This book contains introductory material in the first half, and excerpts from The Temple of Man in the second half, making it the perfect introduction to this author. Schwaller de Lubicz proves countless points about ancient Egypt's level of philosophical, cultural and mathematical sophistication that eliminate conventional ideas about history as likely or even possible. It's too bad this work doesn't reach the audience it deserves. Less compelling is the fact that the bulk of his work, including this book, is nothing but his own medieval, alchemical philosophy projected onto the Egyptians. His ideas are interesting on an intellectual level, but not to be taken literally, and they won't exactly lead you to the "philospher's stone". Unlike de Lubicz's measurements or his observation of water erosion on the Sphinx, which we can reproduce, his interpretations of the meaning of the heiroglyphs are entirely subjective and spring from his own prejudices. So there is much gold here, but you must know how to separate it from the fool's gold.
