Huntingford identifies it with Dahna, a village 15 miles east of the Tekezé River. G.W.B. Huntingford, The Historical Geography of Ethiopia (London: The British Academy, 1989), p. 74 At the age of 30, Iyasus Mo'a travelled to the monastery of Debre Damo during the abbacy of Abba Yohannis where he was made a monk, and was given arduous tasks by the abbot.
