Ten of the articles in this volume focus on the Dodecanese islands, mainly Rhodes, at the time of their rule by the Hospitallers during the period 1306–1522. Scholarly and popular interest in the military orders has grown substantially over the last twenty years, but comparatively little has been written about the Hospitaller Dodecanese. What distinguishes this work is the author’s use of hitherto unpublished documents from the Hospitaller archives in Malta and his assiduous field work on the island sites discussed. Heslop’s work on the Hospitallers on the island of Rhodes has also enabled him to put together an important gazetteer of place-names in the countryside of Rhodes, published here for the first time. The remaining two chapters of the collection summarize ground-breaking detective work to locate Villehardouin’s ‘lost’ castle of Grand Magne in the Mani, and present a wider study of Byzantine fortifications in medieval Greece. This book will appeal to scholars and students of medieval history, and to all those interested in the history of the Hospitallers. (CS1093).
