Examinations of atypical burials can give nuance to the results of larger statistical studies which, by definition, look more at typical practice, and focus more on structure, at the expense of agency. This paper examines six unusual burials of children of the single burial tradition of the Irish later Chalcolithic and Early Bronze Age. In some cases these atypical burials seem to be displaying an emotional response to tragedy, in others they may demonstrate a practical response to unexpected events. One of the burials discussed appears to indicate some form of exhumation and reburial, possibly the result of migration, while another hints at the scale of polities which emerged in the Early Bronze Age. Taken collectively, they add texture to an era about which we know more at a societal level than at the level of the individual.

Only a limited number of genetic diseases are diagnosable in archaeological individuals and none have had causal mutations identified in genome-wide screens. Two individuals from the Gaelic Irish Medieval burial ground of Ballyhanna, Co. Donegal, showed evidence of bone tumours consistent with the autosomal dominant condition multiple osteochondromas. Genome sequencing of the earlier individual uncovered a missense mutation in the second exon of EXT1, a specific lesion that has been identified in several modern patients. The later individual lacked this but displayed a novel frameshift mutation leading to a premature stop codon and loss of function in the same gene. These molecular confirmations of a paleopathological diagnosis within a single rural ancient context are surprisingly disjunct, given the observation of clusters of this disease in modern isolated populations and a de novo mutation rate of only 10%.

Objective This article explores the potential care provided to a middle-aged man who had a suite of injuries evident in his skeleton, most notably an obturator fracture dislocation in his left hip. Materials The skeleton derived from the Late Medieval Gaelic population buried at Ballyhanna, Co. Donegal, Ireland. Methods A transdisciplinary bioarchaeology of care approach was adopted to undertake a phenomenological study of an individual with an acquired disability. Results The man would have required intensive nursing care in the months following the initial injury, and longer-term accommodations may have been made by the wider community to support him. Conclusions Use of a transdisciplinary bioarchaeology of care approach enables important insights to be gained concerning the social impact of disability on the affected individual, his kin, and wider community. Significance This study achieves a new level of integration of bioarchaeological findings with archaeological, historical, and ethno-historical sources, thereby enabling a phenomenological approach to interpretation of life after acquired disability. This is the first study to allow such an intimate insight into lived experience and it provides a model for bioarchaeology of care analysis of individuals from historical eras. Limitations These include difficulties in identifying the nature of a long-standing complex injury. Suggestions for future research Further explorations of the bioarchaeology of care in historical time periods should incorporate a similarly wide range of transdisciplinary sources to enrich interpretations of the lived experiences of individuals, their care-givers and broader communities.

The paper explores the historical and archaeological evidence for maternal and infant death in medieval Ireland. An overview of a range of historical sources including law tracts, medical documents, and folklore are investigated for insights concerning the treatment of pregnant women, abortion, post-mortem caesarean, and the nature of herbs that were administered to assist with female reproductive matters. This provides the context for a review of 15 earlier and later medieval burial grounds in Ireland that produced 30 burials in which an adult female was associated with one or more foetal or perinatal infants. The individuals are considered to have potentially died as a result of obstetric complications. The overall frequency and age-at-death profiles of the women and babies are investigated. This is followed by an attempt to interpret the circumstances of each case to determine whether the death had occurred during pregnancy, childbirth or shortly after birthing.

This study investigates the nature of diet in a predominantly Late Medieval Gaelic Irish skeletal population and explores whether any sex-based and/or age differences were evident in the population. A smaller sub-sample was also examined to determine whether there was any evidence for dietary change over time between the Early Medieval (c.700–c.1200) and Late Medieval periods (c.1200–c.1600). The dietary evidence was derived using a multiproxy approach that combined information from dental palaeopathology (n = 356 adults) and analysis of carbon (δ¹³C) and nitrogen (δ¹⁵N) stable isotope compositions (n = 72 individuals). A higher proportion of females were affected by carious lesions when compared to males. This is possibly suggestive of differing levels of carbohydrate consumption between the sexes, although other factors such as eating habits, and genetic and physiological differences may also have influenced the patterns in the data. The isotopic values indicated that both sexes were consuming similar amounts and types (marine vs. terrestrial) of dietary protein. Elevated δ¹⁵N indicated breastfeeding among the youngest in society but, once children had been weaned, the dietary protein was isotopically similar across the different age categories. Among a smaller radiocarbon-dated sub-sample (n = 37), there was an increase in both the percentage of individuals affected by dental caries and the percentage of teeth affected by dental caries between the Early Medieval and Late Medieval periods. This increase may indicate a greater inclusion of plant-based carbohydrates, such as cereals, in the diet over time, although it may also reflect the younger age distribution of the Early Medieval sample. Interpretations for each of these patterns are discussed with reference to the historical and archaeological evidence. Multiproxy palaeodietary studies for Medieval Ireland are limited and this is the first substantial study of evidence derived from both dental palaeopathology and stable isotope analysis.

The nature and distribution of political power in Europe during the Neolithic era remains poorly understood¹. During this period, many societies began to invest heavily in building monuments, which suggests an increase in social organization. The scale and sophistication of megalithic architecture along the Atlantic seaboard, culminating in the great passage tomb complexes, is particularly impressive². Although co-operative ideology has often been emphasised as a driver of megalith construction¹, the human expenditure required to erect the largest monuments has led some researchers to emphasize hierarchy³—of which the most extreme case is a small elite marshalling the labour of the masses. Here we present evidence that a social stratum of this type was established during the Neolithic period in Ireland. We sampled 44 whole genomes, among which we identify the adult son of a first-degree incestuous union from remains that were discovered within the most elaborate recess of the Newgrange passage tomb. Socially sanctioned matings of this nature are very rare, and are documented almost exclusively among politico-religious elites⁴—specifically within polygynous and patrilineal royal families that are headed by god-kings5,6. We identify relatives of this individual within two other major complexes of passage tombs 150 km to the west of Newgrange, as well as dietary differences and fine-scale haplotypic structure (which is unprecedented in resolution for a prehistoric population) between passage tomb samples and the larger dataset, which together imply hierarchy. This elite emerged against a backdrop of rapid maritime colonization that displaced a unique Mesolithic isolate population, although we also detected rare Irish hunter-gatherer introgression within the Neolithic population.

Unlike other social sciences, the archaeological discipline has been lacking a theoretical framework to discuss the mechanism of migration. Traditionally, patterns of population movements were denoted from material culture and interpreted within the context of ethnicity and the diffusion of ideas without considering underlying processes and incentives, despite active consideration of these issues by geographers and sociologists. It was not until the 1990s that a more integrated archaeological discussion on the various stimuli, influences, and mechanisms of why people choose to migrate was beginning to evolve. Since then, the debate on migration in archaeology has not only reflected on patterns of cultural and technological change but also increasingly on aspects of identity and self-realization; both in terms of how migrants themselves adapt and adjust to their new home environment, and how the host-communities themselves respond and interact with newcomers. Using four case studies, the current paper proposes a new theoretical model for how to assess patterns of group migrations. This new model considers the respective mode of agency related to both the intention and size of the group. “Very High and High Group Agency” represent situations where the migrant group is at a technological and quantitative advantage to the host community, while “Medium and Low Group Agency” represent situations where the newcomers are forced to respond to their new environment through adaptation and adjustment to their local host community.
