Does anyone know the name of the ancient ocean maps, found around the 1600’s?

They may have been hidden away by the Turkish Empire, showing the outlines of South America and Africa, composed prior to European navigation…
They may have been called Pir ______?

The Piri Reis map is a famous world map created by 16th century Ottoman Turkish admiral and cartographer Piri Reis. The surviving third of the map shows part of the western coasts of Europe and North Africa with reasonable accuracy, and the coast of Brazil is also easily recognizable. Various Atlantic islands including the Azores and Canary Islands are depicted, as is the mythical island of Antillia. The map is noteworthy for its apparent south-eastward extension of the American continent to depict a southern landmass that some controversially claim is evidence for early awareness of the existence of Antarctica.

Alternatively, it has been suggested that this is actually a record of the coast as far as Cape Horn, explored secretly by Portuguese navigators before 1507 (when it appeared on the Waldseemüller map) and bent south-eastward simply to fit on the parchment.
