"In the age of chivalry, and in the very year when Caxton published Malory's Morte d'Arthur with its uplifting theme of knightly virtue and purity, England found itself under the heel of a king whose very first act [stripping and parading Richard's corpse] was one of calculated barbarity. By contrast, Richard III's end would prove to represent England's last personification of the monarch as the flower of chivalry: the last king leading his men shoulder to shoulder in battle, but more than that, attempting to curtail the bloodshed by settling the outcome in single combat."
