This week Jason, for the tenth time, takes command of the show to educate us all about the highly controversial document known as the Piri Reis map. This piece of cartography, which was produced in the 16th century, has been purported to show the coastline of Antartica as it would have appear without its ice cap, millions of years ago. This has lead to a number of speculations, regarding advanced civilizations surviving apocalypse level events and global ice ages, as well as a transmission of knowledge which goes back thousand of years. We hope you'll enjoy as we dive into the mystery that is the Piri Reis map!
