During this period, monophysitism spread throughout his archdiocese and Barsauma was faced with hostility from many Christians. Struggling to keep his see, Barsawma negotiated with Acacius to keep his seat. After the forced closure of the School of Edessa in 489 by Emperor Zeno, Barsauma welcomed the teachers and students and reopened the School of Nisibis, becoming the key centre for Nestorianism in the East. Barsauma died in 491, according to Bar Hebraeus he was killed by monks from Tur Abdin with the keys of their cells, however he also mentions how his tomb may be found in the Church of Mar Jacob in Nisibis.
