Arthur's adviser, prophet and magician, is basically the creation of Geoffrey of Monmouth, who in his twelfth century History of the Kings of Britain combined the Welsh traditions about a bard and prophet named Myrddin.

Geoffrey gave his character the name Merlinus rather than Merdinus, because the latter might have suggested to his Anglo Norman audience the vulgar word "merde."

In Geoffrey's book, Merlin assists Uther Pendragon and is responsible for transporting the stones of Stonehenge from Ireland
