The cartographic depictions of the southern continent in the 16th and early 17th centuries, as might be expected for a concept based on such abundant conjecture and minimal data, varied wildly from map to map; in general, the continent shrank as potential locations were reinterpreted. At its largest, the continent included Tierra del Fuego, separated from South America by a small strait; New Guinea; and what would come to be called Australia. In Ortelius's atlas "Theatrum Orbis Terrarum", published in 1570, Terra Australis extends north of the Tropic of Capricorn in the Pacific Ocean.
