I just finished "Finding Merlin" and started "Finding Arthur"
Real thought provoking. This solves the mystery of why the actual people and places of King Arthur and the round table can not be found.
Adams premise and proofs place them all in Scotland. Merlin was a druid during the time when the people of the old way were dominant and the church in Rome was converting the isles to it's faith. Since literacy was rare at that time, the church and aristocracy wrote all written history and played fast and loose with the facts, to play down anything of the old ways.
