New interpretation of runic inscription reveals pricing in Viking age

A new interpretation of the runic inscription on the Forsa Ring (Forsaringen in Swedish), provides fresh insights into the Viking Age monetary system and represents the oldest documented value record in Scandinavia. The inscription describes how the Vikings handled fines in a flexible and practical manner. This is highlighted in research from the Department of Economic History and International Relations at Stockholm University, recently published in the Scandinavian Economic History Review.

"The Forsaringen inscription "uksa … auk aura tua" was previously interpreted to mean that fines had to be paid with both an ox and two ore of silver. This would imply that the guilty party had to pay with two different types of goods, which would have been both impractical and time-consuming," says Rodney Edvinsson, Professor of Economic History at Stockholm University, who conducted the study.

The Forsa Ring is an iron ring from Hälsingland, dated to the 9th or 10th century. The runic inscription on the ring describes fines for a specific offense, where payment was to be made in the form of oxen and silver. The ring is believed to have been used as a door handle and is currently the oldest known preserved legal text in Scandinavia. By changing the translation of the word "auk" from the previous interpretation "and" to the new interpretation "also," the meaning changes so that fines could be paid either with an ox or with two ore of silver. An ore was equivalent to about 25 grams of silver.

"This indicates a much more flexible system, where both oxen and silver could be used as units of payment. If a person had easier access to oxen than to silver, they could pay their fines with an ox. Conversely, if someone had silver but no oxen, they could pay with two ore of silver," says Rodney Edvinsson.

The new interpretation shows that the Vikings had a system where both oxen and silver served as units of payment. This system allowed for multiple types of units of accounts to be used concurrently, reducing transaction complexity and making it easier for people to meet their financial obligations. The new interpretation also aligns better with how the system functioned later according to later regional laws and is, according to Rodney Edvinsson, significant for our understanding of both Scandinavian and European monetary history.

"As an economic historian, I particularly look for historical data to be economically logical, that is, to fit into other contemporary or historical economic systems. The valuation of an ox at two ore, or 50 grams of silver, in 10th-century Sweden resembles contemporary valuations in other parts of Europe, indicating a high degree of integration and exchange between different economies," says Rodney Edvinsson.

He has previously contributed to developing a historical consumer price index extending back to the 13th century, but this new interpretation provides insights into price levels even earlier in history.

"The price level during the Viking Age in silver was much lower than in the early 14th century and late 16th century, but approximately at the same level as in the late 15th century and the 12th century, when there was a silver shortage," says Rodney Edvinsson.

The study highlights the importance of using modern economic theories to interpret historical sources. By combining economic theory with archaeological and historical findings, new opportunities for interdisciplinary research and a deeper understanding of early economic systems are opened up.

What Did Things Cost During the Viking Age?

According to the new interpretation, an ox would cost 2 öre of silver, about 50 grams of silver, during the Viking Age. This corresponds to roughly 100,000 Swedish kronor today, if compared to the value of an hour's work. The Forsa Ring's fine amount was therefore quite high. One öre was likely equivalent to about nine Arabic dirhams, a currency that circulated in large quantities among the Vikings. A common price for a thrall was 12 öre of silver, or approximately 600,000 Swedish kronor today. The wergild for a free man, i.e., the fine paid to the family of the murdered to avoid blood revenge, was much higher, around 5 kilos of silver, which is about 10 million Swedish kronor today. The significant difference in value between a thrall and a free man reflects the power dynamics between free individuals and thralls in a slave society.

The relevant inscription of the Forsa Ring translated to modern English: One ox and [also/or] two öre of silver to the staff for the restoration of a sanctuary in a valid state for the first time; two oxen and [also/or] four öre of silver for the second time; but for the third time four oxen and eight öre of silver.

Viking dentistry was surprisingly advanced

Widespread caries and toothache -- but also some dental work and filing of front teeth. Viking Age teeth from Varnhem bear witness to surprisingly advanced dentistry. This has been shown in a study carried out at the University of Gothenburg.

The study examined 3,293 teeth from 171 individuals among the Viking Age population of Varnhem in Västergötland, Sweden.

