Donuel - Terry Jones, of the Python team, has written a couple of more academic books on medieval subjects and presented some tv programmes about the Crusades, so the Monty Python Holy Grail film contained some great nuggets of Arthurian knowledge! However, I'm not concerned, any more than they were, in the "truth" behind a historic Arthur - that's a whole different research topic. I'm fascinated with "my" story, which preserves traces of Arthurian tales which are less well known in northern Europe and which might give a glimpse into what we've lost by way of oral storytelling tradition. I've also learnt a great deal about the circumstances surrounding the creation of this story, and how easily certain facts get ignored, and the viewpoint altered, depending on a scholar's theories.
Thank you, Howard - I hadn't heard of Dr Daisy Black before your comment, but I shall make a point of getting in touch with her now. I have heard about Rachel Rose Reid, who is also telling a medieval story, but I embarked on this project without knowing about either of them.
