Christopher Dunn is a master craftsman and engineer with thirty-five years of experience. In the last twenty years, he has published a dozen magazine articles on his theories about ancient technology, including the much quoted Advanced Machining in Ancient Egypt in Analog.
Chris Dunn ranks among the top researchers on this subject. His book is extremely well-researched and presented and, although very controversial in content and conclusions, will no doubt become a landmark and classic in the field of pyramid studies. --Robert G. Bauval, coauthor of The Orion Mystery
