Another quote about the absolutely absurd story about Henry Sinclair's trip to the USA in 1398 and the consequent ridiculous Clan Gunn Westford Knight myth - 'Westford Knight.... the text detailing this alleged voyage - the so-called Zeno narrative - was not written until 1558 and is widely regarded as being highly spurious.' Being from pages 136-137 of Sean Martin's 'The Knights Templar The HIstory and Myths of the Legendary Military Order'.
For detailed academic discussion as to why the narrative is totally spurious see http://www.alastairhamilton.com/sinclair.htm As well as the narrative being impossible as history, there is also much that is impossible with the story on an historic basis and on an archaeological basis it also has no support. See On a Gunn helping 'discover' North America - 'Sir James Gunn of Clyth Crowner of Caithness' and the 'Westford knight' myth
The Clan Gunn Societies should not support this myth as history as it is not history, but they do...
