In this study, 71 human individuals were subjected to stable carbon (δ13C) and nitrogen (δ15N)

isotope analysis of bone collagen samples for the purpose of determining human dietary patterns

in Lithuania during the Late Roman and Migration periods. More specifically, based on the

isotopic data, the aim was to determine and evaluate any potential dietary differences between

individuals on the basis of their sex, age, social status and place of residence during the periods

in question. The results of this study suggest that there were isotopically clearly distinguishable

dietary differences between individuals from different parts/regions of Lithuania. Also, statistically

significant dietary differences (on the basis of δ15N values) between males and females

were observed (although, when making the same sex-based isotopic comparisons at an individual

site level, the same result was observed only among those from Marvelė cemetery). However, no

statistically significant isotopic differences were detected between different social or age groups.

Overall, these results give us one of the first glimpses into the types of dietary habits practiced by

people in various parts of Lithuania during the Roman and Migration periods, which could also

serve as a good starting point for future investigations into other dietary aspects in the territories

and periods in question that still remain unknown.
