Ephraim of Nea Makri, Greek martyr and saint (d. 1426)
St. Ephraim the martyr or St. Ephraim of Mount Amomon (Greek: Άγιος Εφραίμ ο μάρτυρας / του Όρους των Αμώμων), believed to have lived from 1384 to 1426, is venerated as a martyr and miracle-working saint by Ecumenical Patriarchate of Constantinople and Greek Orthodox Church. His status as a saint is controversial, as there are no sources testifying to his existence as an historical person. Believers regard him as a "newly revealed" ("νεοφανής") saint, whose existence is a matter of divine revelation rather than historical proof.
