In many ways, this is an exemplary publication, with detailed description and analysis of an important Byzantine fortification, based on twenty five years meticulous work. Using photogrammetry, the survey produced a plan at 1:50, reproduced here at half scale, in clearly readable foldouts (Tafel 31–46) that enable the phases of building and reconstruction to be easily distinguished. These plates also include detailed drawings of sections and of varying styles of masonry. There are in addition five useful sketch plans (pp.104–108) that (...) sort out the main stages of the fortifications, and abundant illustrations on 30 other plates. This might be enough for normal purposes, but the author has also produced a long and very detailed text that describes all the towers and walls, and sets them in the broader context of the history of the city, and of the development of the art of war. The different phases are presented chronologically, together with the urban and regional history and discussions of dating (pp.1–91), then usefully summarized (pp.93–103). The historical sections form a valuable complement to the material in K. Rheidt, Altertumer von Pergamon XV.2, die byzantinische Wohnstadt (Berlin 1991), which also includes a useful summary of the city's history (pp.241–253). K.'s meticulous analysis leads to several new interpretations and redatings of the walls. Some of these are open to serious question and will probably need revision, especially since K. operates in a curious ignorance or disregard for much modern literature on Byzantine fortifications, and makes poor use of available comparative material.
