Odin and Merlin: Threefold death and the world tree
The present work expands upon Donald Ward's work on the Threefold Death in Odinic narratives to demonstrate significant parallels between the myths of the Norse god Odin and the corpus of work concerned with the Welsh wild man Merlin. In both the Norse and Celtic material, the parallels are identified in the motif of sacrifice on the World Tree, along with a form of the Threefold Death, as a means of accessing otherworldly mantic knowledge.
