One of the first European maps to depict Australia, by the 17th-century Dutch cartographer Johannes Blaeu, is to go on display at the National Library in Canberra after being extensively restored.

The map, which measures 118 by 152 cm, was found in a Swedish book dealer’s storeroom in 2010 and acquired by the library for €400,000 at auction.

It is one of the few surviving copies of Blaeu’s map, which showed a recognisable but incomplete outline of the Australian mainland, but with Papua New Guinea attached to the continent and the eastern coastline missing.

Published in 1662 with the titled ‘Archipelagus Orientalis’ (the eastern archipelago), it is the first map to show Tasmania – then called Anthoni van Diemens Landt – and also gives a detailed rendition of modern-day Indonesia.

The document needed years of painstaking restoration before it could go on public display, having been recovered in poor condition with rotted paper and faded ink.
