1. Bishopric of Erythrae
Erythrae, a city on the western coast of Asia Minor, across the island of Chios, was a bishopric see of the province of Asia, subjected to the metropolis of Ephesus. The ecclesiastical see is also known as bishopric of Erythraea or Erythra. There is evidence on the see from at least as early as the first half of the 5th century, since the bishops of Erythrae participated in the Third Ecumenical Council (431), the Fifth Ecumenical Council (553), the Seventh Ecumenical Council (787) and the Council of 869, while in the Fourth Ecumenical Council (451) the bishop of Erythrae was represented by the metropolitan of Ephesus. Bishops of the city are also known in the 12th and 13th centuries until 1230, most of them thanks to their seals. The bishopric should have been preserved until the end of the 13th century, since the last reference to a bishop of Erythrae occurs in 1292.1
