Leo I the Thracian
Olympus became a Christian bishopric, a suffragan of the metropolitan see of Myra, the capital of the Roman province of Lycia. Its earliest recorded bishop was Saint Methodius of Olympus, whose service at the head of church in Olympus extended from the late 3rd century to his martyrdom in about 311. Aristocritus was at the Council of Ephesus in 431 and the Council of Chalcedon in 451. Anatolius was a signatory of the joint letter that the bishops of Lycia sent in 458 to Byzantine Emperor Leo I the Thracian regarding the murder of Proterius of Alexandria. Ioannes took part in the synod convoked in 536 by Patriarch Menas of Constantinople.
