Limb bones asymmetry and stress in medieval and recent populations of Central Europe

Monitoring the degree of asymmetry in different parts of the human body can contribute to population studies, as it may be connected indirectly with the social structure, living conditions, and also with biomechanical stress affecting the person. Analysis of asymmetry may also assess preferential use of the right or left of the body during specific activities. This study is based on the measurements of bones of the upper and lower limbs of skeletons derived from the remarkable medieval cemeteries of Mikulčice‐Kostelisko (78 male, 132 female) and Prušánky (66 male, 69 female) (9th–12th centuries AD), and a series of skeletons representing a recent population from Bohemia (143 male, 157 female). The objective was to assess directional asymmetry (DA), fluctuating asymmetry (FA) and antisymmetry (AS) of the dimensions of the evaluated bones, and to use these data to compare the characteristics of the medieval and recent populations. DA was recorded in most dimensions. In the upper limb, the humerus exhibited the greatest expression of asymmetry, and, with the exception of the clavicle, DA was always more pronounced on the right side. Conversely, DA was less prevalent in the lower limb bones. It was more pronounced on the transverse, sagittal and circumferential dimensions of the diaphyses and epiphyses than on the length, and in most cases it was on the left side. The FA values were very low, and almost negligible in relation to the size. Nevertheless, FA was markedly more frequent on the lower than on the upper limb. In contrast to the medieval population, the recent population had higher FA and DA values. Thus, we propose that people from this medieval population were subjected to lower developmental stress than the recent sample. Copyright © 2008 John Wiley & Sons, Ltd.     

Modeling skeletal traits and functions of the upper body: Comparing archaeological and anthropological material

The aim of this study is to look at upper body functional modifications caused by mechanical loading. We look at 4th lumbar vertebra as well as fibrous humeral musculoskeletal stress markers (MSMs). This study uses information provided by magnetic resonance images of living individuals from the University of Oulu Hospital data banks (N = 91), archaeological skeletons from Sweden (N = 54) and England (N = 61), and autopsied skeletal collection of early 20th century Finns in Natural History Museum, University of Helsinki (N = 48). The lumbar vertebrae and MSM are subjected to mechanical loading caused by the upper body weight and loads lifted and/or carried. We hypothesized that the vertebral size reflect body size, habitual mechanical loading and the overall skeletal robusticity as mechanical competence to withstand mechanical loading standardized to body size, which has decreased over millennia. For Helsinki material occupation, age and sex is known and the material was used in Niinimäki (2011). In the study by Niinimäki (2011) MSM were found to be affected by the intensity of muscular action as well as body size and age. This study is reviewed here in light of re-analysis of the data to follow the current anatomical understanding of the entheses as well as viewing MSMs as a part of upper body functional complex. Only fibrous entheses were included in the re-analysis. Furthermore, due to small number of females where activity intensity could be assessed, females were dropped from the re-analysis.     

The end of slavery: Disease patterns and cultural behaviours of African Americans in Suriname

There have been few bioanthropological studies related to African Americans, either slaves or free people. The results of an analysis of eight skeletons of African ancestry (five males and three females) acquired in Suriname at the end of the 19th century by Dr J. Spilzley and currently housed in the Duckworth Collection (University of Cambridge) are presented. Dental abrasion related to habitual pipe smoking was observed in four individuals, confirming the widespread use of pipe to smoke tobacco among slaves observed in other related sites. Our results indicate a very poor state of oral health for these individuals, with females presenting a higher frequency of dental carious lesions and antemortem tooth loss in comparison with males. The presence of cribra orbitalia in some individuals suggests, as observed in other diaspora skeletal series, individuals suffering from severe stress, caused by poor nutrition, infectious diseases, or both. Such appalling life conditions agree with many written records, which describe very harsh work conditions and very deprived diets. Our results, although based in a small sample, contribute to a better understanding of the cultural behaviours as well as the patterns of disease that afflicted the African Americans in Suriname in the 19th century.

