Merlin's Glass Harp : LEGEND
By hilary west
'Transformed by Merlin's potions into the likeness of the absent King Gorlois, Uther Pendragon, king of the Britons, arrives at the gates of Tintagel fortress at twilight. The guard admits whom he takes to be his royal master. That night King Uther spends with Gorlois' Queen Ygerna, whom he loves to distraction. That night she conceives Arthur, most famous of men.'
History of the Kings of Britain, Geoffrey of Monmouth,

So soon as he came on earth, elves took him, they enchanted the child with magic most strong, they gave him insight to be the best of all knights; they gave him another thing, that he should be a rich king; they gave him a third, that he should live long; they gave to him the prince virtues most good, so that he was most generous of all men alive.'
Brut, Layamon, c. 1190
