In this classic work, Gertrude Bell, based on her time in the region in the early 20th century, presents a picture of Tur Abdin and the surrounding area in terms of its Christian monuments. The text portion of the book includes descriptions of important landmarks with their relevant histories. Naturally, there are a number of references to Syriac literature and secondary sources. A general index and an index of proper names enable readers to quickly locate relevant parts of Bell’s work. Her readable descriptions are accompanied by 40 figures (maps, building layouts, copies of artwork, etc.) and 28 plates, so that those who study the volume will gain a vivid picture of Christian history and activity in this region.
