What makes the book extremely fascinating is, first, the rich, comparative—and up to now unexplored—material, consisting of literary and documentary texts mostly in Greek and Latin but also in western European vernaculars, Arabic and Turkish, which cover a remarkably broad geographical area (from the Aegean to Egypt and from Cyprus to Catalonia). Second is the author’s approach, which combines empirical and social-historical elements. [...] This all-around treatment of the subject makes this book valuable to a broad range of scholars who are interested in social, cultural, demographic, and political structures and influences in Byzantine, Crusader, Western Medieval, and Ottoman Studies.
