What new evidence points to a prediluvian civilization in Egypt that knew how to harness the properties of stone to generate power? Saqqara, 22 miles south of Giza, holds two of the greatest mysteries of the ancient world: the Djoser pyramid and the Serapeum, which may be the source of power for Giza. These monuments are the enduring legacy of Imhotep, a student of Thoth and one of Egypt’s greatest polymaths. This subterranean complex is so vast and unexplored that the new findings are merely a fragment of the enigma surrounding Saqqara. Will the secrets unearthed finally reveal who built the Serapeum and why?
