Georges Duby, one of this century's great medieval historians, has brought to life with exceptional brilliance and imagination William Marshal, adviser to the Plantagenets, knight extraordinaire, the flower of chivalry. A marvel of historical reconstruction, William Marshal is based on a biographical poem written in the thirteenth century, and offers an evocation of chivalric lifeâthe contests and tournaments, the rites of war, the daily details of medieval existenceâunlike any we have ever seen.
