What is the definition of a wizard? Here we examine the origin of Merlin the wizard and see how he is curiously connected with all later wizards — both imaginary and real — from Faust to Nostradamus, to Doctor John Dee and Sir Edward Kelley — and onto Gandalf, Dumbledore, The Doctor (Who) and even Obi-Wan Kenobi. Also in this episode we look at The Staffordshire Hoard and learn how this discovery might explain dragon gold.
