Abstract/Summary

This study utilises multi-isotope approaches to investigate early medieval diet and childhood origins of individuals interred in an unusual group burial from Lothian, Scotland. In 1976, the skeletal remains of nine adults and five infants were unearthed from the infill of a latrine of a bathhouse at the Roman fort at Cramond, Edinburgh. Originally thought to be later medieval (14th/15th century), but recently dated to the 6th century AD, these remains represent a rare opportunity to gain deeper insights into the dietary histories and lifetime mobility of the inhabitants of early medieval south-central Scotland. Bone and teeth from the adults (n=9) were sampled, along with local faunal bone from a range of species (n=12). Long-term dietary trends were explored using stable carbon (δ13C), nitrogen (δ15N) and sulphur (δ 34S) isotope analyses of bone collagen, focusing on inter-individual variability and the potential inclusion of marine protein in the diet. Sulphur (δ 34S) was also utilised as a possible indicator of later-life mobility. Strontium (87Sr/86Sr) and oxygen (δ18OCARB) ratios of tooth enamel were employed to identify potential locals and non-locals, as well as possible locations of childhood origin. No intra-group dietary variability was detected, and the results are similar to other contemporary populations from southern Britain. The sulphur isotope data indicate that all of the individuals likely lived locally in their last few decades of life. However, based on isotopic data from tooth enamel, at least one or perhaps two of the individuals likely spent their childhoods in other locations.
