Miss Paton (Studies in the Fairy Mythology of Arthurian Romance, Boston, 1903) establishes Morgain's relations to other romantic heroes such as Ogier, Auberon, Alisandre l'Orphelin, etc.  Notable among these are Morgain's courtship of Lancelot and Guiomar as a result of her natural jealousy of Guenevere.  According to the Livre d'Artus, Morgain is led to build the Val sans Retor, from which as the name implies there is no escape.  As Miss Paton points out, in many cases Morgain was brought into connection with other heroes than Arthur by the fact that Arthur had become popularly known as her brother.  Thus Crestien assures us: ce fu veritez prouvee that her lover was Guiomar.
