Joseph Davidovits explains the intriguing theory that made him famous. He shows how the Pyramids were built by using re-agglomerated stone (a natural limestone treated like a concrete), and not with huge carved blocks, hauled on fragile ramps. Archaeology bears him out, as well as hieroglyphic texts, scientific analysis, religious and historical facts. The author sweeps aside the conventional image which cripples Egyptology and delivers a captivating and surprising view of this civilisation; the first complete presentation on how the pyramids were built. The revelations are sensational, especially when he explains why the pharaohs stopped building great pyramids because of an over-exploitation of raw materials and a likely environmental disaster. He charts the rise of this technology, its apogee at Giza, and the decline. Everything is logical, everything fits into place.
