King Olaf's men? Contextualizing Viking burials at S:t Olofsholm, Gotland, Sweden

The discovery of burials at S:t Olofsholm, a site associated with the Saint Olaf cult on Gotland in Sweden, has enabled a bioarchaeological contextualization of medieval legends and sagas in conjunction with the archaelogical record. This study seeks to illuminate who were buried at S:t Olofsholm, through a biocultural lens, and whether these burials can be linked to folklore and sagas associated with the site. Five burials of possibly six individuals (cal. AD 980-1270) were assessed macroscopically and through stable isotope analysis (delta C-13, delta N-15, delta S-34, Sr-87/Sr-86, and delta O-18) of incremental dentine, bulk enamel, and bone samples. Sagas and legends associated with S:t Olofsholm mention episodes of conflict and contact involving King Olaf Haraldsson of Norway (later canonized as Saint Olaf), Gutes and Icelanders, and travels between Norway and Kyiv Rus. Two (or three) burials show signs of violent deaths, including evidence of sharp force trauma and burning. Isotope analyses indicate local and non-local signals, with possible links to southern Scandinavia, Britain, Iceland, the Baltics, and Kyiv Rus. In general, the evidence neither challenges nor confirms the legends and sagas associated with S:t Olofsholm. Instead, the findings illustrate the site's function as an early Christian place of worship within a wider Viking world that was characterized by travel and contact across the Baltic Sea, Scandinavia, and beyond. The burials at S:t Olofsholm are likely to be non-normative as indicated by their place of interment and the violent cause of death of most individuals.
