He was from Samosata in Mesopotamia, and became a monk at the age of twelve. As a young monk he visited St Symeon the Stylite (September 1) to receive his blessing. Years later he moved to the neighborhood of Constantinople at the request of the holy Patriarch Anatolius (July 3), whom he had healed of a deadly ailment through his prayers. For a time Daniel lived in the church of the Archangel Michael at Anaplus, but nine years later St Symeon the Stylite appeared to him in a vision and told him to imitate Symeon's ascesis of living on a pillar. For the remaining thirty-three years of his life the Saint did just that. He stood immovably in prayer regardless of the weather: once after a storm his disciples found him standing covered with ice. He was much loved by several Emperors (including Leo the Great), who sought him out for counsel. He reposed at the age of eighty-four, having lived through the reigns of three Emperors.
