I had a good time with "Mysteries of the Egyptian Pyramids" by the same author, and this book delivers the same resources. There's a short history of the archaeology of Pyramids from the professional point of view, some high quality 19th century etchings, and then a good deal of loose reasoning about the purpose and functions of the structures. I believe this book antedates the discovery that many Maya pyramids are accretions, a set of pyramids built one over the other, gradually growing in size. So it's entertaining, and in the main untrustworthy, unless one is looking for RPG background material. ( )
