Book excerpt: On the great influence of a valiant lord: "The companions, who see that good warriors are honored by the great lords for their prowess, become more determined to attain this level of prowess." On the lady who sees her knight honored: "All of this makes the noble lady rejoice greatly within herself at the fact that she has set her mind and heart on loving and helping to make such a good knight or good man-at-arms." On the worthiest amusements: "The best pastime of all is to be often in good company, far from unworthy men and from unworthy activities from which no good can come." Enter the real world of knights and their code of ethics and behavior. Read how an aspiring knight of the fourteenth century would conduct himself and learn what he would have needed to know when traveling, fighting, appearing in court, and engaging fellow knights. Composed at the height of the Hundred Years War by Geoffroi de Charny, one of the most respected knights of his age, A Knight's Own Book of Chivalry was designed as a guide for members of the Company of the Star, an order created by Jean II of France in 1352 to rival the English Order of the Garter. This is the most authentic and complete manual on the day-to-day life of the knight that has survived the centuries, and this edition contains a specially commissioned introduction from historian Richard W. Kaeuper that gives the history of both the book and its author, who, among his other achievements, was the original owner of the Shroud of Turin.
