A quantitative analysis of 150 Mesolithic dwellings in Norway, dated to between 9500 and 4000 cal bc, forms the core of a chronological and regional study based on fifteen variables, including floor size and shape, floor modifications and wall features, internal hearths, numbers and distribution of artefacts, traces of maintenance or reuse, and the number of dwellings per site. The study identifies a distinct change in dwelling traditions between the Early and Middle Mesolithic, around 8000 cal bc. Tents are typical of the Early Mesolithic, whereas remains of pit houses dominate in all later phases of the Mesolithic. The study also sheds light on variability in dwelling traditions after 8000 cal bc, which appears to relate to changes in social structure, growing territoriality, and regional differences.

This article discusses the construction details of the mounds erected over large Viking ship burials in Norway and shows that they form an integral part of mortuary practice. Moreover, elements of the construction that are potentially unique to this type of monument are repeated, suggesting a knowledge of the properties of materials and their inter-relationships within the mounds. Here, referencing between and within the mounds is considered alongside the connections these soils, sediments, and other earth-sourced materials contained in relation to the cultural landscape. The selection of such materials and the location of the burials in the landscape were fundamental to the creation of a performative scene for the burial rites, and for establishing a desired, interlinked, social memory.

The point of departure for this article is the excavation of two burial mounds and a trackway system in Bamble, Telemark, Norway. One of the mounds overlay ard marks, which led to speculation as to whether the site was ritually ploughed or whether it contained the remains of an old field system. Analysis of the archaeometric data indicated that the first mound was related to a field system, while the second was constructed 500–600 years later. The first mound was probably built to demonstrate the presence of a kin and its social norms, while these norms were renegotiated when the second mound was raised in the Viking Age. This article emphasizes that the ritual and profane aspects were closely related: mound building can be a ritualized practice intended to legitimize ownership and status by the reuse of domestic sites in the landscape. Further examples from Scandinavia indicate that this is a common, but somewhat overlooked, practice.

This article discusses the chronology and nature of the earliest Viking activity, based on a group of early burials from Norway containing Insular metalwork. By focusing on the geographical distribution of this material and applying the concept of locational and social knowledge, the importance of establishing cognitive landscapes to facilitate the Viking expansion is highlighted. It is argued that the first recorded Viking attacks were only possible after a phase in which Norse seafarers had acquired the necessarily level of a priori environmental knowledge needed to move in new seascapes and coastal environments. This interaction model opens the possibility that some of the early Insular finds from Norway may represent pre-Lindisfarne exploration voyages, carried out by seafarers along the sailing route of Nordvegr.

In this article, we examine aspects of the Postglacial colonization processes that took place in central Norway during the Early Mesolithic (c. 9500–8000 cal bc). The distribution of sites from this period shows that the colonizers approached and exploited two very different landscapes and resource situations—from archipelagic to alpine. Based on twelve artefact assemblages from central Norway we investigate how colonizing populations met the challenge posed by varying ecozones. Did they organize their settlements and technologies in similar ways or did they modify sites and activities in relation to the different locations? The aspects studied are site organization, artefact composition, projectiles, and lithic raw material use. It appears that the sites are of a similar size and structure across ecozones. Apart from some variations in tool composition, there is no evidence in the lithic material for any technical adaptation towards specific ecozones. We conclude that using a standard, generalized lithic technology, combined with high mobility and small group size, enabled the colonizing groups to overcome the risks and difficulties associated with settling and seeking out resources in new and unknown landscapes.

In 1904, a Viking Age ship was found and excavated in Oseberg, on the west side of the Oslo Fjord, south of Oslo, Norway. The skeletal remnants of two females buried onboard were anthropologically examined during the inter-war years. Questions surrounding their identities have prompted much speculation, and many people like to believe that one of the women could be Queen Åsa, the grandmother of Norway's first king. When the skeletons were reburied in 1948, a few smaller pieces were held back and stored in the Anatomical Institute at the University of Oslo. Those fragments have now been radiocarbon dated at 1220±40 and 1230±40 BP. Their similar δ13 = −21.6‰/−21.0‰ indicates that they both were nourished by a diet consisting primarily of terrestrial food and only to a lesser degree by fish. To answer the question of whether the two women were related, Dr Tom Gilbert at the Panum Institute in Copenhagen managed to obtain a DNA profile from the younger of the two, which profile indicates that her sample falls into the haplogroup U7. This finding is interesting, as this haplogroup is nearly absent in modern Europeans but is common in Iranians. Perhaps this could mean that the young lady's ancestors came from the district around the Black Sea, as Snorri Sturlusson notes in his Saga. Unfortunately, the bones from the older woman were too contaminated to provide a clear profile. Because there is reason to fear that the reburied skeletal material will slowly disintegrate in the coffins, some scholars desired that the mound be reopened in order to save the remains and to determine whether it is possible to obtain another DNA profile before such an opportunity is lost.

The application of medical scanning technologies to archaeological skeletons provides novel insights into the history and potential causes of osteoporosis. The present study investigated bone mineral density (BMD) in medieval skeletons from England and Norway. Comparisons between the two adult populations found no statistically significant differences. This compares with a modern fracture incidence for the femoral neck in women from Norway that is almost three times that in the UK. The pattern of age-related bone loss in medieval men was similar to that seen in men today. In contrast, the pattern in medieval women differed from that of modern young women. On average, medieval women experienced a decrease in BMD at the femoral neck of approximately 23 per cent between the ages of 22 and 35. These losses were partially recovered by age 45, after which BMD values show a decline consistent with post-menopausal bone loss in modern western women. A possible explanation of the rapid decline in BMD in young medieval women is bone loss in connection with pregnancy and lactation in circumstances of insufficient nutrition.
