Although now somewhat outdated in certain aspects of interpretation, this book surely will remain as one the pillars for the study of ancient Egyptian religion, and, in fact, is one of the never-absent bibliographic references. I do not agree in toto with Frankfort's ideas about several subjects, but I must confess that it is one of the most interesting studies that I ever read about the matter. There are many thought-provoking ideas! Buy it, read it, learn from it. Both for the learned and the newcomer!
