In 1170 A.D., a certain Welsh prince, Madoc ab Owain Gwynedd, sailed away from his homeland, which was filled with war and strife and battles between his brothers. Yearning to be away from the feuds and quarrels, he took his ships and headed west, seeking a better place. He returned to Wales brimming with tales of the new land he found--warm and golden and fair. His tales convinced more than a few of his fellow countrymen, and many left with him to return to this wondrous new land, far across the sea.
George Donald King McCormick (11 December 1911 – 2 January 1998) was a British journalist and popular historian, who also wrote under the pseudonym Richard Deacon.
Deacon presents a poorly researched narrative of Madoc's mythical journey that is riddled with factual errors and flat-out fabricated information. The only positive comment I have is that he does not blindly accept every single piece of evidence for Madoc and is at least somewhat critical.
