Himeria
Himeria was a city and bishopric in the Roman province of Osrhoene, whose metropolitan see was Edessa.History
The city, which was destroyed, has not been rediscovered; but it is thought to have been located near the Euphrates and Europos or Carchemish.
The 6th-century "Notitia" of Anastasius still mentions this episcopal see as being in that province and in the Patriarchate of Antioch. Procopius says that Byzantine Emperor Justinian I rebuilt its walls.
At least seven bishops are known from the 4th to the 6th century, the first of whom, Eustathius, was in correspondence with Saint Basil.
