A Medieval/Early Modern Alpine Population from Zweisimmen,Switzerland: A Comparative Study of Anthropology and Palaeopathology

To date, anthropological comparative studies from Switzerland are rare. Therefore, this research aims to make a comparison between the alpine individuals from Zweisimmen (ca. 14th–19th), and 17 other rural and urban populations from Switzerland all dating to the medieval and early modern period. An osteoarchaeological analysis was carried out on the rural population of Zweisimmen, consisting of 134 skeletons. For each individual, the arm position and orientation were observed in the field, while preservation, representation, sex, age, stature, trauma and pathologies were recorded in the laboratory. These results were compared with data from published and grey literature in order to gain a better understanding of chronological and regional patterns in Switzerland. A chronological development was observed in the orientation, arm position and use of a coffin, which suggests a change in burial practices and beliefs throughout time. The demographic profile represents a natural mortality; however, children and especially neonates are underrepresented in this sample. Some individuals were buried in groups, suggesting simultaneous burial during a period of increased mortality. The palaeopathological findings suggest that the living conditions in rural alpine Zweisimmen were similar to those of other contemporaneous populations, as well as those living in an urban setting.

Bizygomatic breadth determination in damaged skulls

Metric and discriminant function analyses of the skull have been used successfully to determine ancestry and sex from human skeletal remains in both forensic and archaeological contexts. However, skulls are frequently discovered in damaged condition. One structure that is commonly fragmented, even when the rest of the skull is preserved, is the zygomatic arch. The bizygomatic width is an important measurement in craniometry and in forensic facial reconstruction for determining facial width; therefore we propose a simple linear regression model to predict the bizygomatic width of skulls with damaged zygomatic arches. Thirty‐one adult skulls originating from the Indian sub‐continent were used to measure the bizygomatic width. Then, on the same skulls, a straight steel wire was placed at the superior surface of the temporal and zygomatic origins of the zygomatic arch to simulate the zygomatic arch reconstruction on damaged skulls. These wire measurements were used to fit a simple linear regression model between the bizygomatic widths and the wire measurements, and the estimated regression model; Bizygomatic Width (bone) = 0.61 + 1.02(wire measurement), has a very high R2 value of 0.91. Hence, this model could effectively be used to predict bizygomatic widths based on wire measurements. In addition, the bizygomatic widths and wire measurements were collected from 14 New Zealand European skulls to test the ability of the regression model to determine bizygomatic widths from different ethnic groups. This model accurately predicted the bizygomatic widths in New Zealands of European origin skulls and therefore suggests that this regression model could be used for other ethnic groups. The importance of the bizygomatic width for craniometric analysis makes this regression model particularly useful for analysing archaeological samples. Furthermore, this regression line can be used in the field of forensic facial reconstruction to reconstruct damaged zygomatic arches prior to facial reconstructions.

The demographic,socio‐economic and temporal contextualisation of the Universitat Autònoma de Barcelona collection of identified human skeletons (UAB collection)

Identified human skeletal collections are those in which basic demographic data (sex, age and biological origin) are known and are crucial for developing and testing osteological methodologies. It is important that the identified collection be contextualised, and in this way the collection will be considered a reference collection. To contextualise a collection requires documentation of the basic demographic data of the individuals (sex, age, year of birth, geographical area) as well as information concerning the socio‐economic and temporal context in which the individuals lived. The contextualisation of an identified collection is very important so the researchers can understand the ‘point of reference’ when applying a method to it or developing a new method. The purpose of this study is to contextualise the identified skeletal collection of the Universitat Autónoma de Barcelona (UAB) which currently contains 35 adult skeletons of both sexes. To carry out the objectives of the present study, the information about the individuals was collected from cemetery registers and compared with the information of the demographic and statistic public institutions of Spain. The results indicate that the UAB collection is formed only by Spanish nationals who mainly lived during the 20th century in Granollers (Barcelona, Spain). Both sexes are equally represented and all of the individuals are adults. They reflect the most current adult population structure of Catalonia and be treated as a Catalan reference sample of adults living in the 20th century. This collection offers special opportunities for demographic analysis, including validation studies of skeletal ageing and sexing methods that target adult individuals. The collection can also be used in conjunction with other reference samples to investigate secular and populational change in cranial form, sexual dimorphism and stature.
