The Message of the Sphinx: A Quest for the Hidden Legacy of Mankind - Graham Hancock, Robert Bauval An entertaining book, although I don't think it's for the intent that the authors meant. I found it amusing simply due to the lack of a founded argument. There are distinct reasons the erosion on the Sphinx is there, and it isn't water. The inclusion of astrology in the authors' argument was absolutely unexpected not to mention ridiculous. There may have been restoration efforts on it, but we honestly have any documented evidence to prove that. Also, the implications of aliens was just downright laughable.If you are looking for a good discourse on the Sphinx based on archaeological evidence, this is not the book for you. However, if you are looking at reading a book on pseudoscience for giggles, you will enjoy it.
