Ephraim of Nea Makri was a 15th-century martyr whose life and identity are understood through divine revelation. Born Konstantinos Morphes in 1384, he lived as a monk at a monastery on Mount Amomon in Attica. Following the destruction of his monastery by Ottoman forces, he lived as a hermit before being captured and tortured to death in 1426. While his historical existence lacks traditional documentation, he is venerated as a newly revealed saint by the Greek Orthodox Church and the Ecumenical Patriarchate.
