Archaeological contexts and funerary landscapes in Rome between the mid-3rd and early 8th centuries CE record a city negotiating empire, invasion, and reinvention. The 24 sampled individuals come from prominent urban burial complexes — Crypta Balbi, San Ercolano, the churches of Marcellino & Pietro, interments near the Mausoleo di Augusto, and graves on the Celio hill. These sites capture phases from the Crisis of the Third Century (centering on 260–270 CE) through the Lombard migrations and early medieval reorganization around 700 CE.
Material culture — grave goods, burial orientation, and stratigraphic relationships — indicates both continuity with Roman funerary practice and the introduction of new rites over these centuries. Archaeological data indicates episodes of disruption (e.g., cemetery contractions, re-used monuments) but also sustained local occupation. Limited evidence suggests some newcomers integrated into urban neighborhoods rather than forming segregated enclaves.
Genetically, the assemblage should be read as a city snapshot, not a demographic census: the sampled individuals derive from specific burial contexts within Rome and reflect the social and spatial biases of urban cemeteries. While many genetic lineages echo long-standing Mediterranean and European ancestries, the presence of haplogroups with eastern Mediterranean and North African associations hints at Rome’s enduring role as a magnet for mobility. Interpretations must remain cautious: archaeological sampling and preservation bias affect which people are visible to both archaeology and ancient DNA.
