In Malory's "Le Morte d'Arthur", French and English tales were reworked into the definitive mythology of King Arthur and the Knights of the Round Table. But he may have gotten one thing wrong.
Instead of a lady in the lake providing (and eventually taking back) the fabled sword Excalibur, symbol of pre-Norman rule, until the return of the King, the lady in the lake may have been meant to
be the next great monarch. If so, she's arrived
and her name is Saga Vanecek.
