Diet at ancient Helike, Achaea, Greece based on stable isotope analysis: From the Hellenistic to the Roman and Byzantine periods

Despite the constant availability of terrestrial and marine resources at Helike, lagoon resources appear to have contributed to the diet only at certain times. This study demonstrates the importance of taking into account seismic activity and changing landscapes when reconstructing past diet over a large time span. What may be assumed to be cultural dietary differences may in fact be the result of environmental differences.
