Terra Australis meaning Southern Land was an early concept of the ancient Greeks, who imagined a large landmass in the southern hemisphere. Cartographers from the 15th century onwards included this hypothetical land on their maps of the world. When Australia and Antarctica were eventually discovered by European explorers it was seen as justification for the earlier.speculation.
Riaan Booysen, a South African researcher contends that these early maps reflected geographical realities, namely Australia and Antarctica,but goes further and locates Plato’s Atlantis close to Australia. He bases much of his theory on his interpretation of Johann Schöner’s 1515 globe, which he discusses on his extensively illustrated website(a).
