If the Church is from or not long after the Byzantine era the 10 saints could just be 10 christians from the Crusades (several of which passed by and stopped of at Corfu). The old crusade song.....when the saints go marching in.....springs to mind. Here in the history of Corfu you will see reference to the persecusion of christians...........could there be a link here to the 10 saints? It may not be actually ten but just a number used to represent a small group.
IV. BYZANTINE PERIOD (337-1204 AD)
After the fall of the Roman Empire, Corfu became part of Byzantium. During the Byzantine period, the island was constantly raided by pirates, Goths and Barbarians. When General Velissarios went on an expedition against the Vandals of Africa and the Goths of Italy, Totila's Goths had the opportunity to conquer the island, causing severe damage. After that, there was a period of peace and prosperity during which the island's capital was transferred north and the Old Castle was built. In the 9th century, the "Scheme of Kefalonia" was founded, including all the Ionian islands. Unfortunately, this period of peace ended with the domination by the Cretan Saracenes who caused great destruction to the island. In 1081, Robert Guiscard conquered Corfu after strenuous fights. During the three years that Corfu remained under the Normandian rule, the crusaders constantly raided the island. In 1147, with the consent of the people of the island who were tired of constant battles, the town came under the rule of the Normand Roger B', only to be liberated by the Byzantine emperor Komninos. This period of peace and prosperity did not last long, as in 1199 the pirate Vetrano Cafouri invaded and raided the city of Kerkira. In 1203, the Crusaders passed by the island on their way to Constantinople.
V. DOMINION OF EPIRUS (1214-1266)
THE DYNASTY OF THE ANDEGAVES (1266-1386)
When the Crusaders conquered Constantinople, in 1204, the island of Corfu was ruled by the pirate from Genoa, Vetrano Cafouri. In 1206, the Venetian fleet, led by Cafouri's son, Dadolo, conquered Corfu and killed the pirate and his men. The Venetian rule ended in 1214, when Corfu was included in the Dominion of Epirus, ruled by Michael A' Aggelos Doukas, one of the three independent states in Greece, after the collapse of Byzantium. This was a period of progress and prosperity, a period when the locals and the church were granted certain privileges. During this period, the fortress of Aggelokastro was built on the western part of the island. In 1236, the island of Corfu once again became part of the Dominion of Epirus, as the latter was reconstituted by Manuel B'. In 1266, the island of Corfu came under the rule of the Andegaves dynasty and a period of deterioration and severe authoritarianism began. The Christians were persecuted, the Archbishop was dismissed and many of the orthodox churches were violently converted to catholic churches. In 1294, Philip, the son of Charles B', was declared "Master" of Corfu and its only administrator. The Andegaves dynasty ruled Corfu until 1386 when the Venetian Rule began.
