The Orion Mystery, published in 1994, introduced the world to a highly original, and now internationally famous, star-correlation theory about the Giza Pyramids in Egypt. It sent a huge shock-wave of controversy throughout the scientific community, the effects of which are still felt today. The Egypt Code develops this pyramid-stars correlation, challenging the long held assumption by many Egyptologists that the pyramids were tombs principally meant to house the bodies of dead kings. In addition to this theory, Robert Bauval also reveals an amazing 'Grand Unified Plan', which involves the wonderful temple of Upper Egypt. The Egypt Code is unlike any other book before it and covers the whole of Egypt's ancient civilisation in a manner never before attempted. Much has been written as to 'how' the Egyptians might have aligned their monuments with such high precision, but the question that has always remained unanswered is 'why?'- why did the ancients put so much emphasis on astronomical alignments? And what could be the function, practical or symbolic, behind these mysterious alignments?