Enamel hypoplasia in Danish and Lithuanian Late Medieval/Early Modern samples: a possible reflection of child morbidity and mortality patterns

Numerous studies and various interpretations of the prevalence of linear enamel hypoplasias (LEH) based on populations living in different cultural and economic conditions are causing some confusion and raising doubts about whether or not such LEH are reliable indicators of life conditions. An analysis of LEH prevalence patterns was performed on the adults of three populations: Tirup—a Danish Medieval rural population of the 12–14th centuries (131 individuals), Subačiaus str. in Vilnius—a Lithuanian Late Medieval urban population of the 16–17th centuries (88 individuals), and the aristocracy—a Lithuanian pooled sample population from several churches of the 15–18th centuries (66 individuals). Statistical testing of the influence of population affinity, sex and age at death was also performed. Since the same investigator scored all the samples, possible inter‐observer error bias was minimized. In all the populations, LEH formation ages were similar. Statistically significant sex differences were found only in the aristocratic sample (with higher male frequency). It was found that the town population was characterized by the highest frequency of affected individuals, with the highest severity and highest number of stress episodes per individual. A reliable relationship with age at death was found only in the town sample: individuals with more numerous and more marked LEH had shorter life expectancies in adulthood. Different “most vulnerable years” for subsequent life expectancies were noted for different populations. A tentative explanation of these differences could be the pooled effect of differential morbidity and mortality. It seems that the rural population experienced the highest morbidity and nutrition deficiency as well as the highest child mortality whereas, in the urban sample, high morbidity was accompanied by a lower child mortality. Both lower morbidity and mortality seem to be characteristic for the aristocracy. Copyright © 2002 John Wiley & Sons, Ltd.     

Interpreting diachronic osteological variation at the medieval necropolis of the Sant Pere Churches (Terrassa,Spain)

The purpose of this study is to analyse the diachronic variation in the skeletal sample exhumed from the medieval necropolis of Sant Pere Churches, interpreting the results using the archaeological and historical evidence. The Sant Pere Churches are a monumental Romanic complex located in Terrassa (Spain) and built over the earlier Episcopal Cathedral of Egara from the Visigoth period. Egara has traditionally been considered the precursor of the current city of Terrassa; however this name disappeared from historical documentary sources after the period of Muslim incursions into Hispania (8th century). An archaeological excavation undertaken recently at the Sant Pere Churches provided us with the opportunity to study the population that was interred in this complex during that epoch. In total, the skeletal remains of 208 individuals were examined. In order to analyse the diachronic variation, the sample was divided into two periods, that of the Cathedral of Egara (4th–8th centuries; N = 128) and that of the Parish Churches of Terrassa (9th–13th centuries; N = 80). Both periods of the complex exhibited a similar skeletal age distribution, including under‐representation of non‐adult individuals. Nevertheless, a bias towards males in terms of sex distribution, sex differences in the mortality level and greater sexual dimorphism were observed in the population interred at the Cathedral of Egara. Moreover, analysis of the prevalence of skeletal disorders also provided evidence of higher differences between sexes for the period of the Episcopal Cathedral of Egara, the female population exhibiting the lower prevalence. Additionally, diachronic variation in both postcranial and dental disease patterns was observed, suggesting different activity patterns and food consumption between the periods. Overall, the results suggested that diachronic osteological variation observed in the Sant Pere Churches skeletal sample was most probably linked with the changes in the role of the complex following the Muslim incursion of the 8th century.

Changing Notions of Authenticity: Presenting a Castle Over Four Centuries

Bolsover Castle is a 17th‐century mock‐medieval castle built for the Cavendish family. First impressions suggest that its Pillar Parlour has survived with little alteration for nearly four centuries. In reality, there have been minor but telling changes to its fabric. The 18‐century Cavendishes venerated the castle as a shrine to their ancestors. Bolsover’s 19th‐century tenants recreated a romantic Olden Time appearance. The public bodies responsible for the castle in the 20th century used archaeology to reconstruct its 17th‐century form. In each case, these custodians aimed to present the site ‘authentically’, but their work reveals their own contemporary readings of the castle’s history. This evidence, gathered for a Conservation Plan, allowed English Heritage’s re‐display of the castle (1996–2001) to take a more reflective and positive approach to creating new meanings. This use of history to create local important meanings should give good cheer to those managing similar small but significant sites across the world.     

