Arthurian literature is a tricky thing. While the general image of King Arthur, Merlin, and Camelot have been ingrained in the minds of most anglophone people, there is no real "canon" of authoritative versions of the legends in the way there is a Shakespearian canon. While the most familiar version of Arthur began with England's Geoffrey of Monmouth in the 12th century, Welsh and Breton sources date even further back. After Geoffrey, French and English-language authors wrote their own adaptations, including Chrétien de Troyes, who introduced the Grail Quest, and most pertinent to this discussion, the anonymous author of the Middle English poem
Sir Gawain and the Green Knight. Each new version adds something to the legend, resulting in hundreds of different plots and variations on them, often contradictory characterizations, and no "correct" version of whatever story a modern bard will present. Even I, a certified The Book Was Better Than The Movie Snob, must admit that any adaptation of the Matter of Britain will be both its own thing and an addition to the ever-evolving state of Arthurian fiction.
Enter The Green Knight.
