AN ILLUSTRATED HISTORY OF THE KNIGHTS HOSPITALLER
by Stephen Dafoe
Lewis Masonic, 2010. £19.99
This richly illustrated book recounts the entire history of the Knights Hospitaller, from their beginnings nine centuries ago to the present day. Founded during the medieval crusades their full name is the Knights of the Order of St John of Jerusalem -to run hospices. They grew in power and royal favour, conquering territories, including the island of Malta, with which they have long been associated, and Rhodes, building formidable castles such as Krak de Chevaliers in the Middle East. For a while they led the fight against the Barbary pirates in the Mediterranean but the increasing power of European nations meant that their territory and powers were gradually taken away in the ensuing centuries but they still survive today.
