"""[W]ithout doubt a stimulating and significant contribution to the field, not just of Byzantine history in general, but to the history and evolution of medieval fortification and military technology more broadly. It will be useful for specialists of the Byzantine world as well as those from neighboring fields of historical study.""-- ""Bryn Mawr Classical Review"" ""...a big help for those wishing to recreate [fortifications] in scale on the tabletop. It's a magnificent and inspirational survey.""-- ""HGMS"""
