'A major breakthrough at last! Knight and Butler's stunning discovery could completely change the way we view our remote past... and origins.' Robert G. Bauval, author of The Orion Mystery 'Absolutely fascinating, and very, very convincing. Knight and Butler's findings provide compelling scientific evidence of the existence of an advanced, technological civilisation in remote antiquity.' Graham Hancock, author of Fingerprints of the Gods

Christopher Knight's first book, The Hiram Key (1996), co-authored with Robert Lomas, became an instant bestseller and has since been translated into 37 languages selling over a million copies worldwide.

He has researched ancient cultures, pagan beliefs and comparative religion and has published four successful books on the Knights Templar and the Grail legend.
