Book of Chivalry

The Book of Chivalry was written by the knight Geoffroi de Charny (c.1306-1356) sometime around the early 1350s. The treatise is intended to explain the appropriate qualities for a knight, reform the behavior of the fighting classes, and defend the chivalric ethos against its critics, mainly in clerical circles.
