d feathers are wrapped around their heads and waists.�Of the Australians, it reports “The skin of the aborigine is also black. All of them are naked and wearing bone articles around their waists.� But this remarkable precision, rather than the errors, is what critics of the Menzies theory are likely to use to question the authenticity of the 1418 map. Mr Menzies and his followers are naturally extremely keen to establish that the 1763 copy is not a forgery and that it faithfully represents the 1418 original. This would lend weighty support to their thesis that China had indeed discovered America by (if not actually in) 1421. Mass spectrography analysis to date the copied map is under way at Waikato University in New Zealand, and the results will be announced in February. But even if affirmative, this analysis is of limited importance since it can do no more than date the copyist s paper and inks. Five academic experts on ancient charts note that the 1418 map puts together information that was available piecemeal in China from earlier nautical maps, going back to the 13th century and Kublai Khan, who was no mean explorer himself. They believe it is authentic. The map makes good estimates of the latitude and longitude of much of the world, and recognises that the earth is round. “The Chinese were almost certainly aware of longitude before Zheng He set sail,�says Robert Cribbs of California State University. They certainly assumed the world was round. “The format of the map is totally consistent with the level of knowledge that we should expect of royal Chinese geographers following the voyages of Zheng He,�says Mr Thompson. Moreover, some of the errors in the 1418 map soon turned up in European maps, the most striking being California drawn as an island. The Portuguese are aware of a world map drawn before 1420 by a cartographer named Albertin di Virga, which showed Africa and the Americas. Since no Portuguese seame fuel dispenser n had yet discovered those places, the most obvious so fuel dispenser fuel dispenser
