A legend differs from an historical narrative only in this-that it is without documentary evidence of authenticity. It is the offspring solely of tradition. Its details may be true in part or in whole. There may be no internal evidence to the contrary, or there may be internal evidence that they are altogether false. But neither the possibility of truth in the one case, nor the certainty of falsehood in the other, can remove the traditional narrative from the class of legends. It is a legend simply because it rests on no written foundation. It is oral, and therefore legendary.
