The 1.17 x 1.59 metres Archipelagi Orientalis was one of two original and unrestored maps by Blaeu discovered in an Italian home.
Though only four copies of Blaeu's map are known to exist, the auctioned map was created even earlier than the copy held by Australia's National Library (1663).
On November 24, 1642, Dutch explorer Abel Tasman made the first recorded sighting of the Australian island state of Tasmania, 'New Atlas' reported.
As official cartographer of the Dutch East India Company, Bleau had complete access to the closely guarded intellectual properties of the most powerful company in the world.
Archipelagi Orientalis includes the first details of Tasman's sighting of Tasmania and the first map of the island's coastline.
