Lady Ethel Stefana Drower (1879–1972) studied the Middle East and its cultures. She was considered the primary specialist on the Mandaeans, a gnostic sect, and the chief collector of Mandaean manuscripts. Her works include The Canonical Prayerbook of the Mandaeans (a translation of the Qolusta); The Mandaeans of Iraq and Iran; The Secret Adam (Mandaeans again); and The Peacock Angel (about the Yezidis).
