"Maps of the fifteenth to eighteenth centuries are a favourite source of information for fringe writers, who use them to make a wide variety of claims. To Erich von Däniken, for instance, they are evidence for a survey of the Earth from space, carried out by extraterrestrials, while for Graham Hancock, they are evidence for an ancient sea-faring civilisation, lost beneath the sea after the melting of glacial ice at the end of the Pleistocene." - Mark H from Bookmarklet
Good debunking of the claims of inexplicable ancient knowledge which highlights how cartographers were far more diligent than those who've come after them with preconceptions they then try to prove using the incredible power of overlooking things that run counter to that viewpoint. Many of the claims follow on from the work of a geography teacher who overheard a radio discussion between a US navy engineer and two priests; the engineer, far from being something of an expert, was the kind of person who believed the Vikings started an Iron Age in North America without evidence to support it. Some careful ignoring of all the writing on the maps that indicate exactly what land masses were later and legends are born. - Mark H
