800 Years, human sacrifice, Kent UK, technology, anthropology, archeology, technology: Wow … that much from some old teeth.
Andrew Millard of Durham University analysed all suitable teeth from 25 individuals. Here’s the geographical breakdown of the sacrificial victims’ area of origin:
32% southern Norway or Sweden
20% western Mediterranean
The reason that you do more than one tooth from the same individual is that teeth form in sequence during gestation, childhood and adolescence. If you move or change your diet during that period, this shows up in the isotope ratios of whatever tooth your body is making at the time. This gave particularly interesting results in the case of an old woman whose disarticulated skull was redeposited in the Late Bronze Age charnel pit discussed above. She was born in Scandinavia, moved to northern Britain as a child, lived a long life and finally ended up as a prop in a religious ritual on Thanet.
