view goes back to Aristotle, and it has been challenged by modern research. The term Coae vestes seems to refer to a type of silk garment and not the site of production (the island of Kos). The origin of the term is ultimately unclear. Byzantine Era The bishopric of Kos was a suffragan of the metropolitan see of Rhodes. Its bishop Meliphron attended the First Council of Nicaea in 325. Eddesius was one of the minority Eastern bishops who withdrew from the Council of Sardica in about 344 and set up a rival council at Philippopolis. Iulianus went to the synod held in Constantinople in 448 in preparation for the Council of Chalcedon of 451, in which he participated as a legate of Pope Leo I, and he was a signatory of the joint letter that the bishops of the Roman province of Insulae sent in 458 to Byzantine Emperor Leo I the Thracian with regard to the killing of Proterius of Alexandria. Dorotheus took part in a synod in 518. Georgius was a participant of the Third Council of Constantinople in 680–681. Constantinus went to the Photian Council of Constantinople (879). Under Byzantine rule, apart from the participation of its bishops in councils, the island's history remains obscure. It was governed by a droungarios in the 8th–9th centuries, and seems to have acquired some importance in the 11th and 12th centuries: Nikephoros Melissenos began his uprising here, and in the middle of the 12th century, it was governed by a scion of the ruling Komnenos dynasty, Nikephoros Komnenos. Today the ecclesiastical metropolis of Kos remains under the direct authority of the Patriarchate of Constantinople, rather than the Church of Greece, and is also listed by the Catholic Church as a titular see. Genoese Era Following the 11th century, Kos passed under Genoese control, although it was a Byzantine territory and kept for a while by the Empire of Nicaea. Genoese ruled as protectorate and lasted over four centuries. In the 1320s, Kos nominally formed a part of the realm of Genoese Vignolo de Vignoli. The Knights Hospitaller were hosted over the island paying a rent to Genoese republic. From the 14th century onwards the island experienced raids of Turkish corsairs. During this period two towers were built in the southeast and southwest sections of the castle during the raids of Yıldırım Bayezid between 1391 and 1396. Kos faced its
