I certainly haven't read the whole book, but two things struck me. First, the author claims to see all sorts of figures (human, animal, conceptual) in the surface of stones from numerous monuments which he 'illustrates' with photographs, but for the life of me they seem pretty tenuous, highly subjective, and lighting-dependent. Second, he claims to have solved definitively a number of great mysteries relating to these monuments, etc., but I saw no sign of this. Am I missing something? The book generally has the appearance of what used to be called 'vanity publishing': In other words, self-published.
