Test results from Middle Kingdom pyramid (Senwosret II).Ancient Egypt’s population was restricted to the narrow confines of the Nile Valley with, we assume, a sparse cover of trees.In spite of this discrepancy, the radiocarbon dates confirmed that the Great Pyramid belonged to the historical era studied by Egyptologists. Koch Foundation supported us for another round of radiocarbon dating.We broadened our sampling to include material from: We also took samples from our Giza Plateau Mapping Project Lost City excavations (4th Dynasty), where we discovered two largely intact bakeries in 1991.We thought that it was unlikely that the pyramid builders consistently used centuries-old wood as fuel in preparing mortar.The 1984 results left us with too little data to conclude that the historical chronology of the Old Kingdom was wrong by nearly 400 years, but we considered this at least a possibility.Four of the Senwosret II dates were only off by 30, 24, 14, and three years.
Interest in Egyptian chronology is widespread in both popular and scholarly circles.We then compared our results with the mid-point dates of the kings to whom the monuments belonged (Cambridge Ancient History, 3rd ed.).The average radiocarbon dates were 374 years earlier than expected.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 (1897-1878 BC) ranged from 103 years older to 78 years younger than the historical dates for his reign.
It is likely that, by the pyramid age, the Egyptians had been intensively exploiting wood for fuel for a long time.
