The Life Story of Saint Demiana and the 40 Virgins is found in two Arabic sources: Synaxarium and Life Story of the Chaste Saint Demiana and History of the Monastery. The life story was translated from Arabic into English by the nuns of Saint Demiana’s Monastery in Egypt. The book, Life Story of the Chaste Saint Demiana and History of the Monastery, is taken from 18th century manuscripts written by Bishop John (Bishop of El-Borollos); these manuscripts were transcribed from older manuscripts dated in the 6th century during the apostolic service of Dimianos (563-598 A.D., 35th Patriarch of the See of St. Mark), and were originally transcribed from ancient manuscripts written by Christodoulou, the disciple of Saint Julius El-Akfahsee (4th century).
