Stonehenge: Solving the Neolithic Universe
This fully illustrated e-book, by a Fellow of two engineering institutions, puts forward a detailed and fully developed alternative interpretation for Stonehenge based on recent research into renewable energy: It shows how its plan layout is the same as an idealized geocentric (fixed world) description of the Universe; its inner stone monument is shown to be capable of creating a spectacular visual description of a the sun's movement around a fixed world.
Part 2 shows examples of where that early knowledge of the Universe could have been obtained. It also shows that, in all the locations needed, the monuments of that period appear to fit that which would be required.
Part 3 is about how the monuments would be perceived: It shows how mythological and Arthurian references all appear to fit this explanation of Stonehenge and other monuments. This offers an alternative explanation for the Grail and the Four Treasures of.the Tuatha Dé Danann.
Part 4 looks at the most recent evidence published in 2012 and part 5 summarizes the possibilities.
