Dhu Nuwas
After spending twelve years at the court of king Ella Amida of Axum, he set out with his companion, the nun Edna, to found Debre Damo. Later in his life, king Kaleb is said to have sought his advice before setting out to south Arabia against the Jewish king Dhu Nuwas. He was a disciple of the famous Coptic monk Pachomius the Great who is regarded a founder of Cenobitic Monasticism.
