One of the world's great mysteries lies just a few miles from the ancient Inca capital of Cusco Peru, at a place called Sacsayhuaman (Sexy-woman), where the remains of massive monoliths form what was once buildings and walls of a city center. In this special presentation - we'll look at the technology which may have been in place at the time of construction and note the purpose of such a complex,, with guest Jan Peter de Jong.Jan Peter de Jong is a Dutch researcher who lived in Peru for 13 years, and over the years made a number of fascinating discoveries in and around Cusco. In his investigations, he discovered the use of an unknown science and technology in the cutting or carving of granite rock. The stone blocks, (pictured) – appear to have been treated with some form of high heat which has shaped the stone in a manner that is completely baffling to our current understanding.De Jong is an expert at revealing what he terms the vitrification, or heating and molding of these stones, and has discovered structures throughout Peru which were treated with this process. Vitrification occurs as a result of exposing stone to extreme heat. The process has been found at several ancient sites around the world. In most examples the stone appears to have been subjected to extreme heats (over 1000°C), causing the rocks to melt and leaving a shiny almost polished texture to the surface, and smooth to the touch.For more information on Jan Peterde Jong work go to his website Ancient Mysteries Explained, http://www.ancient-mysteries-explained.com/- See more at: http://extraterrestrialcontact.com/2013/04/01/earth-ancients-jan-peter-de-jong/#sthash.gRVOs2T1.dpufBecome a supporter of this podcast: https://www.spreaker.com/podcast/earth-ancients--2790919/support.
