Catholic Encyclopedia (1913)/Pentacomia
A titular see of Palestine, suffragan of Areopolis or Rabbah. It was never a residential see; the Crusaders mistook the "Descriptio orbis romani" of George of Cyprus, where it is mentioned (ed. Gelzer, 53), for a "Notitia episcopatuum", whereas it is a purely civil document. There is a locality of this name in Arabia (op. cit., 54), and a third in Palæstina Prima, now known as Fendacoumieh, near Samaria. Le Quien has made the same error ("Oriens christianus", III, 773), but without discovering the name of one bishop. The site of Pentacomia seems unknown.
