Bartalomewos of Ethiopia was an Abuna, or head of the Ethiopian Orthodox Church from 1398/99 to sometime after 1434; he succeeded Abuna Salama II. His tenure was a period marked by a series of doctrinal disputes in the Church, and at one point Bartalomewos was accused of denying the threefold nature of the Holy Trinity. Emperor Yeshaq appointed a committee to investigate this serious charge, whose members included graduates of the school at Istifanos Monastery in Lake Hayq.
