More than 90 years before Columbus, Prince Henry St Clair of Orkney reached North America with a Venetian captain and 300 colonists. Based on new archaeological evidence, this book confirms Prince Henry's voyage, and details the role played by the outlawed Order of the Knights Templar, revealed here as the antecedents of the Freemasons. This book is both a revision of the history of the discovery of America, and a revelation of the origins of the Masons. Some of the Templars carried their treasure to the St Clair castle where the knights' relics are still buried. The tomb of their St Clair Grand Master, with the grail carved on its stone, lies in Rosslyn, the core chapel of the Masonic movement. Other books by Andrew Sinclair include The Breaking of Bumbo, Gog and King Ludd.