The site is known for extensive excavations of Viking and medieval environments, including tombs where skeletons and teeth have been preserved well in favorable soil conditions.

The research team from the University of Gothenburg's Institute of Odontology worked with an osteologist from Västergötland's Museum.

The skulls and teeth were transported to Gothenburg, where all the examinations were carried out.

The teeth underwent clinical examinations using standard dentistry tools under bright light.

A number of X-ray examinations were also performed using the same technique used in dentistry, where the patient bites down on a small square imaging plate in the mouth.

Caries and tooth loss

The results, which have been published in the journal PLOS ONE, show that 49% of the Viking population had one or more caries lesions.

Of the adults' teeth, 13% were affected by caries -- often at the roots.

However, children with milk teeth -- or with both milk and adult teeth -- were entirely caries-free.

Tooth loss was also common among adults. The studied adults had lost an average of 6% of their teeth, excluding wisdom teeth, over their lifetimes.

The risk of tooth loss increased with age.

The findings suggest that caries, tooth infections, and toothache were common among the Viking population in Varnhem.

However, the study also reveals examples of attempts to look after teeth in various ways.

"There were several signs that the Vikings had modified their teeth, including evidence of using toothpicks, filing front teeth, and even dental treatment of teeth with infections," says Carolina Bertilsson, a dentist and Associate Researcher, and the study's first-named and corresponding author.

Not unlike today's treatments

One sign of more sophisticated procedures was molars with filed holes, from the crown of the tooth and into the pulp, probably in order to relieve pressure and alleviate severe toothache due to infection.

"This is very exciting to see, and not unlike the dental treatments we carry out today when we drill into infected teeth. The Vikings seem to have had knowledge about teeth, but we don't know whether they did these procedures themselves or had help."

The filed front teeth may have been a form of identity marker.

In both this and previous studies, the cases found were male.

DNA from archaeological remains shows that immigration to Scandinavia was exceptional during the Viking period

A new study based on 297 ancient Scandinavian genomes analysed together with the genomic data of 16,638 present day Scandinavians resolve the complex relations between geography, ancestry, and gene flow in Scandinavia -- encompassing the Roman Age, the Viking Age and later periods. A surprising increase of variation during the Viking period indicates that gene flow into Scandinavia was especially intense during this period.

An international study coordinated from Stockholm and Reykjavik investigates the development of the Scandinavian gene pool over the latest 2000 years. In this effort the scientists relied on historic and prehistoric genomes, and from material excavated in Scandinavia. These ancient genomes were compared with genomic data from 16,638 contemporary Scandinavians. As the geographical origin and the datings were known for all these individuals, it was possible to resolve the development of the gene pool to a level never realised previously.

Dr Ricardo Rodríguez Varela at the Centre for Palaeogenetics*, who analysed all the data and extracted some of the ancient DNA used in the study, explains: "With this level of resolution we not only confirm the Viking Age migration. We are also able to trace it to the east Baltic region, the British-Irish Isles and southern Europe. But not all parts of Scandinavia received the same amounts of gene flow from these areas. For example, while British-Irish ancestry became widespread in Scandinavia the eastern-Baltic ancestry mainly reached Gotland and central Sweden."

The gene pool bounced back after the Viking period

Another new discovery in this study was what happened to the gene pool after the Viking period. The scientists were surprised to find that it bounced back in the direction of what it looked like before the Viking period migration.

Professor Anders Götherström at the Centre for Palaeogenetics, who is a senior scientist on the study, is intrigued: "Interestingly, the non-local ancestry peaks during the Viking period while being lower before and after. The drop in current levels of external ancestry suggests that the Viking-period migrants got less children, or somehow contributed proportionally less to the gene pool than the people who were already in Scandinavia."

Yet a new discovery was the history of the northern Scandinavian gene pool. There is a genetic component in northern Scandinavia that is rare in central and western Europe, and the scientists were able to track this component in northern Scandinavia through the latest 1000 years.

