Born in Trebizond, he was educated in Constantinople, then entered into ascetic life. Seeking greater reclusion, he went to the Holy Mountain to live in silence. But many others gathered around him, and in time he was forced to build the monastery known as the Great Lavra. As construction was being planned, he beheld the Mother of God, who miraculously brought forth water from a rock near the site, and promised him that she would be the abbess of his monastery. He died when the newly-constructed dome of the monastery collapsed while he and six of his brethren were working on it.
