Isotopic and Mortuary Variability in a Middle Mississippian Population

Stable-isotopic studies of prehistoric diet have usually confined discussions of isotopic variability within populations to sex-related differences in diet and have rarely considered other social or cultural sources of dietary variation. Extant data from eastern North America suggest that isotopic variation (and hence dietary variation) may have been greatest within the relatively complex Middle Mississippian societies of the late prehistoric period. Correlations between isotopic variability and mortuary variability (an indication of social position) were identified in a sample of burials from the Angel site, a Middle Mississippian (A.D. 1200-1450) civic-ceremonial center in southwestern Indiana. These correlations demonstrate how contextually informed isotopic studies can be used to examine the relations between social position and diet. This approach may be especially useful for studies of social interactions between different populations.
