Not actually a book but a DVD (and CD) in which Tom Brooks suggests, in his Prehistoric Geometry in Britain, that, "...prehistoric man navigated his way across England using a crude version of 'sat nav' based on stone circle markers; they (prehistoric man) were able to travel between settlements with pinpoint accuracy thanks to a complex network of hilltop monuments. New research suggests that they were built on a connecting grid of isosceles triangles that 'point' to the next site. Many are 100 miles or more away, but GPS co-ordinates show all are accurate to within 100 metres. This provided a simple way for ancient Britons to navigate successfully from A to B without the need for maps."*
Dunno where to start . Does anybody actually accept any of this ? Brooks' research, "...based upon the true position of each unit relative to all others according to the Ordnance Survey National Grid, reveals that all are related geometrically by isosceles triangles (having two sides equal) and projected alignments of remarkable accuracy over great distances. Further, such isosceles triangulation was directed from and focused upon a single, central feature more than 5,000 years old - Silbury Hill on the Marlborough Downs in Wiltshire."**
