Saint Damian lived in the thirteenth century. He was a hesychast on Mt. Athos, and struggled in the skete of Esphigmenou monastery, on a mountain called Samareia, between the monasteries of Hilandar and Esphigmenou, and also in one of the caves where the Father of Russian Monasticism, Saint Anthony of the Caves (July 10), had lived in asceticism.
Known for his ascetic life and for the miracles he performed, he was truly obedient and kept the injunctions of the Fathers.
Saint Damian reposed in his cell in the year 1280, and a miraculous fragrance issued from his grave for forty days. His Life was written by his friend Saint Cosmas of Zographou Monastery (September 22).
