Robert Temple Explains The Challenge Posed To Egyptology By A New Dating Technique
Our ability to truly understand ancient peoples and cultures has been handicapped until now by the lack of any method to date ancient buildings directly. Archaeologists have been forced to infer the date of a structure by dating organic remains or pottery found in or around it. Thus, dates for the buildings themselves have never been certain, because they are based on indirect evidence. Now things have changed.
My colleague Professor Ioannis Liritzis, of the University of the Aegean at Rhodes, a former nuclear physicist who turned his expertise to the needs of archaeology, has devised the Liritzis Dating Technique, the technical name of which is optical thermoluminescence. By his technique he can date the time of construction of a stone building by taking a small sample at the join of two blocks of stone. His technique yields a date for when that stone was last exposed to sunlight, or in other words, when the stones were placed together to build the structure.
Professor Liritzis has now dated a sample of the exterior granite casing stones of the Pyramid of Mycerinus (Menkaure) at Giza to between 3590 BC and 2640 BC. With optical thermoluminesence, one often gets these wide spreads. But let us just see what this means for Egyptian chronology.
The most recent possible date for the pyramid is thus one year before the foundation of the Egyptian Fourth Dynasty by its first king, Sneferu (using currently accepted chronologies). But according to conventional notions, the Giza pyramids were all built by Fourth Dynasty kings, and the last of the three to be built was the small one called the Pyramid of Mycerinus. Cheops (Khufu) was said to have built the Great Pyramid, often called the Pyramid of Cheops, and Chephren (Khafre) was said to have built the second largest (which still has some casing stones on top), called the Pyramid of Chephren. Now we see that none of this can be true, unless the chronologies are altered.
A median date for the Pyramid of Mycerinus is 3090 BC, which is 58 years earlier than the conventional date for the founding of the First Dynasty. Whereas the earliest date is so far back in Pre-Dynastic times that we have no idea of what may or may not have been happening then at Giza, or whether anyone was there at all.
In other words, our sampling indicated that the pyramids are far too old to have been built by Cheops, Chephren and Mycerinus, if one keeps them at their conventional dates. We must conclude, then, that instead of building them these pharaohs merely appropriated them.
Naturally this is all very upsetting to people who like to think conventionally. Whenever puzzling new discoveries are made, what happens next always boils down to human psychology. Acceptance or rejection of new evidence often depends not on some austere ‘quest for the truth’, but instead upon the all too human question of psychological attitude. Scholars are notoriously afflicted by the unspoken preoccupations of their kind: Will I get that professorship if I dare to take notice of this new finding? Could I bear the shame and humiliation of having to admit that I was wrong?
It is worth noting that these early dates that we found accord with the results of two Carbon-14 analyses made of organic material found within the mortar used between the blocks of the Giza pyramids; prominent in this study was Dr. Mark Lehner, who has been studying the Giza Plateau since 1979. The first was published in 1993: they reported that all sites were older by an average of 374 years; the second, published in 2001, simply coyly reiterated that the match between the accepted dates and the Carbon-14 dates was only approximate. The conclusion that the structures were older than thought was assiduously back-pedalled!
The Osiris Shaft
We took two dates from a deep shaft beneath the causeway that leads up to the Pyramid of Chephren. This shaft, which drops 114 beneath the surface, is called the Osiris Shaft because at the bottom of it, there is a replica of the mythical ‘Tomb of Osiris’, a stone sarcophagus set in the middle of a small island surrounded by an artificial canal. Before they were destroyed, apparently by Muslim fanatics at some time subsequent to 1944 (when we know they still existed), the island had four columns at each corner. The site has been so savagely vandalized that that may be the reason why no photos are ever circulated of it, and those which I have taken are essentially the only ones available We have dated the sarcophagus on the Osiris Island and also a sarcophagus on the burial level above it, as the shaft contains three horizontal levels. From our dating results, we can now demonstrate that the third level with the ‘Tomb of Osiris’ was evidently a later extension of the shaft made in the period between the Fifth Dynasty and the end of the Middle Kingdom, when the Osiris religion was at its peak. But the really interesting results came from Level Two. We dated a sample from one of the giant stone sarcophagi in that level and the result was 3350 – 2250 BC. The upper limit for this date is also, like the pyramid date, way back in Pre-Dynastic times. And a median date is 2800 BC, which is early in the Second Dynasty. This particular sarcophagus was also determined by X-ray diffraction analysis to have been made from the mineral dacite, which is otherwise unknown in the entire history of Egypt, having, as far as we know, never been used either before or since for any object, however small. Deposits of dacite in Egypt are uncommon and none have been reported with veins large enough to make a sarcophagus. What are we to make of all this? The Giza pyramids are surrounded by tombs of the family and courtiers of the Fourth Dynasty kings, starting with Cheops. So clearly Cheops, Chephren and Mycerinus were fixated on the pyramids that bear their names. But it appears that they ‘usurped’ them rather than built them. So who then really did build them? I have spent a great deal of time attempting to answer this perplexing question. But one thing is sure, it was someone much earlier than we thought.
not happy using freemasonary today as a source but it states everything i was about to write about professor Ioannis Liritzis and the new dating technology , and the new dates for the alleged last pyramid in the 4th dynasty , the pyramid of Mycerinus.
