RESUMO
OBJECTIVES: Justinian plague and its subsequent outbreaks were major events influencing Early Medieval Europe. One of the affected communities was the population of Saint-Doulchard in France, where plague victim burials were concentrated in a cemetery enclosure ditch. This study aimed to obtain more information about their life-histories using the tools of isotope analysis. MATERIALS AND METHODS: Dietary analysis using carbon and nitrogen isotopes was conducted on 97 individuals buried at Le Pressoir in Saint-Doulchard, with 36 of those originating from the enclosure ditch. This sample set includes all individuals analyzed for plague DNA in a previous study. Mobility analysis using strontium isotope analysis supplements the dietary study, with 47 analyzed humans. The results are supported by a reference sample set of 31 animal specimens for dietary analysis and 9 for mobility analysis. RESULTS: The dietary analysis results showed significantly different dietary behavior in individuals from the ditch burials, with better access to higher quality foods richer in animal protein. 87Sr/86Sr ratios are similar for both studied groups and indicate a shared or similar area of origin. DISCUSSION: The results suggest that the ditch burials contain an urban population from the nearby city of Bourges, which overall had a better diet than the rural population from Saint-Doulchard. It is implied that city's population might have been subjected to high mortality rates during the plague outbreak(s), which led to their interment in nearby rural cemeteries.

The article introduces the enhancements made to the IsoArcH database for isotope paleopathology. This includes the addition of new metadata fields, which allow for describing abnormal anatomical or physiological conditions in humans and animals at either the individual or sample level. To showcase the novel features of the database, the article features a unique dataset of carbon and nitrogen isotope values obtained on bulk bone collagen from 42 clinically-documented cases of the Jedlicka pathological-anatomical reference collection, dating from the 19th century CE and curated at the National Museum in Prague, Czechia. The dataset includes 70 combined isotopic measurements from individuals who underwent anatomizations between 1841 and 1900 and had distinct bone diseases/disorders: i.e. syphilis, rickets, osteosarcoma, osteomyelitis, and healed fractures. Finally, the article highlights the value of the data in helping the isotope bioarchaeology and paleopathology communities in their understanding of disease processes.
RESUMO
In forensic contexts, sternal anatomical varieties represent useful tools for the identification of an individual, either by comparison of ante-mortem and post-mortem data, or by potential comparison of data from biologically related individuals. Sternal body variation is also used to detect the biological affinity of individuals in bioarchaeology. However, no study has been made available to date on the degree to which the overall shape of the sternal body reflects the degree of biological relatedness. We, therefore, analyzed the sternal body shape of 10 individuals with known genealogical data, members of one family over three generations including inbred individuals (19th-20th centuries, Bohemia, Czech Republic), and a control sample of 12 biologically unrelated individuals. First, closely biologically related individuals were compared with unrelated individuals based on 10 variables expressing the morphological characteristics of the sternum, and then all individuals were compared based on Fourier analysis depending on their degree of relationship. The results showed that there is a greater degree of shape similarity in biologically related individuals than in unrelated individuals, and variability decreases with an increasing degree of relatedness. Inbred individuals showed the lowest sternum-shape distances and degree of variability, while unrelated individuals, showed the highest distances and variability. Moreover, in some cases, the documented relationships were also supported by a similar morphology of the ossified and fused xiphoid process. Thus, sternal shape analysis expands the possibilities for individual identification and the detection of the biological affinity of individuals for both the forensic sciences and bioarchaeology.

OBJECTIVES: This study aimed to reconstruct the dietary behavior of two early medieval individuals who display gnathic malformation. MATERIAL: Two skeletons affected by temporomandibular ankylosis were analyzed, one from the Great Moravian burial site of Rajhradice (9th century AD, Czech Republic), and the other from the Avar burial site of SchÓ§nkirchen (8th century AD, Austria). METHODS: Carbon and nitrogen isotopic values were measured from the bone collagen of both individuals. In the Rajhradice case, where the childhood origin of ankylosis is deduced, isotopic analysis of dentine sections was performed. RESULTS: Both individuals show isotopic values within the range of variation of a contemporaneous population sample. There was no observable dietary change in the Rajhradice individual that could be linked to the occurrence of ankylosis. CONCLUSIONS: Both individuals consumed diets typical for their populations. They appear to not have restricted access to foodstuffs, namely animal protein, which would likely have had to be served in liquid (e.g. milk) or in a highly mashed form to compensate for insufficient mastication. SIGNIFICANCE: This finding provides specific evidence of care provided to these two afflicted members of past populations. LIMITATIONS: Though the proportion of animal protein is an important indicator of the quality of diet, many other aspects of diet - such as micronutrient content - elude stable isotope analysis. SUGGESTIONS FOR FURTHER RESEARCH: Amino acid compound specific isotope analyses of collagen would provide deeper insight into both the diet and physiology of the affected individuals.

