"The importance of this unusual study is twofold. First, it places the material remains of the medieval peoples of the Pontos in their historical and environmental setting through a sequence of local histories. Second, it is a field record - usually the first and all too often the last - of over three hundred sites and monuments examined by the authors since 1957." Volume one contains the text of this massive study - 394 pages in all with dozens of line drawings and maps. Volume two contains all of the plates - 290 in total. A very clean, bright and solid two volume set of this important study.
