EPARCH, an official, a governor of a province of Roman Greece, , whose title was equivalent to, or represented that of the Roman praefectus. The area of his administration was called an eparchy . The term survives as one of the administrative units of modern Greece, the country being divided into nomarchies, subdivided into eparchies, again subdivided into demarchies (see Greece: Local Administration). "Eparch" and "eparchy" are also used in the Russian Orthodox Church for a bishop and his diocese respectively.
