This book is essential for any traveller to Egypt with a mind that is even slightly ajar, let alone open.
West gives an alternative account of the meaning of the monuments and antiquities to be seen in Egypt, more esoteric (though certainly not more difficult to understand) than that which is usually presented in guide books. He points out the details which brought him to the conclusion that the Giza Sphinx is in fact closer to 13,000 years old than the 4,500 years old that has been traditionally believed, and has a different viewpoint to the orthodox school in many cases. He presents both sides of the argument, and gives the information necessary to make up one's own mind based on observation of what is actually there to be seen.
On my first visit to Egypt, my companions and I felt rather sorry for tourists in groups with official guides, because they seemed to be missing out on at least half of the story, and in many cases the whole point.
I was particularly impressed with West's analysis of the architecture of the Temple of Luxor, based on the work of Schwaller de Lubicz, and once it was pointed out how the whole building maps onto a plan of the human skeleton, I found it very difficult to refute.
Whilst I did not always agree with his conclusions on every occasion, it cannot be disputed that West has raised thoroughly pertinent questions which conventional Egyptology has either glibly brushed under the carpet or failed to address at all.