Dr Ricardo Rodríguez Varela comments, "We suspected that there was a chronology to the northern Scandinavian gene pool, and it did indeed prove that a more recent influx of Uralic ancestry into Scandinavia define much of the northern gene pool. But if it is recent, it is comparatively so. For example, we know that this Uralic ancestry was present in northern Scandinavia as early as during the late Viking period."

Based on well-known Swedish archaeological sites

The study is based on a number of well-known Swedish archaeological sites. For example, there are genomes from the 17th century warship Kronan, from the Viking and Vendel period boat burials in the lake Mälaren Valley, and from the migration period ring fortress Sandby borg on Öland.

Anders Götherström conclude: "We were working on a number of smaller studies on different archaeological sites. And at some point it just made sense to combine them into a larger study on the development of the Scandinavian gene pool.

Upcycling in the past: Viking beadmakers' secrets revealed

Ribe was an important trading town in the Viking Age. At the beginning of the 8th century, a trading place was established on the north side of the river Ribe, to which traders and craftsmen flocked from far and wide to manufacture and sell goods such as brooches, suit buckles, combs and coloured glass beads.

When glass became a scarce commodity in the Early Medieval time, coloured glass cubes -- so-called tesserae -- were torn down from mosaics in abandoned Roman and Byzantine temples, palaces and baths, transported North and traded at emporia towns such as Ribe, where the beadmakers melted them down in large vessels and shaped them into beads.

Until now, archaeologists have assumed that the pearl makers used the opaque white tesserae as raw material for the production of white, opaque beads.

Smart and sustainable production

And it is here that a geochemist and an archaeologist from Aarhus University together with a museum curator from Ribe have made a surprising discovery, which they have just published in the scientific journal Archaeological and Anthropological Sciences:

The chemical composition of white Viking beads from one of the earliest workshops showed that the glassmakers had found a more sustainable way to save time and wood for their furnaces: crush gold-gilded, transparent glass cubes, remelt them at low temperature, stir to trap air in the form of bubbles, and finally wrap the glass around an iron mandrel to form beads and voila! -- opaque white beads created in a short time using a minimum of resources.

The valuable ultra-thin sheets of gold stuck to the surface of the gold mosaic stone were of course salvaged by the glassmaker prior to remelting the glass, but the new findings show that some gold inevitably had ended up in the melting pot. Tiny drops of gold in the white beads, the many air holes (which is why the beads are opaque), as well as the fact that there are no chemical color tracers present, the researchers show that it was in fact the gold mosaic stones that was the raw material for the beads.

Such traces of gold were found not only in the white but also in the blue beads from the same workshop. Here the chemistry shows that the glassmaker's recipe consisted of a mixture of the blue and golden mosaic stones. Mixing them was necessary because the Roman blue mosaic stones contained high concentrations of chemical substances which made them opaque -- and therefore ideal for mosaics, but not for blue beads. By thus diluting the chemical substances, the result was the deep blue, transparent glass that we know from Viking Age beads.

Connoisseur craftsmanship

The bead maker in Ribe could instead have chosen to dilute the glass mixture with old shards from funnel beakers, which were also found in the workshop. But these turned out to be old, contaminated, Roman glass that had been remelted over and over again.

"And the glassmakers in Ribe were clearly connoisseurs who preferred the clearest glass they could get their hands on," says Gry Hoffmann Barfod from the Department of Geoscience at Aarhus University. She adds:

"For a geochemist, it has been a privilege to work with the fantastic material, and to discover how relevant the knowledge stored here is for our society today."

Interdisciplinary research

The interdisciplinary study was a collaboration between Gry Barfod, Søren Sindbæk, professor of archeology at the Danish National Research Foundation's Center for Urban Network Development (UrbNet) at Aarhus University, and museum curator Claus Feveile at the Museum of Southwest Jutland specializing in the Viking Age and Ribe's earliest history.

"The most outstanding achievements at the Ribe trading site were not just the products, but also the circular economy and their awareness to preserve limited resources" states professor Søren Sindbæk.

And museum curator Claus Feveile comments:

"These exciting results clearly show the potential of elucidating new facts about the vikings. By combining our high-resolution excavations with such chemical analyses I predict many more revelations in the near future."
