Excavating a parchmenerie : archaeological correlates of making parchment at the Pictish monastery at Portmahomack, Easter Ross

In this study, period-specific dietary trends, along with socio-economic and religious influences on foods consumed by Pictish and medieval inhabitants from Portmahomack are investigated. Bone collagen from human adults (n=137) and fauna (n=71) were analysed for stable carbon and nitrogen isotope ratios to enable dietary reconstructions of the whole adult skeletal assemblage. Adult mean δ 13 C and δ 15 N values from all periods (6 th to 17 th century) were -19.5‰ ± 1.3‰ and 13.3‰ ± 1.7‰ respectively. A diachronic change in diet between early medieval Pictish lay and monastic communities (periods 1-3) and the later medieval parish layfolk (periods 4-5) was found that suggests changing socio-economic and religious influences, along with age and gender differences in diet that reflect possible divisions in labour and status. Faunal data also reflected a diachronic change in diet, most likely related to a change in animal husbandry practices over time. This is the first large-scale study on the Portmahomack assemblage and presents new isotope data to provide a more comprehensive insight into Pictish and medieval subsistence patterns, along with evidence of how religious and social foci may influence diet over time. Such comprehensive investigations can only be adopted by analysing the whole skeletal assemblage, providing robust faunal baselines and inter-and intra-site comparisons. Most importantly, this significant new evidence fundamentally changes our knowledge of diet and subsistence in medieval Scotland and the potential influences therein.
