Piri Reis Map
A surviving fragment of a 1513 Ottoman world map, claimed by the fringe to depict ice-free Antarctica — a reading rejected by the map's leading scholar.
The Piri Reis map is a genuine and historically valuable artifact: a fragment of a world map drawn in 1513 by the Ottoman admiral and cartographer Piri Reis, rediscovered in 1929 in the Topkapı Palace, Istanbul. Its own marginal notes state that it was compiled from about twenty source charts, including Portuguese and Arab maps and a map said to have been used by Columbus. It accurately shows the Atlantic and the coasts of West Africa, Iberia, and parts of South America for its date.
The controversy centers on a southern landmass that bends eastward at the bottom of the sheet. Charles Hapgood, in Maps of the Ancient Sea Kings (1966), argued this was Antarctica drawn before its coasts were buried in ice — implying a lost advanced civilization mapped the world in the Ice Age. The idea was amplified by Erich von Däniken, Graham Hancock, and on Ancient Aliens, where it became a cornerstone of the ancient-astronaut hypothesis.
The scholarly verdict is firmly against the ice-free-Antarctica reading. Gregory McIntosh, the modern authority on the map, demonstrates that the ‘Antarctica’ is simply the coast of South America bent eastward to fit the available parchment — a common cartographic distortion — and that nothing on the map depicts lands unknown in 1513. The argument also fails on physics: Antarctica’s ice sheet is millions of years old, so there was no recent ice-free coast to chart. The map is a remarkable work of Renaissance cartography assembled from known sources.
