During the tenth century AD, Harald Bluetooth ruled Denmark from the royal seat at Jelling. The two extant Jelling mounds are traditionally associated with Harald's parents, Gorm and Thyra, about whom we know little. Unusually, the name Thyra appears on both Jelling runestones and on several others from the region. If all refer to the same person, she would be commemorated on more runestones than anyone else in Viking-Age Denmark. The authors use 3D-scanning to study rune carving techniques, combined with analyses of orthography and language, concluding that the Jelling 2 and Læborg stones are linked by the hand of the carver Ravnunge-Tue. The results suggest Thyra played a pivotal role in the emergence of the Danish state.

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.
