So, what is the origin of the incredible civilization remembered in later times as King Arthur's Britain? A key point we would like to make is that this civilization is likely to have been prehistoric, or 'Roman-Britain'. In the intervening years, Britain was under continuous assualt and even failed to mint its own coins. Hardly a glorious 'Age of Arthur'. More like a struggle for survival! On the contrary, the really glorious times are in the prehistoric age! We suggest that Camolodonum, is Camelot.
