Diocese of Tenedus

Tenedos (Τένεδος Tenedhos; Latin Tenedus) or Bozcaada (Bozcaada) is an island, former bishopric and Latin Catholic titular see of Asian Turkey in the northeastern part of the Aegean Sea.

Ecclesiastical history
Tenedos was an Ancient suffragan diocese in the sway of the Patriarchate of Constantinople (ranking third in the Notitiae Episcopatuum of the patriarchate since the 10th century, plausibly in fact already since the ninth) of the Metropolitan Archdiocese of Mytilene. After the Great Schism the Eastern Orthodox Church promoted it to its own metropolitanate in early fourteenth century. By this time Tenedos was part of the but its location made it a key target of the Venetians, the Genoese and the Ottoman Empire. The weakened Byzantine Empire and wars between Genoa and Venice for trade routes made Tenedos a key strategic location. Although in 1304, Andrea Morisco, a Genoese adventurer, backed by a title from the Byzantine emperor Andronikos III, took over Tenedos and later, sensing political tension in the Byzantine empire just before the Second Byzantine Civil War, the Venetians offered 20,000 ducats in 1350 to John V Palaiologos for control of Tenedos, no Latin bishopric was established.

Historically documented Bishops were, according to Lequien's Oriens Christianus :
 * Diodoros, confirming a synodal letter of the Council of Sardica (343/344)
 * Anastasius, deposed in 431 for theological tendency to the heresy Nestorianism
 * Florentius, attending the [Second =] Robber Council of Ephesus in 449 and the Council of Chalcedon in 451; in fact he was (Arch)bishop of Mytilene, who after Anastasius' deposition assumed the care ('apostolic administration') of the bishoprics of Tenedus, Poroselene (Büyük Maden Island ) the Asian coast competence of the Diocese of Lesbos, posting as his representative on Tenedos a Chorbishop, Evelpisto.