Potential osteoarchaeological evidence for riding and the military use of horses at Malbork Castle,Poland

The paper explores interpretations of two sets of pathological horse vertebrae identified during analyses of animal bones from recent excavations at the castle at Malbork in northern Poland (formerly Marienburg in Prussia). One specimen dates to the 18th century and the other to the medieval period. The castle was initially constructed by the Teutonic Order from the late 13th century and occupied by military institutions into the 19th century, and is one of the largest fortified structures in Europe. The pathological vertebrae are attributed to prolonged load‐bearing. The problematic interpretation of the remains from the medieval context as belonging to a warhorse is discussed. Warhorses are widely described in contemporary documentary sources which indicate that mares were typically kept in farms on the Order's estates in late‐medieval Prussia, while studs were separately stabled at castles. There is not enough data to confirm the medieval specimen as a warhorse, and both vertebrae may simply represent riding animals. Copyright © 2009 John Wiley & Sons, Ltd.     

Detecting the environmental impact of the Baltic Crusades on a late-medieval (13th–15th century) frontier landscape: palynological analysis from Malbork Castle and hinterland,Northern Poland

Palaeoecological analysis of peat deposits from a small bog, combined with pollen analysis of sediments infilling the moat of the nearby Teutonic Order castle at Malbork, have been used to examine the ecological impact of the Crusades on the late-medieval landscape of Northern Poland. Studies of the environmental impact of the Crusades have been almost exclusively informed by written sources; this study is the first of its type to directly investigate the environmental context of Crusading as a force of ecological transformation on the late-medieval Baltic landscape. The pollen evidence from Malbork Castle and its hinterland demonstrate that the 12th/13th–15th centuries coincide with a marked transformation in vegetation and land-use, characterized by clearance of broadleaved woodland and subsequent agricultural intensification, particularly during the 14th/15th centuries. These changes are ascribed to landscape transformations associated with the Teutonic Order’s control of the landscape from the mid-13th century. Human activity identified in the pollen record prior to this is argued to reflect the activities of Pomeranian settlers in the area. This paper also discusses the broader palaeoecological evidence for medieval landscape change across Northern Poland.     

Late-Medieval Horse Remains at Cēsis Castle,Latvia, and the Teutonic Order’s Equestrian Resources in Livonia

EXCAVATIONS AT the castle complex of Cēsis, Latvia, uncovered an unusual find of large quantities of horse bones, some of which were partially articulated, along with equestrian equipment. These were associated with a destroyed building at the edge of the southern outer bailey. The horses included large males, most probably stallions, and pathology on several of the recovered vertebrae suggests these individuals had been used for riding. The size of the horses was within the range for medieval war horses, and the associated tack also pointed to prestigious riding animals. Radiocarbon dating of the bones placed them firmly within the Teutonic Order's period of rule. We conclude here that these horses fulfilled a military role in the final decades of the Teutonic Order’s rule in Livonia in the late 15th/early 16th century and that the better-known equestrian culture of late-medieval Prussia was comparable in character, if not in scale, to that in Livonia.     

