Catweazle is a Wizard who lived in the 11th century. By following by the Normen he made a desperate spell and above all it worked. But the only detail he missed was he didn't made the flight he'd prepared as a bird. In spite of that he made a time travel to the 20th century, "Salmy ,Dalmy Adonay". Geoffrey Bayldon is Catweazle. 1970
