The
Strontium Isotope Analysis Reveals Local Origins
To clarify the origins of the Esplanada group, a research team led by Julianne R. Stamer from Arizona State University employed strontium isotope analysis. This method examines the chemical signatures in tooth enamel, which reflect the geographical areas where individuals spent their childhood. The study, published in the Journal of Archaeological Science: Reports, analyzed samples from 66 of the shackled men and compared them to 97 other individuals buried in the same cemetery. The results indicated that over 95 percent of the Esplanada men had strontium signatures consistent with growing up in the Attica region, contradicting the theory that they were outsiders.
This new evidence reshapes the narrative surrounding the Esplanada group. If these men had been foreign mercenaries, a higher proportion of non-local strontium values would have been expected. Instead, their chemical profiles closely matched those of the broader Phaleron population, suggesting that the violence they experienced stemmed from internal community conflicts rather than external threats. While the study does not pinpoint the exact reasons for their execution, it underscores a harsh reality: the turmoil of that era in Athens was not solely the result of outside forces, but rather a reflection of the city's own societal struggles.