Further aspects of fur trade life depicted in the skeleton

Osteobiographies were reconstructed from the skeletal remains of four adults from Fort Edmonton, a 19th century trading post of the Canadian fur trade. Three males were Caucasoid and probably ethnic Scots, given the usual origin of fur traders in this region. The lone adult female in the sample was Mongoloid, either Indian or Métis, and likely the ‘country wife’ of a fur trader, since she was buried in the European tradition in the fort cemetery. The cause of death is not discernible from any of the skeletal remains and none of these individuals exhibit any evidence of chronic infectious disease, malnutrition or neoplasia. Trauma, arthritis and other indicators of physical stress do appear, however, and present an opportunity to expand our understanding of the effects of fur trade life on the skeleton. Viewed in the context of historical accounts of life at the fort in the early 19th century, stress markers on the skeletons of three males have led to the conclusion that they were voyageurs who engaged in trading trips by canoe or boat. Lesions of the capsule attachment area at the proximal tibio‐fibular articulation appear unilaterally in two males and may be associated with ‘mushing’ or driving a dog sled in winter. The musculoskeletal lesions on the one preserved female skeleton are consistent with the arduous domestic activities documented at the fort, which include milking cows, churning butter, stirring lye soap, and harvesting grain and root vegetables by hand. Since specific occupations or behaviours cannot be precisely determined from muscular attachment and other stress markers, these interpretations are made cautiously and only in the culture‐historical context of the skeletal sample.

Non‐specific indicators of stress and their association with age at death in Medieval York: Using stature and vertebral neural canal size to examine the effects of stress occurring during different periods of development

Selective mortality can occur towards individuals who survive episodes of physiological stress, such as disease and malnutrition, during development. The skeletal elements affected depend on the timing of these stressful episodes. Studying multiple non‐specific indicators of stress can show which periods of development were affected and whether certain periods can be linked with selective mortality. To examine this method a preliminary study of 61 adult individuals from the Medieval population of Fishergate House, York was undertaken to examine small vertebral neural canal size and reduced adult stature. Previous studies have shown that selective mortality occurs towards individuals who display these non‐specific indicators of stress. Statistical analysis showed that small transverse neural canal diameter was significantly associated with early adult mortality for males and females and there was evidence of selective mortality towards females with reduced stature. This suggests that individuals who died in early adulthood experienced health insults during late childhood which stunted VNC growth but males in particular were not significantly affected by health insults after this age as they achieved a normal adult stature. Therefore it appears that health insults which occurred during late childhood had a greater influence on adult health in the Fishergate House population. This method could be expanded to provide more detailed information by using a greater variety of non‐specific indicators of stress which will allow more specific periods of development to be investigated.

Trauma and amputations in 19th century miners from Kimberley,South Africa

Trauma is the result of violent accidental or therapeutic events that cause physical or psychological injury. The frequencies and types of trauma within a population can give important information regarding their lifestyle as well as the quantity and quality of medical care available to them. The purpose of this study was to assess the incidence of trauma in the Gladstone sample population with regards to the presence of interpersonal violence a hazardous working environment strenuous working requirements and the availability of medical care. The individuals studied here were diamond miners from Kimberley dating to the late 19th century. A total of 107 well‐preserved skeletons were excavated from unmarked graves after accidental discovery. This sample included 86 males 15 females and 6 individuals of unknown sex. The majority of individuals (71%) were between 19 and 45 years of age. The remains were most likely those of migrant mine workers of low socioeconomic status who had passed away at the local hospitals. All bones were visually assessed for macroscopic indications of traumatic bone alterations and compared to standard palaeopathological texts and photographs. A total of 27% (n = 28) of the individuals in the sample presented with well‐healed healing or perimortem fractures. Fractures to the skull encompassed 49% (n = 20) of all the fractures that were observed. A total of six (6%) amputations were noted. Spondylolysis was observed in 7% (n = 7) of the individuals within the sample and longstanding subluxation was noted in two individuals. The high incidences of cranial fractures within this population are suggestive of high levels of interpersonal violence while long bone fractures spondylolysis and evidence of longstanding subluxations are indicative of the strenuous work requirements and the high‐risk environment to which these individuals were exposed. When considering the presence of well‐reduced fractures and healed amputations it seems that adequate medical care was available to at least some members of this community.

