A reet riveting read.

The author concludes that ancient humans (pre stoneage, pre Noah flood etc) had access to forgotten technology to build stuff like the pyramids. Too many researchers into this kind of stuff are too quick to suggest that an alien race or alien technology did it all, but this author says that we should give humans more credit.
Perhaps the Wests interest in the Middle East is not just for oil, but to look for clues to a far more powerful energy that has been forgotten or lost over the millenia. It was written in 1975 but still describes mysteries that have yet to be properly explained in relation to ancient monuments and artifacts.
