Tom Brooks is a British author, draftsman and a proponent of Prehistoric geometry theories.

[1] Brooks was born in London and attended East Sheen Grammar School before returning to his family home in Devon where he attended Colyton Grammar School.

His career included time spent in the Royal Navy along with being a Marketing director and a draftsman.

In a survey of over 1500 ancient sites in Britain, Brooks claims that many were constructed by prehistoric man on a connecting grid of isosceles triangles spiraling outwards from Silbury Hill (pictured) with each triangle pointing to the next site.

Archaeologists have made the criticism that many such patterns can be easily found as Britain is so rich in ancient sites of different types from different periods.
