This dissertation examines human mobility and population interactions at the Imperial Roman (ca. 1st–3rd c. CE) sites of Isola Sacra (SCR) at Portus, Velia in the Cilento of Italy, and Rue Jacques Brel Necropolis (JBR) in Saintes, France. Isotopes of oxygen (18Oc) and strontium (87Sr/86Sr) are used to assess instances of human mobility from the enamel of second molars (M2), providing a gauge of movement after age ~7–8 years. Nonmetric traits are employed in conjunction with isotopic perspectives to examine the nature of biological affinities and phenetic divergence between these three sites.
Isotopic results of this study indicate that a significant number of individuals, including females and children, were mobile towards the sites at which they were ultimately interred, with the highest estimates of mobility provided by 18Oc seeing rates between 25%–38% across the three sites. 87Sr/86Sr results provided lower estimates of mobility ranging from zero cases at Velia to 30% at JBR, while combined 18Oc and 87Sr/86Sr analyses provided the lowest estimates of mobility ranging from zero cases at Velia to 20% at JBR. Such results suggest that a combined isotope approach may not necessarily increase the degree of mobility discrimination, bringing into question issues of regional homogeneity and overlap in 18Oc and 87Sr/86Sr values for the regions examined. A further examination of 18Oc variation in M1 vs. M2 vs. M3 for a sub-sample of 20 individuals indicates that childhood mobility was taking place at Portus.
Nonmetric trait analysis provides insight to the nature of biological population similarity and divergence. Across the three sites SCR is the most similar to JBR and Velia, while Velia and JBR are the most dissimilar. The nature of these similarities suggests that overall the biological background of the people interred at JBR, SCR, and Velia is similar, but with unique regional phenetic differences indicating distinct biological populations at all three sites.
Using these multiple lines of evidence this dissertation emphasizes a significant degree of mobility and population heterogeneity across the Roman landscape. It is evident from the research findings presented here that with the expanding Roman empire mobility and population interaction remained staples of Roman life. / Dissertation / Doctor of Philosophy (PhD)
