The obelisk is Egyptian. It's in the shape of a crystal. A quartz crystal, when squeezed, gives off pizoelectricity. Also possibly gravity reduction. The Egyptians preserved knowledge from earlier civilizations that were destroyed during the ice ages. Atlantis and Mu were two of them. Crystal technology was partially preserved among that knowledge. Standing stones circled by rings of stone can be found throughout northern Europe that are made of granite, which is rich in quartz. They are a complete mystery to scientists and historians. The Freemasons sought out all the ancient knowledge during the 18th century and kept it in private collections, away from the public. Some of that knowledge was used to build the city of Washington in DC.
