History
In college, I wrote a paper on King Arthur as the final exam for a class on Winston Churchill. (My professor was a wise man who justly rewarded my insights - and charitably resisted the likely instinct to fail me.) The exact historicity of the ancient king pales in importance to his legend and legacy as the quintessential British ruler.
However, any hint that the legends are true is a welcome revelation. The London Telegram reports "King Arthur's round table may have been found by archaeologists in Scotland."
Archaeologists searching for King Arthur's round table have found a "circular feature" beneath the historic King's Knot in Stirling.
Ultimately true or not, any reason to reflect upon a more noble and disciplined Britain - particularly in these days of looters and hooligans - is a good thing..
Oh, I think there was an "Arthur" of some kind, but alas, he would bear only a faint resemblance to the man in the myth. The Celts have always had a funny way of losing cultural wars and then making up glorious pasts as a sort of consolation prize (e.g., the Civil War).
