The Piri Reis Map has been confuddling researchers and experts for years. How could someone make such a detailed map in 1513? Any why does it show Antartica on it, when it wasn't discovered until 300 years later? Could the map maker, Piri Reis himself, have had help from mysterious sources? Athena and Tiernan plot the best route through all the evidence so that you, our Chief Detectives can decide the truth.
