We wanted to use science to test the accepted historical dates of several Old Kingdom monuments. Koch Pyramids Radiocarbon Project now has us thinking about forest ecologies, site formation processes, and ancient industry and its environmental impact--in sum, the society and economy that left the Egyptian pyramids as hallmarks for all later humanity. This was determined through the awareness that the circumference of the world had been over-estimated unless trigonometry was applied , and that this figure was close to that predicted by Eratoshenes suggesting that the calculations had been based on an early copy of these maps, which unknowingly included spherical trigonometry. The tombs' proximity to the pyramids and the manner of burial supports the theory that they were paid laborers who took great pride in their work and were not slaves, as was previously thought. Employer Expectations. Alternatively, if our radiocarbon age estimations were in error for some reason, we had to assume that many other dates obtained from Egyptian materials were also suspect. The 'old-kingdom' construction techniques can be seen at other locations around the world.

Pyramid of Khafre is in background. It was an odd sensation climbing over the Great Pyramid, looking for minute flecks of charcoal or other datable material, loaded down with cameras, scales, notebooks, and forms with entries for sample number, site, monument, area, feature, material charcoal, reed, wood, etc. It was and the Edgar Cayce Foundation, named for an early twentieth-century psychic who claimed that the Sphinx and Khufu's Great Pyramid were built in 10, B. Old friends and supporters of the deceased psychic had visited Giza in the early s and several of them were willing to put their beliefs to the test by radiocarbon dating the Great Pyramid. Archaeologists believe it is the work of the Old Kingdom Dynasty 4 society that rose to prominence in the Nile Valley from ca. The radiocarbon dates from monuments spanning Dynasty 3 Djoser to late Dynasty 5 Unas , averaged years older than the Cambridge Ancient History dates of the kings with whom the pyramids are identified. In spite of this discrepancy, the radiocarbon dates confirmed that the Great Pyramid belonged to the historical era studied by Egyptologists. In dealing with the year discrepancy, we had to consider the old wood problem. In we thought it was unlikely that the pyramid builders consistently used centuries-old Egyptian wood as fuel in preparing mortar. Ancient Egypt's population was compressed in the narrow confines of the Nile Valley with a tree cover, we assumed, that was sparse compared to less arid lands.

In dealing with the year discrepancy, we had to consider the old wood problem. In we thought it was unlikely that the pyramid builders consistently used centuries-old Egyptian wood as fuel in preparing mortar. Ancient Egypt's population was compressed in the narrow confines of the Nile Valley with a tree cover, we assumed, that was sparse compared to less arid lands.

We expected that by the pyramid age the Egyptians had been intensively exploiting wood for fuel for a long time and that old trees had been harvested long before. The results left us with too little data to conclude that the historical chronology of the Old Kingdom was in error by nearly years, but we considered this at least a possibility.

Alternatively, if our radiocarbon age estimations were in error for some reason, we had to assume that many other dates obtained from Egyptian materials were also suspect. This prompted a carbon dating giza pyramids, larger study. The Project. During samples were collected from the Dynasty 1 tombs at Saqqara to the Djoser pyramid, the Giza Pyramids, and a selection of Dynasty 5 and 6 and Middle Kingdom pyramids.

Samples were also taken from our excavations at Giza where two largely intact bakeries were discovered in The calibrated dates from the Old Kingdom pyramid samples tended to be to years older than the historical dates for the respective kings and about years younger than our dates. The number of dates from both and was only large enough to allow for statistical comparisons for the pyramids of Djoser, Khufu, Khafre, and Menkaure. There are two striking results.

First, there are carbon dating giza pyramids discrepancies between and dates for Khufu and Khafre, but not for Djoser and Menkaure. Second, the dates are scattered, varying widely even for a single monument. For Khufu, they scatter over a range of about years. By contrast, we have fair agreement between our historical dates, previous radiocarbon dates, and our radiocarbon dates on reed for the Speaking, online dating sites tampa think 1 tombs at North Saqqara.

We also have fair agreement between our radiocarbon dates and historical dates for the Middle Kingdom. Eight calibrated dates on straw from the pyramid of Senwosret II ranged from years older to 78 years younger than the historical dates for his reign, with four dates off by only 30, 24, 14, and three years. Significantly, the older date was on charcoal. Old Kingdom Problem.

If the Middle Kingdom radiocarbon dates are okay, why are the Old Kingdom ones from pyramids so problematic? The pyramid builders used older cultural material, whether out of expedience or to make a conscious connection between their pharaoh and his predecessors.

In galleries under the pyramid of the Dynasty 3 pharaoh Djoser more than 40, stone vessels were found. Inscriptions on them included most of the kings of Dynasty 1 and 2, but Djoser's name occurred only once. Perhaps Djoser gathered up the vases from the year-old Archaic tombs at North Saqqara.

In Dynasty 12, Amenemhet I actually took bits and pieces of Old Kingdom tomb chapels and pyramid temples including those of the Giza Pyramids and dumped them into the core of his pyramid at Lisht.

At Giza, south of the Sphinx, we are excavating remains of facilities for storage and production of fish, meat, bread, and copper that date to the middle and end of Dynasty 4, when the pyramids of Khafre and Menkaure were under construction. Three of the eight dates from samples carbon dating giza pyramids here are almost direct hits on Menkaure's historical dates, Speed dating in saint. The other five, however, range from to years older.

Our radiocarbon dates from the site suggest that, like those from the pyramids, the dates on charcoal from the settlement scatter widely in time with many dates older than the historical estimate. The pyramid builders were carbon dating giza pyramids recycling their own settlement debris.

It may have been premature to dismiss the old wood problem in our study. Do our radiocarbon dates reflect the Old Kingdom deforestation of Egypt? Did the pyramid builders devour whatever wood they could harvest or scavenge to roast tons of gypsum for mortar, to forge copper chisels, and to bake tens of thousands of loaves to feed the mass of assembled laborers.

The giant stone pyramids in the early Old Kingdom may mark a major consumption of Egypt's wood cover, and therein lies the reason for the wide scatter, increased antiquity, and history-unfriendly radiocarbon dating results from the Old Kingdom, especially from the time of Djoser to Menkaure. In other words, it is the old-wood effect that haunts our dates and creates a kind of shadow chronology to the historical dating of the pyramids.

It is the shadow cast by a thousand fires burning old wood. While the multiple old wood effects make it difficult to obtain pinpoint age estimates of pyramids, the David H. Koch Pyramids Radiocarbon Project now has us thinking about forest ecologies, site formation processes, and ancient industry and its environmental impact--in sum, the society and economy that left the Egyptian pyramids as hallmarks for all later humanity.
