He is best known for his maps and charts collected in his Book of the Sea. He gained his fame as a map maker after a small part of his world map (prepared in 1513) was discovered in 1929, in Istanbul. The most interesting points of the map were its accuracy and a small continent that seemed to be linked to the southernmost tip of Southern America. Various people including Charles Hapgood and Erich von DänikenErich von Daniken (born April 14, 1935 in Zofingen, Switzerland) is a controversial Swiss author who is best known for his theories about extraterrestrial influence on human culture since prehistoric times, known as paleocontact and ancient astronaut theo considered this as a sign of the discovery of the continent of AntarcticaAntarctica (from Greek nu;ταρκτικ&sigmaf opposed to the arctic) is a continent surrounding the Earth's South Pole. It is the coldest place on earth and is almost entirely covered by ice. It is not to be confused with the many centuries before the traditionally accepted date, and even as a proof for the presence of extraterrestrial civilizations, which were supposed to have drawn the original map. However, most scientists do not agree that the Piri Reis map is any more accurate than might be expected based on contemporary geographical knowledge and guesswork.
The sources and references of the map have been noted in detail in Ottoman-Turkish on the map and he seems to have based the map on the works of PtolemyThis article is about the geographer and astronomer Ptolemy. For Alexander the Great's general, see Ptolemy I of Egypt. For others, see Ptolemy (disambiguation). Claudius Ptolemaeus (Greek: Klaudios Ptolemaios; A. circa 85 circa 165), known in English as, Portuguese maps, and Christopher ColumbusChristopher Columbus ( 1451 1— May 20, 1506) was an explorer and trader who crossed the Atlantic Ocean and reached the Americas in 1492 under the flag of Castilian Spain. He believed that the earth was a relatively small sphere, and argued that a ship cou. The small landmass depicted on the southernmost part of the map is considered to be an imaginary continent, which was assumed to counterbalance the continents of the northern hemisphere, since the time of ancient Greeks ( Terra AustralisTerra Australis (more completely Terra Australis Incognita, "(the) unknown southern land") was an imaginary continent, appearing on European maps from the fifteenth to the eighteenth century. It was first introduced by Ptolemy, a Greek cartographer from t). More likely though it is just the continuation of the South American coast which would have otherwise had to end abruptly half way down. There is also evidence that it is a later addition to the original map and is displayed awkwardly only so as to fit in. The real interesting point of the map is that it is reflects Columbus' ideas about the new lands to the west and probably is the best preserved copy of one of his earliest maps.
