Tricked into a liaison with the Fisher King's daughter Elaine, he becomes the father of Galahad, the Grail winner, and, as a result of the queen's jealous anger at his relations with the lady, goes mad, and remains an exile from the court for some years.
It is not improbable that it represents a free and individual working over of the original Fescamp version, and that in its later shape it was intended to form, and did at one time form, the Quest section of the cyclic redaction of the Arthurian prose romances, being dislodged from this position by the Galahad Quese.
There is good ground for believing that as Grail quester and winner, Gawain preceded alike Perceval and Galahad, and that the solution of the mysterious Grail problem is to be sought rather in the tales connected with the older hero than in those devoted to the glorification of the younger knights.
A knightly celibate, his stainless life, his ardour, caused him to be termed a Yankee Galahad; a pure and simple heart was laid bare to those who loved him in " My Psalm," " My Triumph " and " An Autograph."
- The Quete du Saint Graal, the only romance of which Galahad is the hero, is dependent on and a completion of the Lancelot development of the Arthurian cycle.
Hence the invention of Galahad, son to Lancelot by the Grail king's daughter; predestined by his lineage to achieve the quest, foredoomed, the quest achieved, to vanish, a sacrifice to his father's fame, which, enhanced by connexion with the Grailwinner, could not risk eclipse by his presence.
Introductory to the Galahad quest, and dealing only with the early history, is the Grand Saint Graal, a work of interminable length, based upon the Joseph of Arimathea, which has undergone numerous revisions and amplifications: its precise relation to the Lancelot, with which it has now much matter in common, is not easy to determine.
