Vinland map declared genuine


COPENHAGEN (Reuters) - The 15th century Vinland Map, the first known map to show part of America before explorer Christopher Columbus landed on the continent, is almost certainly genuine, a Danish expert said Friday...

"All the tests that we have done over the past five years -- on the materials and other aspects -- do not show any signs of forgery," Rene Larsen, rector of the School of Conservation under the Royal Danish Academy of Fine Arts, told Reuters...

The map shows both Greenland and a western Atlantic island "Vinilanda Insula," the Vinland of the Icelandic sagas, now linked by scholars to Newfoundland where Norsemen under Leif Eriksson settled around AD 1000...

He said claims the ink was too recent because it contained a substance called anatase titanium dioxide could be rejected because medieval maps have been found with the same substance, which probably came from sand used to dry wet ink.

American scholars have carbon dated the map to about 1440, about 50 years before Columbus "discovered" the New World in 1492. Scholars believe it was produced for a 1440 church council at Basel, Switzerland.

The Vinland Map is not a "Viking map" and does not alter the historical understanding of who first sailed to North America. But if it is genuine, it shows that the New World was known not only to Norsemen but also to other Europeans at least half a century before Columbus's voyage.

The lack of a provenance has caused much of the controversy. Where the map came from and how it came into the hands of the Swiss dealer after World War Two remain a mystery.
