The construction of the Great Pyramid |

How
Were the Stone Blocks CUT?
Various
lifting devices and levers have been proposed by modern engineers. |
| The
known tools would only barely cut through limestone and would be useless
with granite. No archaeological examples of iron tools are found in early
dynasticEgypt.
The best steels today have a hardness of only 5.5 and thus are inefficient
for cutting granite. It was thought that the pyramid blocks had been cut
with long saw blades studded with diamonds or corundum. The cutting of millions
of blocks would require millionsof rare and expensive diamonds and corundum.
We
have no idea how the blocks were actually quarried. |

The
most extraordinary problem, that of the fashioning and placement of the
highly polished limestone
casing stones that covered the entire pyramid. The finished pyramid contained approximately 115,000 of these stones, each weighing ten tons or more. These stones were dressed on all six of their sides, not just the side exposed to the visible surface, to tolerances of .01 inch. They are set together so closely that a thin razor bladecannot be inserted between the stones. Merely to place such stones in exact contact would be careful work, but to do so with cement in the joint seems almost impossible; it is to be compared to the finest opticians' work on the scale of acres. Herodotus,
visiting in the fifth century BC, reported that inscriptions of strange
characters were to be found on the pyramid's casing stones. In AD 1179
the Arab historian Abd el Latif recorded that these inscriptions were
so numerous that they could have filled "more than ten thousand written
pages." There are water marks halfway up the sides of the pyramid, or about 400 feet above the present level of the Nile River. Further, when the Great Pyramid was first opened, incrustations of salt an inch thick were found inside. While much of this salt is known to be natural exudation from the stones of the pyramid, chemical analysis has shown that some of the salt has a mineral content consistent with salt from the sea. These salt incrustations, found at a height corresponding to the water level marks left on the exterior, are further evidence that at some time in the distant past the pyramid was submerged halfway up its height. |
