From Smithsonian Magazine:
Sometime between 130 and 360 C.E., a 25- to 35-year-old man in what’s now Cambridgeshire, England, died by crucifixion at the hands of the Roman Empire. His skeleton—found with a telltale nail hammered through its heel bone—represents one of the few surviving physical traces of the ancient punishment, report David Ingham and Corinne Duhig for British Archaeology magazine...Archaeological evidence of crucifixion is rare, as victims often didn’t receive a proper burial. Additionally, most crucifixions used rope rather than nails to bind the condemned to a cross.According to BBC News, scholars know of only three other possible physical examples of crucifixion during the ancient era: one found in La Larda in Gavello, Italy; one from Mendes in Egypt; and one from Giv’at ha-Mivtar in north Jerusalem...Excavators discovered the remains, dubbed Skeleton 4926, during a dig conducted ahead of construction in the village of Fenstanton in 2017, reports PA Media. The community stands along the route of the Via Devana, an ancient Roman road that connected Cambridge to Godmanchester...Skeleton 4926 showed evidence of severe suffering endured before death. According to a separate Cambridge statement, the man’s legs bore signs of infection or inflammation, possibly caused by binding or shackles. Six of his ribs were fractured, likely by blows from a sword.
