Who was in Harold Bluetooth's army? Strontium isotope investigation of the cemetery at the Viking Age fortress at Trelleborg, Denmark

The circular fortress of Trelleborg on Zealand in Denmark is well known as a military camp with a key role in the formation of the Danish state under Harald Bluetooth in the tenth century AD. Taking a sample of 48 burials from the fort, strontium isotope analysis once again demonstrates its ability to eavesdrop on a community: at Trelleborg, the young men in its cemetery were largely recruited from outside Denmark, perhaps from Norway or the Slavic regions. Even persons buried together proved to have different origins, and the three females sampled were all from overseas, including a wealthy woman with a silver casket. Trelleborg, home of Harald Bluetooths army, was a fortress of foreigners with vivid implications for the nature of his political mission.

Patterns of violence-related skull trauma in neolithic southern scandinavia

This article examines evidence for violence as reflected in skull injuries in 378 individuals from Neolithic Denmark and Sweden (3,900-1,700 BC). It is the first large-scale crossregional study of skull trauma in southern Scandinavia, documenting skeletal evidence of violence at a population level. We also investigate the widely assumed hypothesis that Neolithic violence is male-dominated and results in primarily male injuries and fatalities. Considering crude prevalence and prevalence for individual bones of the skull allows for a more comprehensive understanding of interpersonal violence in the region, which is characterized by endemic levels of mostly nonlethal violence that affected both men and women. Crude prevalence for skull trauma reaches 9.4% in the Swedish and 16.9% in the Danish sample, whereas element-based prevalence varies between 6.2% for the right frontal and 0.6% for the left maxilla, with higher figures in the Danish sample. Significantly more males are affected by healed injuries but perimortem injuries affect males and females equally. These results suggest habitual male involvement in nonfatal violence but similar risks for both sexes for sustaining fatal injuries. In the Danish sample, a bias toward front and left-side injuries and right-side injuries in females support this scenario of differential involvement in habitual interpersonal violence, suggesting gendered differences in active engagement in conflict. It highlights the importance of large-scale studies for investigating the scale and context of violence in early agricultural societies, and the existence of varied regional patterns for overall injury prevalence as well as gendered differences in violence-related injuries.

Isotopic investigation of human provenience at the eleventh century cemetery of Ndr. Grødbygård, Bornholm, Denmark

Bornholm is a Danish island almost in the center of the southern Baltic Sea. The strategic location of the island, its rich archeology, and its complex geology make it an intriguing location for the isotopic study of past human mobility. The focus of this study is on the large cemetery of Ndr. Grødbygård in the southern part of the island, which dates to the eleventh century AD and contains 553 individuals in 516 graves. The majority of the burials were in a supine position oriented west–east, with the heads to the west, following the tradition of that time. In contrast to the Christian traditions, however, the graves at Grødbygård were richly equipped by Scandinavian standards and some of the burial practices more closely resembled those from the Western Slavic region of the south (present day northeastern Germany and Poland). We have used isotopic analyses to examine the external relations and potential places of origin of the inhabitants of the cemetery. Strontium and oxygen isotope ratios in human tooth enamel provide a signature of place of origin and can be compared to the ratios of the place of burial to determine local or non-local origins. In the case of Bornholm, the local geology is quite complex, with a variety of rocks of different age and composition, resulting in a wide range of strontium isotope sources on the island, complicating the issue of identifying migrants. At the same time, Grødbygård provides an important example of the application of such methods in less than ideal conditions.

Chronology of the Danish Bronze Age Based on 14C Dating of Cremated Bone Remains

The relative Bronze Age chronology for Scandinavia was established as early as 1885. It is traditionally divided into 6 periods (I-VI). Earlier attempts to make an absolute Bronze Age chronology for southern Scandinavia were derived from burials and settlements and were mainly based on radiocarbon-dated charcoal or carbonized cereals, often with undefined archaeological periods. Here, we present high-precision 14C dating on burials with well-defined associated archae- ological periods in order to improve the absolute chronology of the Danish Bronze Age. Our results are in broad agreement with the traditional absolute chronology of the Danish Bronze Age. However, our results do indicate that the onset of period III likely occurred earlier than previously thought.

Galgedil: isotopic studies of a Viking cemetery on the Danish island of Funen, AD 800–1050

Galgedil is a Viking Age cemetery located in the northern part of the Danish island of Funen. Excavations at the site revealed 54 graves containing 59 inhumations and 2 cremation burials. Previous study of the remains to date has included light isotopes of carbon and nitrogen in collagen (10 samples) and the radiocarbon determination of the age of 8 samples. In addition, aDNA was investigated in 10 samples from the cemetery. Here we report the analysis of strontium isotopes in human tooth enamel as a signal of place of birth. Some 36 samples have been measured and non-local outliers identified. Baseline levels of strontium isotope ratios in Denmark are discussed and documented. Our study also includes an in-depth consideration of the bioarcheology of the skeletal remains in terms of demography, paleopathology, and taphonomy. The burials are evaluated in light of the available archeological, chronological, anthropological, and isotope information available.

Early neolithic skeletons from Bolkilde bog, Denmark

In 1946 two skeletons were found during peat-digging in Bolkilde bog in the north of the Danish island of Als. They have now been dated to the middle of the fourth millennium BC and are interpreted as ritual offerings of a fertility cult which went through from the early Neolithic to the time of Frej and Freja.