OBJECTIVES: To highlight conditions that may cause early-onset degenerative joint disease, and to assess the possible impact of such diseases upon everyday life. MATERIAL: Four adults aged under 50 years from a medieval skeletal collection of Prague (Czechia). METHODS: Visual, osteometric, X-ray, and histological examinations, stable isotope analysis of bone collagen. RESULTS: All four individuals showed multiple symmetrical degenerative changes, affecting the majority of joints of the postcranial skeleton. Associated dysplastic deformities were observed in all individuals, including bilateral hip dysplasia (n = 1), flattening of the femoral condyles (n = 3), and substantial deformation of the elbows (n = 3). The diet of the affected individuals differed from the contemporary population sample. CONCLUSIONS: We propose the diagnosis of a mild form of skeletal dysplasia in these four individuals, with multiple epiphyseal dysplasia or type-II collagenopathy linked to premature osteoarthritis as the most probable causes. SIGNIFICANCE: Combining the skeletal findings with information from the medical literature, this paper defines several characteristic traits which may assist with the diagnosis of skeletal dysplasia in the archaeological record. LIMITATIONS: As no genetic analysis was performed to confirm the possible kinship of the individuals, it is not possible to definitively assess whether the individuals suffered from the same hereditary condition or from different forms of skeletal dysplasia. SUGGESTIONS FOR FURTHER RESEARCH: Further studies on premature osteoarthritis in archaeological skeletal series are needed to correct the underrepresentation of these mild forms of dysplasia in past populations.

OBJECTIVES: The aim of this study is to provide a detailed view of dental health in relationship to the diet of the Great Moravian population, with emphasis on childhood diet. DESIGN: We studied skeletal samples of the early medieval population of the Mikulcice agglomeration (Czech Republic) originating from the cemetery of the church VI (91 adults). Stable isotope analysis of carbon and nitrogen (intra-individual sampling - tooth and bone) was performed on this material, and dental characteristics (carious lesions, intensity of caries (I-CE), dental wear, linear enamel hypoplasia) evaluated. RESULTS: Isotopic signals obtained from tooth and bone samples of the same individuals differ significantly. Tooth samples show higher δ13C and lower δ15N than bone samples. δ15N in tooth and bone samples is related to socio-economic status. We discovered a relationship between isotopic signals from tooth or bone and intensity of caries and dental wear. CONCLUSION: We provide the first direct information about the diet of the juvenile part of the Great Moravian population from Mikulcice. The diet of children differed from the diet of adults. Children consumed more millet and less animal protein than adults. The social stratification of this population was obvious in dietary composition from childhood. Elites consumed more animal proteins than non-elite individuals. Tooth decay was related to relative consumption of plant and animal proteins. Greater dental wear is related to a diet based on C3 plants. There was no significant connection between diet composition and the formation of enamel hypoplasia.

OBJECTIVE: This paper aims at investigating the possible existence of isotopic offsets in δ13Ccol and δ15Ncol values in relation to tertiary syphilis. MATERIAL: Based on materials from the 19th c. A.D. deriving from the pathological-anatomical reference collection (the Jedlicka collection) of the National Museum in Prague (Czech Republic), a comparative approach of ten individuals with syphilis and nine without the disease was undertaken. METHODS: Bone powder samples were defatted according to the protocol of Liden et al. (1995). Bone collagen was extracted following the protocol of Bocherens et al. (1991). RESULTS: Our results show that individuals with syphilis have lower δ13Ccol values than individuals without the disease; the observed difference between the two groups is about 0.3-0.4, which is relatively small but still meaningful. However, no difference between δ15Ncol values of the two groups has been noticed. CONCLUSIONS: Either diets prescribed by physicians to syphilitic patients or nutritional stress caused by cyclic appetite disturbance due to the disease itself or the administered medical treatment appeared to be possible explanations of the observed isotopic pattern. Overall, the response of the two isotopic proxies could argue for relatively limited nutritional restrictions. SIGNIFICANCE: This is the first study examining bone collagen isotopic response to syphilis based on clinically documented human skeletal materials. LIMITATIONS: The sample sizes are relatively small and cautiousness must be taken regarding the interpretations of the data. SUGGESTIONS FOR FURTHER RESEARCH: Compound-specific stable isotope investigations and analysis of mercury content could be helpful to better understand the observed isotopic effects.

