'[This study] provides a highly thought-provoking analysis that will be of interest both to art historians and to scholars researching cross-cultural exchange during this era. It sheds light on matters as diverse as the cult of saints, crusading propaganda, commerce and international politics. More importantly, it describes a long-term trajectory for the development of 'Crusader Art' across Italy and many areas of the eastern Mediterranean that encompasses and informs a whole range of developments, whether artistic, political, military, commercial or cultural. Elegantly written and enriched with many colour photographs, it represents a major addition to scholarship in this field.' Nicholas Morton, Al-Masaq
