Social stratigraphy in Late Iron Age Switzerland: Analysis of human remains from Münsingen

Abstract

The Iron Age cemetery of Münsingen in Switzerland with 220 abundantly equipped burials marked a milestone for Iron Age research. The horizontal spread throughout the time of its occupancy laid the foundation for the chronology system of the Late Iron Age. Today, skulls of 77 individuals and some postcranial bones are still preserved and were investigated anthropologically. Collagen was analysed via stable isotope mass spectrometry (carbon, nitrogen, and sulphur). Additionally, some bones showed pathologies or lesions which were examined via imaging and histological methods. The aim of the study was to obtain biological-anthropological information about the Iron Age population. There are significant differences between males and females in δ13C and δ15N values. This points to a gender restriction in the access to animal protein with males having more access to meat and dairy products. Differences in δ15N values were also observed for different age classes. δ34S values indicate a terrestrial-based diet with no significant intake of marine or freshwater fish. Seven adults with enriched δ34S values might have immigrated to Münsingen, four of which were found in the oldest part of the cemetery. Furthermore, possible changes of the vegetation are indicated by the more positive stable carbon ratios in the later phases. The results lead to the suggestion that especially males buried with weapons might have played a special role in the Iron Age society. Also, skull trepanations in two males suggest that surgical treatment of injuries caused by weapons may have been performed
