Father Afonso Mendes (18 June 1579 – 21 June 1659), was a Portuguese Jesuit theologian, and Patriarch of Ethiopia from 1622 to 1634. While E. A. Wallis Budge has expressed the commonly accepted opinion of this man, as being "rigid, uncompromising, narrow-minded, and intolerant", there are some who disagree with it. The writings of Mendes include Expeditionis Aethiopicae, which describes the customs and conditions of Ethiopia.
