''The biography of Saint Symeon is found in the writings of the monk Anthony, who wrote it in Greek after witnessing the death of Saint Symeon. Another biography was written in Aramaic by two other followers: Symeo, son of Apollon, and Barhtar Barudan. The third source is the "History" of Theodoret, Bishop of Cyrrhus, in 444.''
