Taliesin is portrayed in celtic myths as a singer/storyteller/poet/seer.
In Marion Zimmer Bradley's Mists of Avalon, she identified Merlin as taliesin (not historically accurate, but I love the symbolism).
Best known today as a wizard, a mystic, taliesin (merlin) has and can take many forms and lives in tune with nature; an instrument of the Goddess, as are we all.
Changed the spelling to 'talesin'.
PS, it's also the name of Frank Lloyd Wright's most famous home, but that has nothing to do with my handle.
