Located north of Mosul, St. Matthew's Monastery-commonly known as Dayr Sheikh Matti-is perhaps the most ancient religious institution in Iraq. Although the Syriac life story of St. Matthew was published together with that of St. Behnam by Paul Bedjan in 1891, and translated into Arabic by Elias Behnam, this present account is more extensive and informative. It includes in-depth physical and spiritual descriptions of the monastery as an outstanding institution which played a significant role in the history of the Syrian Orthodox Church of the East. Mar Ignatius Jacob III offers insight into the monastery's learned superiors, metropolitans and magnificent library.
