Greek and Roman philosophers had predicted the existence of a great southern landmass some 2000 years ago. As the earth was a sphere, they believed there must be a huge continent to the south to counterbalance the continents in the north.
Originally postulated by Aristotle, Ptolemy then expanded this notion of Terra Australis Incognita - the unknown southern land.
It would take until the 18th century before this mysterious continent was finally located, charted and later named Australia. Explore the State Library's incredible maps, journals, drawings and books to understand how the pieces of our continent were gradually put together.
