Saint Barbara (Greek: Αγία Βαρβάρα), Feast Day December 4, known in the Eastern Orthodox Church as the Great Martyr Barbara, was an early Christian saint and martyr. Accounts place her in the 3rd century in Nicomedia, present-site Turkey or in Heliopolis of Phoenicia, present-day Lebanon. There is no reference to her in the authentic early Christian writings nor in the original recension of Saint Jerome's martyrology.
