フィレンツェ大学やハーバード大学などの研究者が古代DNAを用いて、ポンペイの住民に関する従来の見解を覆しました。DNA解析により、これまで推測されていた性別や家族関係が異なることが判明し、ポンペイが移民を多く含む多文化的な都市だったことが示されました。例えば、同じ家族とされた4人の遺体に遺伝的な繋がりはなく、社会構造がより複雑であったことが明らかになりました。

Highlights

•We generated genome-wide data from skeletal material in Pompeii plaster casts
•The data contradict prior narratives about the victims’ identities and relationships
•Pompeiian individuals mainly descended from recent eastern Mediterranean immigrants

Summary

The eruption of Somma-Vesuvius in 79 CE buried several nearby Roman towns, killing the inhabitants and burying under pumice lapilli and ash deposits a unique set of civil and private buildings, monuments, sculptures, paintings, and mosaics that provide a rich picture of life in the empire. The eruption also preserved the forms of many of the dying as the ash compacted around their bodies. Although the soft tissue decayed, the outlines of the bodies remained and were recovered by excavators centuries later by filling the cavities with plaster. From skeletal material embedded in the casts, we generated genome-wide ancient DNA and strontium isotopic data to characterize the genetic relationships, sex, ancestry, and mobility of five individuals. We show that the individuals’ sexes and family relationships do not match traditional interpretations, exemplifying how modern assumptions about gendered behaviors may not be reliable lenses through which to view data from the past. For example, an adult wearing a golden bracelet with a child on their lap—often interpreted as mother and child—is genetically an adult male biologically unrelated to the child. Similarly, a pair of individuals who were thought to have died in an embrace—often interpreted as sisters—included at least one genetic male. All Pompeiians with genome-wide data consistently derive their ancestry largely from recent immigrants from the eastern Mediterranean, as has also been seen in contemporaneous ancient genomes from the city of Rome, underscoring the cosmopolitanism of the Roman Empire in this period.
