David Childress, popular author and star of the History Channel's show Ancient Aliens, brings us a stunning tale of archeological investigation on a megalithic scale. Childress looks into the enigma of obelisks and their purpose. Egyptologists tell us that obelisks are granite towers that symbolize a ray of the sun--a megalithic symbol of the Sun God Ra, later to be called Aton. Some obelisks weigh over 500 tons and are massive blocks of polished granite that would be extremely difficult to quarry and erect even with modern equipment. Why did ancient civilizations in Egypt, Ethiopia and elsewhere undertake the massive enterprise it would have been to erect a single obelisk, much less dozens of them? Were obelisks more than simple monuments? Were they energy towers that could receive or transmit energy? Childress takes us on an amazing journey through the history of the obelisk and its probable purpose as an energy tower. With discussions on Tesla's wireless power, and the use of obelisks as gigantic acupuncture needles for earth, Childress shows us what the ancients were trying to achieve with their mysterious obelisks.
