Eighteen small paintings, ten folios, a Gospel book made to be looked at as much as read: the Nestorian Evangelion is a modest object by the standards of illuminated manuscripts generally, and a significant one by the standards of the tradition that produced it. The Church of the East, historically labeled Nestorian by outsiders, is often described as aniconic, wary of pictorial images in a way Byzantine and Latin Christianity were not, and a sixteenth century Gospel book built specifically to carry a cycle of narrative scenes, the Annunciation, the Nativity, the Passion, the Resurrection, the Ascension, Pentecost, the Last Judgment and portraits of the four evangelists, complicates that description rather than confirming it. Scholar Jules Leroy, studying the manuscript's script and layout, proposed that if it once belonged to a larger Gospel book from Mosul, a precise date follows: 1497 in the common calendar, reckoned in the manuscript's own pages by the Seleucid era as the year 1806.
Its captions run in two languages, Syriac and Armenian, small evidence of a community in contact across linguistic lines, and scholarly analysis of the illustrated section has pointed toward the village of WRG in the diocese of Siirt as a possible point of origin, tucked into the same northern Mesopotamian world where the Church of the East had maintained a continuous presence for over a thousand years by the time this book was painted.
