Renowned for his remarkable architectural works of construction and restoration, Eugène Viollet-le-Duc gives us here a lesser known aspect of his talent: a masterly study of the military customs of the Middle Ages, listing the weapons of this period and their use. The engravings of an exceptional quality illustrating details of each weapon and armor, are accompanied by meticulous descriptions of their handling and functions. More than a dictionary, this work is a true history book, a surprisingly realistic account of the living and fighting conditions of medieval warriors.
