The Italy_Imperial assemblage sits squarely in the age when Rome transformed from a Mediterranean power into an empire of cities and seas (27 BCE–400 CE). Archaeological contexts include urban and suburban cemeteries—Isola Sacra, Necropoli Salaria (Via Paisiello and Viale Rossini), Palestrina Antina, Monterotondo, Mazzano Romano, Centocelle, Casale del dolce, Marcellino & Pietro, and ANAS excavation locations—each a pulse point in the living landscape of Imperial Italy. Material culture from these sites (funerary goods, inscriptions, burial types) indicates continuity with Late Republican and early Imperial practices but also the layered presence of migrants, sailors, merchants and rural arrivals.
Genetically and archaeologically, this population appears as a palimpsest: a base of long-standing Italian and central Mediterranean ancestry overlaid by eastern Mediterranean and wider imperial-era mobility. Limited evidence suggests regular movement along maritime and overland routes to and from the eastern Mediterranean and beyond, but archaeological data indicate many individuals were integrated into local urban communities. The 48 sampled individuals provide moderately robust resolution of population structure in the Rome area, yet urban sampling can over-represent mobile individuals and certain socioeconomic groups. Where sample counts are lower for individual sites, interpretations must remain cautious.
