Catholic Encyclopedia (1913)/Himeria
A titular see in the province of Osrhoene, suffragan of Edessa. The "Notitia" of Anastasius, in the sixth century, still mentions this see as being in that province and in the Patriarchate of Antioch ("Echos d'Orient", Paris, 1907, 145). Procopius ("De Ædificiis", II, 9) says that Justinian rebuilt its walls. At least seven bishops are known from the fourth to the sixth century, the first of whom, Eustathius, was in correspondence with St. Basil (Lequien, "Oriens Christ.", II, 983-86). The city, which was destroyed, has not been rediscovered; but it is thought to have been located near the Euphrates and Europos or Djerabis.
