RESTORING ONE OF THE WORLD’S RAREST MAPS

Reading time: 4 minutes

In 1663, Europeans called Australia ‘New Holland’, New Zealand was considered one land mass and Tasmania had only been sighted by Abel Tasman – it would be another hundred years before Europeans would set foot there.

The powerful Dutch East India company, which traded in and between Asia and Europe for two centuries, held and protected this knowledge; it was commercially sensitive and competition was fierce.

But while these traders dismissed Australia’s potential as a commercial partner, they were responsible for one of its first maps: the Archipelagus Orientalis, sive Asiaticus (Eastern and Asian archipelago), produced by their master cartographer Joan Blaeu.

By Libby Melzer.

The first large-scale map of the land that would come to be known as Australia, it is one of the rarest in the world. Four copies are known to exist, and the National Library of Australia acquired one of them in 2013.

“The map was found in a storage unit in Sweden in 2010,” says Libby Melzer, Senior Paper Conservator from the University of Melbourne, who was part of the Grimwade Centre for Cultural Material Conservation team that restored it.

“It was in very poor condition because it was designed as a wall map,” she explains. “Exposure to air, people touching it and the varnish used on top all caused considerable degradation.”

In the past, Blaeu maps were considered very prestigious and were hung in important homes and buildings.

“This particular map was part of a series of maps of the world,” says Ms Melzer. “Most cartographers at the time produced five maps in world series, but Blaeu was an important cartographer and his maps more prestigious and comprehensive, so he did seven. Hence why Australia is featured at all.”

The map shows the west coast and north of Australia in good detail, but much of the south coast and all of the east coast are largely absent – these areas would not be mapped until Captain Cook’s arrival over one hundred years later.

And it only shows the southern coast of Tasmania.

“Australia had no spice, so many of the discoveries of Australian land were incidental encounters along their way to the spice islands,” explains Ms Melzer.

“By contrast, the coastline through the trade routes into Indonesia is very well detailed – the Dutch were great cartographers and they knew that area well.”

It took over one thousand hours for the 11 person team at the Grimwade Centre to painstakingly restore the 354-year-old map.

“Normally we’d only dedicate one or two people to a conservation project, but this was a very special object, and it was significantly more difficult to conserve than most of our projects.

“The surface was very fragile and there were a lot of complications along the way.

“We thought we were just removing varnish, but we discovered a dirty layer underneath which meant we had four passes at each square on the gridded map – of which there were around 300.”

And the team also found some delightful surprises.

“There are lots of ship details on the map, and as we removed the varnish we discovered they bore either a Dutch or a Spanish flag. They are a key to indicate the owners of that territory,” says Ms Melzer.

“We also discovered the whale in the top left corner has two spouts. Perhaps they didn’t quite know what whales were when they first sighted them.”

The map has since returned to Canberra, where it forms part of the National Library of Australia’s new Mapping our World: Terra Incognita to Australia exhibition.
