This book is about lifting precision, not stones. Global headlines were made when Norwegian architect and researcher Ole Jørgen Bryn published his first article on the ancient Egyptian pyramids in 2010. Unlike numerous of existing theories concerning the building of these immense stone structures -- often put forward by historians, Egyptologists, and archaeologists -- Bryn's approach is as different and original as it is simple. In this book, Ole J. Bryn suggests that the Egyptians invented the architectural and engineering professions, and he finds evidence in the apex point; an invisible, theoretical point 146.6 metres above the ground level of Khufu's Great Pyramid at Giza. How the pyramids were built derives directly from how they were planned. However, the planning phase has not yet been explored in the research literature with the same vigour as the building phase. This book aims to balance this incongruity by examining thoroughly, in detailed project drawings, the 30 fi rst Egyptian pyramids from the 3rd, 4th, and 5th dynasties. The author's theories about the planning phase of the pyramids are enhanced by his unique project drawings of the pyramids, and supported by photographs taken by fellow architect Håvard Houen.
