Yohannes, Abunä, was a Metropolitan of Ethiopia consecrated by Jacob, Patriarch of Alexandria from 819 to 830 A.D. Christian Arabic sources relate that during the Patriarchate of the latter's successor Joseph, Patriarch from 830 to 849, a war in Ethiopia brought about a popular uprising which forced Yohannes to flee to Alexandria, while another was appointed abun, contrary to the canon. The miseries of Ethiopia increased with a plague, a drought and a succession of defeats for the Emperor, to the point where he had to ask Joseph for a new abun. Yohannes, who had entered the monastery of Baramus, was sent back to Ethiopia under escort, and seems to have been accepted by the people. Later they insisted that he should be circumcised like them, or leave the country, and when he reluctantly submitted to the operation, by a miracle it was found that he was already circumcised.
