it is a world map compiled at 1513 by an admiral of the ottoman empire (piri reis).
only the one third of the map survives today.
the map discovered at 1929 by a german theologian.
the "mystery about this map is that it presisely represents the coasts of antartica.
but there is a problem there
antarctica was not known at that times (1513).
and the most bizzare is that the map represends antarctica the way it was before the ice age!!!
that lead many scholars and researchers to the conclusion that this map had been made by an advanced civilization existed before the ice ages!
some even more enthusiastic speaking of an ancient map that was made even in atlantis...some others saying atlantis is under the ices of today's antarctica...
anyways antarctica is sure a magical place full of mysteries yet to be discovered.....
Excellent
