Radiocarbon dating sphinx
John Anthony West, an author and alternative Egyptologist, investigated Schwaller de Lubicz's ideas further and, in 1989, sought the opinion of Robert M.
Schoch, a geologist and associate professor of natural science at the College of General Studies at Boston University.
The 1984 results left us with too little data to conclude that the historical chronology of the Old Kingdom was in error by nearly 400 years, but we considered this at least a possibility. During 1995 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.
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. Samples were also taken from our excavations at Giza where two largely intact bakeries were discovered in 1991.
The recent photo shows the extensive restorations done around the neck and edges of the headress.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.Egypt was an arid land before the time of the first Pharaohs.In recent times it has only taken a couple of decades for the Sphinx to be buried up to its neck by sand blown in from the desert, as can be seen in this photo from the 19th Century.
