the lady of the lake has been called by so many names. she was lancelot's foster mother / mother, a sometimes faery queen, and always the keeper of excalibur
arthurian legends inspired quite a lot of romantic art. i find that the stories also make incredibly good leisure reading. they draw from an oratory tradition with a really significant radius-- Ireland to Spain; the celtic reign was far reaching. Marie de France's lais were mostly attributed to Brittany, and they are oh so fantastic.
