Innu, known by the Greeks as Heliopolis - which was regarded throughout the dynastic period as the source and centre of high wisdom handed down to mortal men from the fabled First Time of the gods. It was at Heliopolis that the Pyramid Texts were collated, and it was the Heliopolitan priesthood, or rather Heliopolitan cult - that had custody of the monuments of the Giza necropolis. 35 Hancock's hypothesis, reached after more than 500 pages of discussion and a wealth of detailed references was that certain monuments might contain valuable information, if not the prevailing wisdom of the time, deliberately incorporated or buried in their structures. As a corollorary, the monuments might also provide the much needed reason for their actual construction in terms of the event itself. But having made this suggestion it is necessary to emphasize that it is not necessarily beneficial to defer the technical and mathematical knowledge inherent in the construction of such monuments to extra-terrestrial help and/or lost civilizations, even though such possibilities cannot be entirely discounted. On the other hand, if we consider that the monuments were largely the product of unthinkable toil, extremes of hardship and the very best that the minds of those times could muster, then we most assuredly need to determine exactly what it was that motivated them, how well the matter was understood, and how much of it they managed to pass down to us. Thus we arrive back at the original question only to add three more.
