Bauval's idea is that the pyramid's are not burial chambers but tempels, built in the pattern of the stars. He presents plenty of proof for this and the only people to doubt him may be egyptologists. Unfortunately, he spends three quarters of the book trying to convince these experts, boring the average reader. In the last quarter of the book, he goes overboard into speculation, interesting maybe, but hastily put together. It may be better to try one of his later books, for further cristalized ideas. Still, the book leaves you in awe of this ancient civilization which developed a master plan to connect heaven and earth, 5000 years ago, when contracters could still be trusted.
