At the time of the Frankish Conquest of the rest of Greece, Monemvasia was already a place of considerable importance. Even if we reject the statement of the fifteenth century historian, Phrantzes[286], himself a native of the place, that the Emperor Maurice had raised it to the rank of the 34th Metropolitan see—a statement contradicted by an ecclesiastical document of 1397—we know at least that it was even then the seat of a Greek bishopric, whose holder remained a suffragan of Corinth[287] till the Latins captured the latter city in 1210. The Comneni had confirmed the liberties of a community so favourably situated, and the local aristocracy of Monemvasia enjoyed the privilege of self-government. Thanks to the public spirit of its inhabitants, the wisdom of the local magnates, and the strength of its natural defences, which made it in the Middle Ages the Gibraltar of Greece, it had repelled the attack of the Normans from Sicily in the middle of the twelfth century. Fifty years later it was a busy sea-port town, whose ships were seen at the Piræus by Michael Akominatos, the last Metropolitan of Athens before the Conquest, and whose great artistic treasure, the famous picture of Our Lord being “dragged,” which has given its name to the Ἑλκόμενος church, attracted the covetousness of the Emperor Isaac II[288]. As might have been expected from its position and history, Monemvasia was the last spot in the Peloponnese to acknowledge the Frankish supremacy. Geoffroy I Villehardouin had contented himself perforce with sending a body of troops to raid the country as far as the causeway, or μόνη ἔμβασις, which leads to the great rock-fortress and from which its name is derived[289]; and his son Geoffroy II seems to have meditated the conquest of the place[290]; but it was reserved for the third of the Villehardouins, soldierly Prince William, to hoist the _croix ancrée_ of his family over the “sacred rock” of Hellenism, which was in uninterrupted communication by sea with the successor of Byzantium, the Greek Emperor of Nice[291], and was therefore a constant source of annoyance to the Franks of the Peloponnese. The Prince, after elaborate preparations, began the siege not long after his accession in 1246. He summoned to his aid the great vassals of the Principality—Guy I of Athens, who owed him allegiance for Nauplia and Argos; the three barons of Eubœa; Angelo Sanudo, Duke of Naxos, with the other lords of the Cyclades, and the veteran Count Palatine of Cephalonia, Matteo Orsini, ruler of the island-realm of Odysseus[292]. But the Prince of Achaia saw that without the naval assistance of Venice, which had taken care that his principality should not become a sea-power, he could never capture the place. He accordingly obtained the aid of four Venetian galleys, and then proceeded to invest the great rock-fortress by land and water. For three long years the garrison held out, “like a nightingale in its cage,”
