Ephraim of Mount Amomon (Greek: ????? ?f?a?µ ??a? ?????? / t?? ????? t?? ?µ?µ??), 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" ("?e?fa???") saint, whose existence is a matter of divine revelation rather than historical proof.
