Hapgood analyzes this map in great detail but the one fact that makes it most noteworthy is the detailed depiction of western Antarctica centuries before anyone in modern times knew the continent existed. The Piri Reis map of 1513 is a fragment of a larger map of the world, based on source maps going back to ancient Alexandria and beyond.

Hapgood's "Maps of the Ancient Sea Kings" may be known mostly for publicizing the existence of what is commonly called the Piri Reis Map, but as the first word in the title suggests there are many ancient maps evidencing knowledge we once believed was discovered more recently.
