An international bestseller for over twenty years, this book is an unparalleled serious examination of the activities of the powerful Priory of Sion - a mystical secret society dating back to the early Middle Ages and behind the creation of the Knights Templar. According to the authors, it is the priors who still guard the secret of the location of the Holy Grail, hide the truth about the true life of Jesus Christ, Mary Magdalene and their descendants, and decisively influence the fate of European monarchies and the real balance of power in world politics.

Masters of the Priory were Leonardo da Vinci, Isaac Newton, Sandro Botticelli, Victor Hugo, Nicolas Flamel and Jean Cocteau. The ruling elite of the modern Priory of Sion, in addition to outstanding figures of culture, art and science, also includes many influential politicians, financiers and media representatives.

Possessing solid power and practically unlimited capabilities, the priors firmly and ruthlessly suppress any possibility of leakage information. Therefore, it took the authors of this book many years of work and considerable courage to, by comparing and analyzing a great many historical documents, evidence and facts, lift the veil of secrecy from the Priory of Sion and conclude: if the powerful order manages to carry out its plans, then the world community will have to recognize the new public education, which is a powerful alternative to the existing European Union.

The book became a mega-bestseller and, in addition, it was it that inspired Dan Brown and provided him with the information to write The Da Vinci Code.