Evidence for “Celtic migrations”? Strontium isotope analysis at the early La Tène (LT B) cemeteries of Nebringen (Germany) and Monte Bibele (Italy)

Strontium isotope analysis on human remains from the Iron Age (4th/3rd century BC) cemeteries of Nebringen, Germany and Monte Bibele, Italy were carried out to investigate the role of residential changes during the period of the historic “Celtic migrations”. From an archaeological perspective, the location of the cemeteries in the Celtic core (Nebringen) and expansion area (Monte Bibele), and the distinctive development of their material culture, suggest that the buried populations had differing mobility rates. On the contrary, the strontium results indicate that only few individuals were mobile or non-local. There is, however, a difference in variation of strontium isotope ratios between the two studied cemeteries, presumably caused by differing geological conditions. In Nebringen changing use of cultivated land in a geologically heterogeneous environment most likely caused varying strontium isotope ratios even within the same jaw, while individual mobility over longer distances can also not be excluded. In Monte Bibele the range of strontium isotope ratios is narrow, and this may be explained by a community living in the same village and using the same agricultural resources. For various prehistoric time periods it has been suggested that some population groups were more mobile than others, for example because they had special social roles. In the two cemeteries studied here, males have slightly more often a non-local birthplace or moved during childhood. In contrast, females had isotope signatures which are more consistent with the local geological environment. Male mobility is, however, not correlated with burial as a warrior, and patrilocal residential patterns were not observed among females. Foreign and local items are found with isotopically local and non-local individuals and objects per se do not indicate descent. The motives for residential changes were, therefore, varied and not constrained to a specific area or population group. The presented dataset provides details on the way of life and land-use in the Celtic communities, for which information is otherwise absent.     

The Siting of Medieval Castles and the Influence of Ancient Places

THIS PAPER EXAMINES the ways in which the siting of castles in England was influenced by the remains of monuments and landscapes from the prehistoric and Romano-British periods. It explores the character, distribution and scale of ancient monument reuse as evidenced through the archaeological and documentary record, in an attempt to discern patterns in peoples’ responses to monuments from the ancient past. It considers the ways in which these places were perceived by both the ruling elite and the local community: exploring how inherited landscapes were used in castle building to structure concepts of belonging, constituted through memory and genealogy. The conclusion is that ancient places were reused by castle builders from the 11th to the 14th century as part of an evolving narrative aimed at enhancing rights to people, place and power.     

Life on the Edge of the Arctic: The Bioarchaeology of the Keldudalur Cemetery in Skagafjörður,Iceland

Burials were examined from the late Viking Age early medieval Christian cemetery at the farm of Keldudalur in the Skagafjörður region, Northern Iceland. The cemetery likely served a single household for about 100–120 years, from the beginning of the 11th century AD to the turn of the 12th century. Cemetery inhabitants represent a population that lived through the transitional period when Christianity was established in Iceland. The changes are visible in the mortuary record with the changeover from outlying pagan graves to enclosed Christian cemeteries situated on the farmsteads. Keldudalur is one of the numerous early Christian family cemeteries that littered the 11th century Skagafjörður landscape. The burials included 53 well‐preserved skeletons of 27 adults and 26 subadults. Various factors such as fluctuating climate and environmental conditions, and seasonal or periodical availability of resources have the potential for impacting human diet and health over time. To assess the health status of the burials, data were collected for a number of health status indicators such as stature estimation, developmental enamel defects, porotic hyperostosis, infectious disease, trauma, degenerative joint diseases, dental caries, calculus and tooth loss. Results suggest that inhabitants of Keldudalur experienced periodic stress and rigorous living conditions. Infant mortality was great, although if individuals survived childhood, the age expectancy was fairly high. There was no obvious evidence for interpersonal violence or endemic infectious disease. However, the common occurrence of growth disturbances, generalised periostitis, trauma and degenerative joint disease all point to a number of stressors in the lives of the people at Keldudalur, which is suggestive of a resilient people living and adapting to a harsh and periodically resource scarce subarctic environment.

