The Scots are a fearful people. So fearful that they should be kept out of the empire at all cost. At least they were in Roman times. Known simply as the ‘Barbarians’ to the Romans, like all people outside their large empire, the Scots were a bridge too far. Emperor Hadrian built a wall to protect the Northern end of the empire from the Scots, just north of the Tyne river, around the year 122 AD.
