A look at the mythical roots in art and literature of Merlin - magician, hero and historical mystery.
Since making his first appearance in 12th century book 'The History of the Kings', Merlin has continued to influence storytelling, music, film and television. Tolkien's Gandalf and J.K Rowling's Dumbledore are just two fictitious figures modelled on the legend.
Merlin - The Legend looks at Merlin's vast cultural influence, not only in Wales, the Celtic world and the British Isles but across the globe.
The documentary is directed by Dylan Richards and produced by William Gruffydd Edwards, executive producer Phil George. It screened on BBC 2 Wales, 20 September 2008.
