This book challenges alot of modern thought on history, especially the ancient egyptians. Drunvelo makes some very interesting observations about the ancients that I have not come across before. He is very into his sacred geometry which makes this book a bit male and left-brained for me at times. But he knows his stuff and if you hang on in there, it`s facinating! He is a combination of mathematician, historian and out-there-spiritual-guy which gives his writing depth and credibility. There are many mysterious codes imbeded in the civilizations of the past and Drunvelo strings it all together and makes it look obvious! He chucks in conversations with angels as though we all have those to pass the time! Even Thoth crops up. (Am I alone in noting that Thoth seems to have had a hand in other people`s lives too? That guy just pops up all through the millenia-in any book he fancies!) Read and enjoy!
