Funded by the John Templeton Foundation, the ‘Invisible Dead’ project (Durham University) is exploring diachronic changes in mortuary practices across two regions: Britain and the Levant. In doing so, it uses archaeology as a way to approach fundamental questions about the human condition. This paper explores the principal difficulties faced during the construction of a database for this project and their wider relevance for the development of robust and successful methods for the study of large “mortuary” datasets in the future. It discusses the issues and biases identified within the mortuary record and how the project has sought to mitigate some of these. By adopting a flexible and ultimately expandable approach to data entry and analysis, value can be added to legacy datasets and “grey” literature, allowing us to make comparisons between regions which are both geographically and chronologically distinct.

Using collagen from high-resolution dentine sections of teeth, which form in the perinatal period we investigate the relationship between diet and physiology in this pivotal stage of life. Materials and Methods: Childhood dentine collagen δ13C and δ15N profiles were produced from horizontal sections of permanent and deciduous teeth following the direction of development. These were from two 19th-century sites (n = 24) and a small number (n = 5) of prehistoric samples from Great Britain and Ireland. Results: These high-resolution data exhibit marked differences between those who survived childhood and those who did not, the former varying little and the latter fluctuating widely. Discussion: Breastfeeding and weaning behavior have a significant impact on the morbidity and mortality of infants and the adults they become. In the absence of documentary evidence, archaeological studies of bone collagen of adults and juveniles have been used to infer the prevalence and duration of breastfeeding. These interpretations rely on certain assumptions about the relationship between isotope ratios in the bone collagen of the adult females and the infants who have died. The data from this study suggest a more complex situation than previously proposed and the potential for a new approach to the study of maternal and infant health in past populations.

The British Iron Age site at Glastonbury Lake Village in Somerset is well known for the extensive and prolonged excavations, the comprehensive publications and the superb preservation of organic remains. The environmental material recovered has led to detailed discussion about the nature of the inhabitants' diet. In particular, the recovery of fish and bird bone has led to speculation about the consumption of foods from the wetlands. Previous carbon and nitrogen isotopic analysis of British Iron Age skeletal material has failed to detect significant levels of aquatic resources in the diet during this period, even where sites are located directly on the coast or close to river systems. There is also very little archaeological evidence to suggest that fishing was a major subsistence strategy. The isotopic analysis of skeletal material from Glastonbury Lake Village was undertaken with the hypothesis that if aquatic resources were to be found at significant levels in the diet of a British Iron Age community, this was a site which might reveal it. The results suggest that such consumption is not visible isotopically and was negligible.

The data indicate a human diet which was high in animal protein, with no evidence for any significant marine food input. No differences were found between high-status vehicle (or ‘chariot’) burials and the rest of the population and no other status differentiations are visible according to burial rite, age or sex groupings, although the data obtained for the older males display an unusual trend. No dietary variation is seen between two site phases and no evidence for an early immigrant group is present. The range of isotope values for the adult human group as a whole is small, indicating that the diet is likely to have been consistent over time and across the population, although two individuals stand out as unusual amongst the 62 analysed.