Evidence of the crested form of domestic hen (Gallus gallus f. domestica) from three post-medieval sites in Hungary

In this paper, the authors introduce finds of crested hen from three post-medieval Ottoman Period (16th–17th century) sites in Hungary. All the remains were found in Buda, the former capital of Hungary. Two sites are located within the castle area, while the third lies south of the royal palace. Since the animal bone assemblages yielding the skulls of crested hen under study showed Ottoman Turkish influence and the castle of Buda was a high status area, it is likely that crested hen represents one of the newly introduced breeds of domestic animals that arrived to Hungary with people of Balkan origins.     

The Relationship Between Linear Enamel Hypoplasia and Social Status in 18th to 19th Century Edo,Japan

Linear enamel hypoplasia (LEH) has been utilised in human bioarchaeology as an indicator of growth disturbance during childhood. However, only a few studies have compared populations of different socio‐economic status in the same time period. This study examines the association between the LEH occurrence pattern and social status in the 18th to 19th century populations in Japan. Detailed archaeological studies on burials from the Edo period (1603–1867) excavated in Tokyo have facilitated estimating an individual's social status by its burial type. In this study, 112 individuals from the Sugenji‐Shokenji site were divided into three burial structure groups (ceramic jar coffins for middle‐class warriors, wooden square coffins for low‐class warriors and townspeople and wooden circular coffins for townspeople) and examined for the general prevalence of LEH, number of LEH and the chronological distribution of LEH. A high general prevalence of LEH was observed in every group, especially in lower canine (79.3–100.0%). However, individuals in the jar coffin group showed a lower prevalence and smaller number of LEH per tooth, suggesting that individuals of higher social status experienced better living environments in their childhood. There was no significant difference in the chronological distribution of LEH formation between coffin groups. Such data are essential for understanding the association between socio‐economic status and living conditions in specific societies in the past. Copyright © 2015 John Wiley & Sons, Ltd.     

Severe lead contamination among children of samurai families in Edo period Japan

This paper presents evidence for severe lead contamination among children of samurai families living in a castle town in Edo period Japan (1603–1867). Excavated rib bones were analyzed by atomic absorption, and soft X-ray roentgenograms of long bones were taken. The median values of lead concentration in the bones of children 3 years of age and under(1241.0 μg Pb/g dry bone) and 4–6 years of age (462.5 μg Pb/g dry bone) were significantly higher than those of adult males (14.3 μg Pb/g dry bone) and females (23.6 μg Pb/g dry bone) (p < 0.001). In addition, that of children over 6 years of age (313.0 μg Pb/g dry bone) was significantly higher than those of adult males (p < 0.01) and adult females (p < 0.05). The median value of lead in the bones of children 3 years of age and under was over fifty times higher than that of their mothers (adult females). Hypertrophy was seen in the long bones of five samurai children. In this area, lead lines or lead bands were distinguished by soft X-ray roentgenogram. Samurai children suffered from severe lead contamination in Edo period Japan. When the mothers were nursing their children, the children might have ingested their mother’s white lead non-selectively.     

Distribution of dental caries in an early 17th century swedish population with special reference to diet

The distribution of dental caries was determined in complete and partial human dentitions from a 17th century (1621–1640) city graveyard excavated in Gothenburg, Sweden. Sixty‐three adults and two children, divided into five different age groups, were studied. Altogether 949 teeth (943 permanent and six deciduous) were examined macroscopically using a dental probe and X‐rays. A high number of teeth had been lost post‐mortem. An increase in ante‐mortem tooth loss was found with increasing age. Sixty per cent of all individuals and 12% of all teeth showed signs of caries. The number of carious teeth per subject increased with increasing age. The highest prevalence of individuals with caries was found for the age group 26–35 (69%). Caries were most prevalent in the first, second and third lower molars (60%), while the incisors and canines in the upper and lower jaws were the least affected teeth (1%). The occlusal surface was the area most susceptible to caries (45%), followed by the buccal cemento–enamel junction (16%) and the approximal contact point (11%). This study shows that, although consuming a diet believed to have been lower in sugar content compared to modern populations, caries did affect a rather high number of individuals living in Sweden during the early 17th century.
