The Great Pyramid by Martin Gray
The Great Pyramid is the most substantial ancient structure in the world - and the most mysterious. According to prevailing archaeological theory - and there is absolutely no evidence to confirm this idea - the three pyramids on the Giza plateau are funerary structures of three kings of the fourth dynasty (2575 to 2465 BC).
The Great Pyramid, attributed to Khufu (Cheops) is on the right of the photograph, the pyramid attributed to Khafra (Chephren) next to it, and that of Menkaura (Mycerinus) the smallest of the three.
The Great Pyramid was originally 481 feet, five inches tall (146.7 meters) and measured 755 feet (230 meters) along its sides. Covering an area of 13 acres, or 53,000 square meters, it is large enough to contain the European cathedrals of Florence, Milan, St. Peters, Westminster Abbey and St. Paul's.
Constructed from approximately 2.5 million limestone blocks weighing on average 2.6 tons each, its total mass is more than 6.3 million tons (representing more building material than is to be found in all the churches and cathedrals built in England since the time of Christ).
The Great Pyramid was originally encased in highly polished, smooth white limestone and capped, according to legend, by a perfect pyramid of black stone, probably onyx. Covering an area of 22 acres the white limestone casing was removed by an Arab sultan in AD 1356 in order to build mosques and fortresses in nearby Cairo.
Herodotus, the great Greek geographer, visited in the fifth century BC. Strabo, a Greco / Roman historian, came in the first century AD. Abdullah Al Mamun, son of the Caliph of Baghdad, forced the first historically recorded entrance in AD 820, and Napoleon was spellbound when he beheld the fantastic structure in 1798.
According to our present knowledge the Great Pyramid is mostly solid mass, its only known interior spaces being the Descending passage (the original entrance), the Ascending passage, the Grand Gallery, a mysterious grotto, an equally mysterious subterranean chamber, and the two main chambers. These two chambers, called the King's Chamber and the Queen's Chamber, have unfortunately retained the misleading names given to them by early Arab visitors to the pyramid.
It is an Arab custom to bury men in tombs with a flat roof and women in rooms with a gabled roof; therefore, in the Great Pyramid, the flat-roofed granite chamber became the King's Chamber, while the gabled, limestone chamber below became the Queen's.
Even those archaeologists who still stubbornly subscribe to the tomb theory of the pyramid do not believe that a queen or anyone else was ever buried in the limestone chamber. The King's Chamber is 10.46 meters east to west by 5.23 meters north to south by 5.81 meters high (a series of measurements that precisely expresses the mathematical proportion known as the Golden Mean, or Phi).
It is built of enormous blocks of solid red granite (weighing as much as 50 tons) that were transported by a still-unknown means from the quarries of Aswan 600 miles to the south. Within the chamber, in the western end, sits a large, lidless coffer (7.5 feet by 3.25 feet, with sides averaging 6.5 inches thick) of dark black granite estimated to weigh more than three tons.
When the Arab Abdullah Al Mamoun finally forced his entry into the chamber in AD 820 - the first entry since the chamber was sealed in some long ago time - he found the coffer entirely empty. Egyptologists assume that this was the final resting place of Khufu, yet not the slightest evidence suggests that a corpse had ever been in this coffer or chamber. Nor have any embalming materials, any fragments of any article, or any clues whatsoever been found in the chamber or anywhere else in the entire pyramid that in any way indicates that Khufu (or anyone else) was ever buried there..............
If interested in the mathematical relationships of the various elements read The Secrets of the Great Pyramid by Peter Tompkins. He reviews the various theories in detail (except the Orion's belt layout plan) and the use of pi and psi. He also gives a review of the ancient measurement systems in detail
Even those archaeologists who still stubbornly subscribe to the tomb theory of the pyramid...That would be a list of every actual Egyptologist. Not just most, every single one. I'm not sure of the number of people who stubbornly cling to the idea that the pyramids weren't constructed as pharaonic tombs.
...do not believe that a queen or anyone else was ever buried in the limestone chamber.The smaller, lower chamber probably held grave goods, and canopic jars. It, along with the burial chamber, were probably robbed in antiquity. During construction, there was a serious structural problem of some kind. Houdin et al attribute this to a settling of one side of the pyramid due to the immense weight of the structure. The corbels at the top of the Grand Gallery were found (by Petrie I think) to be holding on by less than an inch on one end, due to the shift (whatever its cause; used to be attributed to an earthquate). The pyramid was nearing completion -- the top half of the pyramid contains, hmm, about 1/9th of the mass, uh, I'd better get someone else to look at that -- and the chief architect had an inspection shaft dug from the top of the Grand Gallery to the first of the upper relieving chambers. In modern times the other relieving chambers were tunnelled into from the lowest one.
