Undeniable is that the Maps of the Ancient Sea Kings (by Charles Hapgood) prove that the ancients, even during the Ice Age, were navigating all over the globe to map such as Antarctica, showing its mountain ranges before the snow covered them, on the Piri Reis map with the eastern coast of South America also shown. The medieval Maps of the Ancient Sea Kings were obviously compilations of ancient source maps not fitted well together because those in medieval times were fully ignorant of the remote parts of the world, more proof that the ancients used a method for geometry unknown to those in medieval times, by the axial precession rate of the earth, 72 years/degree.
