In order to consolidate and document this knowledge the Centre approached me proposing a joint project between the Centre and the University of Southern Denmark. We decided to focus on flax and linen in 2010.

A shared frailty model was fitted with 2.7 million persons aged 30-81 years in 2,121 parishes. Residence in areas with high population density increased all-cause mortality for all age groups. For older age groups, residence in areas with higher proportions of unemployed persons had an additional effect. Area-level factors explained considerably more variation in mortality among the elderly than among younger generations. Overall this study suggests that structural prevention efforts in neighborhoods could help reduce mortality when mediating processes between area-level socioeconomic status, population density and mortality are found.

Public concern exists about this potential hazard and researchers agree that further research is required on this field. The objective of the study was to investigate the association between waste landfill location and congenital anomalies risk in Denmark. The study was a multisided epidemiological geographical comparison study of risk of congenital anomalies combined and congenital anomalies of the cardiovascular and nervous systems with maternal residence in the vicinity of 48 Danish waste landfills compared with those living further away in the years 1997 to 2001. We used routine health and population data in Geographical Information System (GIS) to investigate the risk. The subjects were 2,477 live birth with congenital anomalies. All relative risks in the proximal zones of 0-2 km were set to 1 for comparison. For all anomalies combined relative risk in the middle zones of 2-4 km joint was 0.991 and in the distal zones of 4-6 km joint the relative risk was 1.013. For congenital anomalies of the nervous system, the relative risk in the middle zones was 1.226 and in the distal zones 1.113. For congenital anomalies of the cardiovascular system, the relative risk in the middle zones was 0.926 and in the distal zones 0.854. This result was not supported by the aggregated risk ratio mean. We found no association between waste landfill location and congenital anomalies combined or of the nervous system. However, we found small excess risk for congenital anomalies of the cardiovascular system. No causal mechanisms are available to explain these findings, but alternative explanations include approximated birth rates and residual confounding. It is our recommendation that more comprehensive multisided studies will be executed to examine the safety of waste landfills.

The excavation formed part of the ERC-funded research project called ANTHEA, focusing on the deep history of anthropogenic heathlands. It was conducted by Aarhus University in collaboration with Holstebro Museum and Moesgaard Museum. The aim was to test a new method of sampling pollen data from different construction stages in a burial mound and comparing them with pollen data from nearby lake sediments with a view to improving our understanding of prehistoric anthropogenic heathland dynamics. Prior to the excavation, soil cores were collected from two nearby peat sediments as well as six burial mounds (including Store Vejlhøj) within a 1 km range of Lake Skånsø, where previous pollen analyses had been carried out. Based on these preliminary corings, Store Vejlhøj was selected for further archaeological investigation. A dispensation for excavatin...

In order to consolidate and document this knowledge the Centre approached me proposing a joint project between the Centre and the University of Southern Denmark. We decided to focus on flax and linen in 2010. The group of authors consists of Birgit Thomsen from Ribe Viking Centre, and from the University I participated together with students Amanda Appel and Sara Gjerlevsen. In fact the students did much of the practical work together with Birgit Thomsen, and were responsible for describing the results in this report. Later we were fortunate to have Stina Andresen, archaeologist and curator at Varde Museum, joining the project. The subject of her master thesis was exactly flax during the Iron and Viking Ages (Andresen 2005), and Stina contributed much valuable knowledge to the project, not least on the archaeology of flax processing. It was a very inspiring collaboration for all parties involved. In following the entire process from seed to shirt, the project ended up being the most comprehensive that we have been able to find in the literature, although this was never a goal in itself. The archaeology programme, which is taught at the University of Southern Denmark, is in maritime archaeology. One may wonder why we engage in an experimental project on flax. To this we can say that although our students are well-read in maritime aspects of past societies, they are trained foremost as archaeologists. This means that their future jobs are not limited to wreck diving, but that they can take on broader aspects of the profession. We teach a master programme, and the students enter with a range of undergraduate degrees from around the world. Therefore it was natural for us to go into this project. On the maritime aspect of archaeology we have at least gained valuable insight, and a new found respect, on sail making through this work. One main lesson from the project is perhaps that the historical visitor centres, such as Ribe Viking Centre, have a vast practical experience and knowledge, which is important to archaeology, but that it is rarely utilized in a more controlled setting. Flax has been grown annually at the Centre for more than 15 years. With this report we have been able to document some of the experience gained at the Centre, and also to put that experience into the context and perspective of professional archaeology. Not least in that respect it has been an edifying project to participate in. With the enthusiasm of the participants and the inspiring setting the work was conducted it, it was even fun.
