duchy soon fell into the hands of the Catalans of Athens, who might claim that they represented the Burgundian dukes, and were therefore entitled to some voice in the government of a land which Guy II had once administered. At Neopatras, the seat of the extinct Greek dynasty of the Angeloi, Fadrique made his second capital, styling himself “Vicar-General of the duchies of Athens and Neopatras.” Thenceforth the Sicilian dukes of Athens assumed the double title which figures on their coins and in their documents; and, long after the Catalan duchies had passed away, the Kings of Aragon continued to bear it. This conquest made the Company master of practically all continental Greece; even the Venetian Marquess of Boudonitza paid an annual tribute of four horses to the Catalan vicar-general[91]. Still, however, the faithful family of Foucherolles held the two great fortresses of Argos and Nauplia for the exiled house of Brienne. Young Walter had now grown up to man’s estate, and it seemed to him that the time had come to strike a blow for the recovery of his Athenian heritage. The Angevins of Naples supported him in their own interest as well as his; Pope John XXII bade the Archbishops of Patras and Corinth preach a crusade against the “schismatics, sons of perdition, and pupils of iniquity” who had seized his patrimony; but the subtle Venetians, who could have contributed more than Angevin aid or papal thunder to the success of his expedition, had just renewed their truce with the Catalans. From that moment his attempt was bound to fail.
