Forty samples of bone and four of soil from the Hellenistic necropolis of Asine, in the northeast Peloponnese of Greece, and two samples of modern bone were analyzed. The concentrations of sodium, calcium, bromine, uranium, scandium, chromium, strontium, iron, cobalt, zinc, and barium were determined by thermal-neutron activation followed by highresolution gamma-ray spectroscopy. Concentrations of seven elements (bromine, uranium, scandium, chromium, iron, cobalt, and barium), present at high levels in ancient bone but only at low or undetectable levels in modern bone, were judged to be a result of contamination from the soil. Ribs were significantly more contaminated than femurs, as expected from the greater porosity of the former. Scatter plots of concentrations of strontium against concentrations of zinc in ancient femurs show two distinct clusters. They seem to be divided on the basis of date: one group consists mostly of remains of earlier, the other of later burials. They appear to reflect an increase in the consumption of red meat and coarse, unleavened bread during the later Hellenistic period.