The aim of this work was to analyse the diet of a Merovingian population sample of 80 individuals buried at Norroy-le-Veneur, France, with regard to their social status and chronology. A carbon and nitrogen stable isotope analysis of human adult bone collagen and related fauna from the same cemetery showed a diet based primarily on C3 plants, supplemented with animal protein in a range comparable to other contemporary sites. No significant contribution of C4 plants (e.g. millet) or marine-derived protein was detected. In terms of socio-economic stratification, individuals buried with rich grave good assemblages formed a narrow group with a significantly higher mean of δ13C than low-ranking individuals. We argue that this may represent a step in the gradual formation of the dietary exclusivity of Frankish elites, following a progressive rise in power of the Merovingian nobility. Also, during the timespan of the cemetery there was a population-wide decrease of 0.3 in the mean value of δ13C. The role of the Christian conversion of the population is questioned, but another factor influencing diet might have played a role.

The exhumation of Danish astronomer Tycho Brahe (1546-1601) was performed in 2010 to verify speculative views on the cause of his death. Previous analyses of skeletal and hair remains recovered from his grave refuted the presumption that he died from poisoning. These studies also outlined the possibility that he actually died from an acute illness, echoing the rather vague and inaccurate testimony of some historical records. We performed a detailed paleopathological analysis of Tycho Brahe's skeletal remains, along with a reconstruction of his diet based on carbon and nitrogen stable isotopes analysis and an estimate of his physical status (relative body fat) based on medullar and cortical dimensions of the femoral shaft. The astronomer's remains exhibit bone changes indicative of diffuse idiopathic skeletal hyperostosis (DISH). The study further allows us to classify him as obese (100% reliability according to our decision tree designed from Danish males), and points out his rich diet (high input of animal protein and/or marine resources) and high social status. Comorbidities of DISH and obesity are reviewed, and their influence on health status is discussed. We further consider some conditions associated with metabolic syndrome as possible causes of Tycho Brahe's final symptoms (urinary retention, renal failure and coma), including diabetes, alcoholic ketoacidosis and benign prostatic hypertrophy. Although a definite and specific diagnosis cannot be established, our study points to today's civilization diseases often associated with DISH and metabolic syndrome as the possible cause of death of Tycho Brahe.

In the Central European context, the 9th and 10th centuries are well known for rapid cultural and societal changes concerning the development of the economic and political structures of states as well as the adoption of Christianity. A bioarchaeological study based on a subadult skeletal series was conducted to tackle the impact of these changes on infant and young child feeding practices and, consequently, their health in both urban and rural populations. Data on growth and frequency of nonspecific stress indicators of a subadult group aged 0-6 years were analyzed. A subsample of 41 individuals was selected for nitrogen and carbon isotope analyses, applying an intra-individual sampling strategy (bone vs. tooth). The isotopic results attest to a mosaic of food behaviors. In the urban sample, some children may have been weaned during their second year of life, while some others may have still been consuming breast milk substantially up to 4-5 years of age. By contrast, data from the rural sample show more homogeneity, with a gradual cessation of breastfeeding starting after the age of 2 years. Several factors are suggested which may have been responsible for applied weaning strategies. There is no evidence that observed weaning strategies affected the level of biological stress which the urban subadult population had to face compared with the rural subadult population.

This study explores differences in stature and their diachronic trends between the urban and rural medieval populations of Bohemia. We estimated stature from the lengths of the long bones of subjects living in Prague (urban) and rural areas of present Czech territory. Our results indicate the absence of significant urban/rural differences in stature in the population living between the 11th and 14th century. For both sexes, the temporal variations in stature in this period show a statistically non-significant decrease in the rural, and increase in the urban, population samples. These findings suggest a uniformity of living conditions in the medieval population in this area of Central Europe. Economic factors causative for urban versus rural stature differences appear later in the Modern Age, probably in relation to industrialization.
