Provenancing Rune Carvers on Bornholm through 3D-Scanning and Multivariate Statistics of the Carving Technique.

In 2017, eight runestones on Bornholm were scanned in 3D and the microtopography of the grooves was analysed by multivariate statistical methods. One of the stones was previously not known to runological research. The aim of this paper is to compare the carving technique of the Bornholm runestones with runestones from Swedish regions to shed light on old issues concerning Bornholm's links with other regions in and around the Baltic Sea. The rune carvers are important agents in this, as the runestones are often related to issues including landholding, Christianization, possible Swedish influences, and the inclusion of Bornholm into the Danish realm. In addition, rune carvers as native writers were intimately connected to the introduction of literacy. The results of this study indicate that the rune carvers did not cooperate much with carvers from the islands of Öland and Gotland, whereas Södermanland, among the Swedish mainland provinces, was their first choice.
