Epona, thanks for those posts! My fingers were just itching when I read the first post, but you took all need for an answer out of my hands with your accurate and expert post!
I get to read quite a lot of the research on the subject as well in my study of English Literature. BTW Sir Gawaine and The Green Knight is highly recommendable, there are also modern english translations available. (however if anyone is brave enough to read the original text they earn my respect and can always contact me for help with understanding it!)
