People have been speculating for centuries about how the ancient Egyptians built the Great Pyramids. Few people have paid attention to Herodotus and his writings about Egypt's intricate canal system, but historian James V. Barr believes these played a critical role in pyramid construction. Relying on years of research, he presents the lock and canal system of construction. Barr also examines other theories of pyramid construction such as the levitation theory and the ramp theory. He explains why explanations of pyramid construction that do not focus on the canal system are wrong and why the canal and lock system makes the most sense. Barr hopes to show Egypt both as it once was and as it is today, sharing entirely new photographs, drawings, and maps. This is concise, informative primer for anyone who wants to learn more about the methods employed in pyramid construction.
