Distal cryptotephra found in a Viking boathouse: the potential for tephrochronology in reconstructing the Iron Age in Norway

Distal tephra deposits from Icelandic volcanic eruptions have been found in Norway and can be used to precisely date a variety of sedimentary environments. Tephrochronology has not yet been applied to archaeological investigations in Norway because tephra are generally not found as visible layers, but are present as very low concentrations of glass shards (i.e. cryptotephra). In this study, we present results from the analysis of cryptotephras found in an Iron Age boathouse in northern Norway. The boathouse was associated with the chieftain center at Borg on Vestvågøy in the Lofoten Islands. In 2003, a trench was excavated and the stratigraphy of the boathouse was described. Radiocarbon ages from cultural deposits show that it was constructed in the Early Iron Age c. AD 540–660 and the main period of use was at the end of the Iron Age between c. AD 1030 and AD 1270. Volcanic glass shards were isolated from sediment samples collected above and below the cultural deposit representing the main period of use. Electron microprobe analysis of the glass shards showed that the lower sample resembles the AD 860 Layer B tephra and the upper sample resembles tephra erupted from the Hekla volcanic system between AD 1104 and AD 1300. These tephrochronologic dates agree with the radiocarbon-derived dates and possibly further constrain the boathouse’s main period of use to c. AD 1030–1104. Our results demonstrate the value of using tephrochronology for archaeological studies in Norway and the potential for finding cryptotephra from other large explosive volcanic eruptions during the Iron Age.     

The role of Finland in the Swedish national and war economies during Sweden's period as a great power

The primary goal of this article is to present anti-Semitism as the underlying reason for the rejection of Israel-Jakob Schur's PhD dissertation at the University of Helsinki and at Åbo Akademi University in the late 1930s. The article analyzes the different stages of the processes and the ideological background and motives underpinning the rejections. Schur's antagonists were right-wing professors, some of whom sympathized with National Socialism and/or maintained contacts with eminent German anti-Semitic ideologues. The article analyzes the rhetoric of the written statements, which contain ideas of Christian anti-Semitism as well as other anti-Jewish stances. Moreover, the article demonstrates that Schur was regarded as an alien element in the Finnish academe, and the topic of his research – circumcision – was considered non-national from the perspective of Finnish science.     

Raw material distribution ‐ social space,social interaction

For the historical Inuit period long‐distance trading networks are well documented. An archaeological verification of similar behaviour in the Palaeo‐Eskimo period is being discussed for Disko Bay and West Greenland. On the basis of two extraction sites of killiaq, a silicified slate, new evidence is presented. The separation of two types of killiaq is used to describe a local and a regional distribution system. Killiaq from the Nuussuaq peninsula has travelled in large quantities over more than 600 km, whereas the other source from Angissat seems to be more local. The question though still remains whether we are dealing with a direct or an indirect procurement system.
