As the researchers will report in tomorrow's issue of , they found that the Old Kingdom, which kicked off with Djoser's reign, began between 26 B.

As an archaeologist with 25 years of experience using C14 for the dating of excavated samples, I know what most archaeologists do when C14 produces a date which conflicts strongly with other evidence from a site : 1) run more dates on different samples from the same context, and then 2) put the aberrant dates down to some unidentified problem (usually in a footnote to the site report if mentioned at all).

This happens often in archaeology, even on sites and samples which were thought to be ideal for C14 dating.

In it, Rodger Sparks, a carbon dating expert from New Zealand, and William Meacham, archaeologist and Shroud researcher from Hong Kong, debated some of the theories that have been proposed regarding possible inaccuracies in the 1988 carbon dating test results.

Anyone who still believes that C14 dating has proven the Shroud to be medieval should be quickly disabused of that notion.

The researchers constructed a separate model for each of the three main Egyptian periods: Old Kingdom, Middle Kingdom, and New Kingdom. New Kingdom pharoah Rameses II, considered the greatest of the Egyptian kings by historians, clocks in between 12 B. In a Perspective accompanying the paper, archaeologist Hendrik Bruins of Ben-Gurion University of the Negev in Israel points out that one major controversy remains unresolved: the timing of the massive eruption of the volcanic island of Thera in the Aegean Sea, which transformed the history of the eastern Mediterranean and has important implications for understanding the relationship between Egypt and the Minoans, another powerful culture of the time. But radiocarbon and historical dating by University of Vienna archaeologist Manfred Bietak's team at Tell el-Dab'a in Egypt has concluded that the Thera eruption took place during the New Kingdom era.
