Geoffrey Ashe's book on this legendary figure offers a succession of surprises. The Merlin of legend was born to be a magician. He was 'immaculately' conceived and was able to interpret dreams and utter prophecies. Even his fate was imbued with magic. Like Arthur, he acquired immortality and sleeps on Bardsey Island, in a subterranean chamber with nine companions. Ashe reveals the man behind the myth, establishing beyond doubt the historicity of a Welsh prophet called Myrddin Emrys. Despite his 'supernatural' status it is Merlin, of all the great characters of the Arthurian world, who has the strongest claim to have existed.
