This study aims to trace status-dependent palaeodietary differences through the bone chemistry of human remains from the site of Imdang, Gyeongsan (the Silla Period). The underlying assumption of stable isotope analysis is that the isotopic composition of bone collagen is expected to be a direct and constant function of diet, where the stable isotope ratios should not decay or change in abundance through time. Carbon and nitrogen stable isotope values were measured from the bone collagen of high status individuals, who are expected to be the ruling class, and individuals from sacrificial burials. These two groups present significant differences not only in their grave goods but also in their dietary components based on stable isotope analysis. High-status individuals have average values of carbon (δ13C = -18.2 ± 0.0‰, n=2) and nitrogen (δ15N = 13.2 ± 0.1‰, n=2) stable isotopes, except for one individual. On the other hand, individuals from sacrificial burials have a wider range of stable isotopic values, and the average values are δ13C = -17.5± 0.7‰ (ranging from -18.7 to -16.2‰), δ15N = 10.0 ± 0.8‰ (ranging from 8.5 to 11.6‰) (n=15). Carbon stable isotopic values for both high and low status groups indicate a largely C3 based diet, where the possible input of C4 consumption cannot be excluded. The carbon isotope results for the individuals from sacrificial burials present relatively enriched δ13C values, which may be attributed to C4 input such as millet. The enriched nitrogen stable isotope values of high status individuals imply the consumption of significant amounts of terrestrial animal protein and possibly marine and freshwater fish in comparison with that of low status individuals.
