Terra Australis

Terra Australis (also: Terra Australis Incognita, Latin for "the unknown land of the South") was an imaginary continent, appearing on European maps from the fifteenth to the eighteenth century. It was first introduced by Aristotle. Aristotle's ideas were later expanded by Ptolemy, a Greek cartographer from the first century AD, who believed that the Indian Ocean was enclosed on the south by land. When, during the Renaissance, Ptolemy became the main source of information for European cartographers, the land started to appear on their maps. Although voyages of discovery sometimes did reduce the area where the continent could be found, cartographers kept drawing it on their maps and scientists argued for its existence with such arguments as that there should be a large landmass in the south as a counterweight against the known landmasses in the Northern Hemisphere. Usually the land was shown as a continent around the South Pole, but much larger than the actual Antarctica, spreading far north in particular in the Pacific Ocean area. New Zealand, discovered by Abel Tasman in 1642, was by some regarded as a part of the continent as well as Africa and Australia.
