Al-Muqawqis
Al-Muqawqis is mentioned in Islamic history as a ruler of Egypt, who corresponded with the Islamic prophet Muhammad. He is often identified with Cyrus, Patriarch of Alexandria, who administered Egypt on behalf of the Byzantine Empire. However, this identification is challenged as being based on untenable assumptions. An alternative view identifies al-Muqawqis with the Sassanid governor of Egypt.
