Stone Age satnav: Did ancient man use 5,000-year-old travel chart to navigate across Britain<\/a><\/p>\n

When did a chart become satellite navigation?<\/p>\n

It’s considered to be one of the more recent innovations to help the hapless traveller.
\nBut the satnav system may not be as modern as we think.<\/p><\/blockquote>\n

On the contrary. I think the satnav system is precisely as old as we think.<\/p>\n

He analysed 1,500 prehistoric sites in England and Wales and was able to connect all of them to at least two other sites using isosceles triangles – these are triangles with two sides the same length.<\/p>\n

This, he says, is proof that the landmarks were deliberately created as navigational aides. Many were built within sight of each other and provided a simple way to get from A to B.<\/p><\/blockquote>\n

Or, settlements were quasi-equally spaced, as the terrain allowed, because most people making a new settlement probably wouldn’t choose a site too close to an existing settlement, for fear of conflict.<\/p>\n

Mr Brooks added: ‘The sides of some of the triangles are over 100 miles across, yet the distances are accurate to within 100 metres. You cannot do that by chance.<\/p><\/blockquote>\n

I wouldn’t be at all surprised if you could. Given the kind of packing restrictions present, I’d bet a semi-random distribution of sites would yield many such triangles.<\/p>\n
