I have spun this thread off from the movie review on to discuss theories and evidence for the proposition that the legendary figure King Arthur was or was not based on one or more historical prototypes. We can also include posts on the various sources for the legends and their comparison. To start off, when I was much younger it was stated that the real Arthur was a certain Artorius or Arctorius who had the title, or was described in some document as, Dux Bellorum ("War Leader" in Latin) who beat the Saxons in a big battle at some Mons Badonicus ("Mt. Badon", not identified with any modern site AFAIK). Comments?
