In the author's estimation the only story which does not live up to the claim of the book's title is Laurin, which was included because of its enormous popularity during the Middle Ages. Perhaps the best tale for the purposes of retelling is Heinrich von Kempten, which tells of the hero's quarrel and reconciliation with Otto the Great.
