Dhe secrets, which could have precipitated the evolution of mankind, have been kept hidden for millennia, for fear that their revelation would cause a cataclysm. These secrets were held by men of great wisdom, in sanctuaries of which no one knew the true destination. For ten thousand years, a hundred thousand years or more, the books of secrecy slept in an immense and reassuring sleep.
It was necessary for the happiness of humanity that no one could read them. This book, based on documents and discoveries, will solicit the revelation of a past that men no longer remember. We do not have the ambition to substitute for the history of the known four millennia another relation of the facts, but to reveal, in the form of a report, the essential of the inexplicable phenomena which were observed in the past.
