Terra Australis (Latin for South Land) was a hypothetical continent first posited in Antiquity and which appeared on maps between the 15th and 18th centuries. Although the landmass was drawn onto maps, Terra Australis was not based on any actual surveying of such a landmass but rather based on the hypothesis that continents in the Northern Hemisphere should be balanced by land in the south. This theory of balancing land has been documented as early as the 5th century on maps by Macrobius, who uses the term Australis on his maps.
