Marion Zimmer Bradley's novel The Mists of Avalon is different from the usual episodic versions of the Arthurian legend in that it has the structural unity that the label "novel" implies. The narrative is set in fifth-century Britain, a time of religious conflict between Christianity and the native religions of Britain, especially the Mother Goddess cult. Bradley pulls elements from the Arthurian legend and fits them into this context of religious struggle for influence. She draws interesting family relationships which are closely tied to Avalon, the center of Goddess worship. The author also places the major events during Arthur's reign into the religious setting. The Grail's appearance at Camelot and the subsequent events led to the end of the religious struggle, for Christianity emerged victorious.
