The researchers exploited the origins of a set of Roman-age decapitated bodies, found by York Archaeological Trust (YAT) at Driffield Terrace in the city, and found they included a Middle Eastern body alongside native Europeans.
Archaeologists have speculated that the skeletons belonged to gladiators, although they could also have been soldiers or criminals. Several suffered perimortem decapitation and were all of a similar age – under 45 years old. Their skulls were buried with the body, although not positioned consistently – some were on the chest, some within the legs, and others at the feet.
Though examining the skeletons revealed much about their lives – including childhood deprivation and injuries consistent with battle trauma – it was the pioneering genomic analysis that helped researchers to piece together the origins of the men. The research is published in Nature Communications.
From the skeletons of more than 80 individuals, seven were selected for whole genome analyses. Despite variations in isotope values which suggested that some of the individuals lived their early lives outside Britain, most had genomes which were similar to an earlier Iron Age woman from Melton, East Yorkshire. The poor childhood health of the men suggests they were from disadvantaged households, though their robust skeletons and healed traumas, indicate that they were used to wielding weapons.
However, the nearest modern descendants of these Roman British men live in Wales rather than Yorkshire. The researchers also studied a male skeleton from a Christian Anglo-Saxon cemetery in the village of Norton, Teesside, which was found to have genes more closely aligned to modern East Anglia and Dutch individuals highlighting the impact of later migrations on the genetic makeup of the earlier Roman British inhabitants.
One of the decapitated Romans had a markedly different story, however. Of Middle Eastern origin, he grew up in the region of modern day Palestine, Jordan or Syria before migrating to the British Isles and meeting his death in York.
As well as the University of York, the multi-disciplinary scientific analysis involved scientists from YAT and Trinity College, Dublin, as well as the universities of Durham, Reading and Sheffield, University College London and the University Medical Centre in Utrecht. The research ateam lso included experts from York Osteoarchaeology Ltd, City of York Council and the Natural History Museum.
The Roman burial samples were all male, under 45 years old and most had evidence of decapitation. They were taller than average for Roman Britain and displayed evidence of significant trauma potentially related to interpersonal violence. All but one would have had brown eyes and black or brown hair but one had distinctive blue eyes and blond hair similar to the single Anglo-Saxon individual.
The demographic profile of the York skeletons resembles the population structure in a Roman burial ground believed to be for gladiators at Ephesus. But the evidence could also fit with a military context -- the Roman army had a minimum recruitment height and fallen soldiers would match the age profile of the York cemetery.
Professor Matthew Collins, of the BioArCh research facility in the Department of Archaeology at York, who co-ordinated the scientific analysis, said: “Whichever the identity of the enigmatic headless Romans from York, our sample of the genomes of seven of them, when combined with isotopic evidence, indicate six to be of British origin and one to have origins in the Middle East. It confirms the cosmopolitan character of the Roman Empire even at its most northerly extent.
“This is the first refined genomic evidence for far-reaching ancient mobility and also the first snapshot of British genomes in the early centuries AD, indicating continuity with an Iron Age sample before the migrations of the Anglo-Saxon period.”
