The discovery of a tombstone built by his ancestors set Andrew Sinclair on a trail that was to lead to major re-assessments, not only of our understanding of the discovery of America, but also of the origins of the Freemasons and their role in world history. Based on stunning new archaeological evidence, both in the UK and the USA, The Sword and the Grail details the part played by the Order of the Knights of the Templar - here proved to be the true antecedents of the Freemansons - in the discovery of America. As they fled the authorities who wished to destroyed them, some of the outlawed Templars carried their treasure to St Clair Castle, where the knights' relics are still buried. The tomb of their St Clair Grand Master, with the Grail carved on his stone, lies in Rosslyn, the core chapel of the Masonic movement. With the help of the sea skills and wealth of the Templars, the St Clair Grand Master, tried to found a new Jerusalem in the New World, landing with 300 colonists, first in what is now Nova Scotia and then in New England, more than 90 years before Columbus.
