There are so many different versions (as in the case of the identity of King Arthur), and many of them contradict each other. There is also the problem of the relations of the characters. For example, Mordred is introduced as the incestuous son of King Arthur in most cases, but there are versions where he is presented as Morgan Le Faye's son. One of the reasons may be because of an adaptation for children, but some authors may have blended Morgan Le Faye with her sister Margawse (Britannia web page) - with whom King Arthur is said to have conceived Mordred - in order to make a clear distinction between the forces for and against King Athur. In most versions, Morgan Le Faye's son is Uwayne, who tries to stop his mother from plotting evil. Even Margwse's relation to Arthur differs in version. Some present her and Elayne as Queen Igraine's sisters, whereas others say she and Elayne are Igraine's daughters. Sometimes the characters' relations differ even within the same version. For example, Sir Lyonel is first introduced as Sir Lancelot's nephew, but comes out later as his cousin. The same with Sir Ector de Marys. He is presented as Sir Lancelot's cousin , then as his brother. Why the muddle? Well, the myth on which it is based is a muddle in itself as we can see from its roots.

In the case of this legend, even the little facts that exist can be supported or denied, and that is what distinguishes it from other legends. Take the death of King Arthur. In 1190, monks in Glastonbury claim to have discovered King Arthur's grave. It was even inscribed with his name. Yet, it was still debatable. Some said it was not King Arthur but Sir Lancelot; some said it was just an invention by the monks to draw prestige to their abbey. Some insisted he...
