Age of Exploration Maps and the Curious Polygonal Building Style found Around the World and Underwater. The Piri Reis map, drawn in 1513, accurately depicts the African and South American coast and depicts a string of islands off the Antarctica coast, a continent not even officially discovered until 1821. How could early maps depict islands that are deep under the ice and only now being discovered? Considering these islands were only exposed before the last Ice Age, the Piri Reis Map is likely drawn from a source map between 12,000 and 10,000 years old, making the case for it being Prediluvian. The appended notes say “the map of the western lands drawn by Columbus” and derived from source maps of the Library of Alexandria. One of the greatest mysteries of the ancient world is how the massive 70-ton megalithic blocks of pre-Inca South America were moved and expertly locked into place. Examples of a similar polygonal stone constructions are found worldwide. Could it be the lost art of using cold plasma to shape the megalithic stones? Or the use of the forgotten science of auditive levitation to move the massive blocks into position? What do we make of the myriad of underwater megalithic sites being found that could have only been constructed during the last Ice Age?
