The Bluetooth Runestone in Lund: Viking script meets a modern technology
Standing near the old cathedral in the southern Swedish city of Lund, the Bluetooth Runestone is both a rare example of Scandinavian epigraphy and an important piece in the history of the naming of a modern technology. According to Atlas Obscura's record of the site, the stone is dated to the middle of the 10th century and is attributed to the Viking king Harald "Bluetooth" Gormsson.
The runes on the surface of the stone are written in Old Norse and contain a sentence traditionally read as "Harald united the kingdoms of Denmark and Norway." That reading came out of epigraphic study of the stone's text. Scandinavian archaeologists say that the stone's original site is not where it now stands, and that it may have been moved to Lund after originally being recovered at Jelling in Denmark.
King Harald played an important role in the Christianisation of Denmark during the 10th century. Having converted to Christianity around 965, Harald followed that decision with a reorganisation of the religious and political structures across his territories. That process was, as Atlas Obscura notes, an important moment in the longer transition in the Scandinavian region between paganism and Christianity.
The origin of the king's byname is not clearly established by historical documents, but the most common interpretation is that it refers to the dark colour of a dead tooth. Some historians have suggested that the nickname could mean "dark-skinned." Whichever is correct, the byname became popular again through 19th-century European Romantic history writing, and that was the basis of its present-day use.
The stone's connection to a modern technology came about in 1996. At the time, Intel engineer Jim Kardach suggested a codename for a wireless communication standard then being developed jointly by Ericsson, Nokia and Intel. Kardach explained that he had been reading Frans Bengtsson's novel "The Long Ships" and felt that Harald Bluetooth's role in uniting different kingdoms could stand as a symbol for a project aiming to bring different companies together under a single standard.
The Bluetooth logo was created by its designer by combining two letters from the Old Scandinavian runes. The runic forms of "H" and "B", which are ᚼ and ᛒ, stand for the initials of Harald Bluetooth's name. This visual design developed as a deliberate bridge between technology and history, and is today found on billions of devices worldwide.
The stone's location in Lund is at the edge of a town square and is displayed within a public exhibition design. The city council placed a glass protection structure around the stone in 1985 to preserve it. The continuous temperature control of that structure prevents the rune markings on the stone's surface from weathering.
Professor Lena Peterson, a runologist at Lund University, says that the most recent epigraphic studies of the stone's surface were completed in 2018. Those studies showed that some of the symbols on the surface of the stone had previously been read incorrectly, and that on the correct reading the text opens with the phrase "This stone is in memory of Harald." Peterson said this new reading made the monumental function of the stone clearer.
According to Atlas Obscura, the square where the stone is displayed receives around 80,000 visitors a year. Its central location in the town makes the structure a popular meeting point both for visitors interested in history and technology and for local residents. Lund University has placed informational boards next to the stone explaining the development of modern Bluetooth technology.
The Bluetooth Runestone is one of the rare cases in which a written monument from the past has been turned into the cultural reference of a modern technology company. The structure offers a multi-layered historical narrative, both as a symbol of the religious and political transitions of 10th-century Scandinavia and as a starting point for the visual identity of 21st-century communications.
