Of course 'prehistory' ends later in Scotland and Ireland - and to an extent in Wales.

Aren't most accounts of England foreign ones until the times of the great monateries? This brings us to near the Viking raids as being 'locally' historical. I'm not sure how much you can trust the Roman version of history as there is no doubt a great deal of propoganda in there - the barbarian image etc.

Certainly Caesar's accounts differ greatly from Claudius' 100 (?) years later. Old Clavdivs seems to have been more honest, but then he brought f*cking elephants across! You can be honest when your charging at people on elephants!
