Leo I the Thracian
Phaselis became a Christian bishopric, a suffragan of the metropolitan see of Mira, the capital of the Roman province of Lycia. Its bishop Fronto took part in the Council of Chalcedon in 451. His successor, Aristodemus, was one of the signatories of the letter that in 458 the bishops of Lycia sent to Byzantine Emperor Leo I the Thracian concerning the murder of Proterius of Alexandria. The bishop of the time of the Second Council of Nicaea (787) did not attend, and the acts were signed in his name by a deacon called Ioannes.
