Felix of Byzantium

Saint Felix was bishop of Byzantium between 136 and 141, in the time of the emperors Hadrian and Antoninus Pius. He succeeded Eleutherius, and after him came Polycarp II. Most sources say he shepherded five years. His feast is on 15 April.

It is said that he was buried in the church of Argyropolis, like his predecessors; according to another source his relics are in the underground cave in which the Apostle Andrew is said to have founded an altar. No other details of his life are known; some scholars regard the detailed list of the first bishops of Byzantium up to Metrophanes as a late construction, made to prove the apostolic origin of the see of Constantinople.
