Item Diet, economy, and culinary practices at the height of precolonial Swahili urbanism(Elsevier, 2022) Quintana Morales, Eréndira M.; Craig, Oliver E.; Prendergast, Mary E.; Walshaw, Sarah; Cartaciano, Christina; Mwebi, Ogeto; Nguta, Esther; Onduso, Veronicah; Fleisher, Jeffrey; Wynne-Jones, StephanieSwahili cuisine is known across Africa and globally as a highly distinctive product of a cosmopolitan, coastal, urban society. Here we present a comprehensive study of precolonial Swahili diet and culinary practices at the coastal town of Songo Mnara, positioning archaeological and ethnographic understandings of cuisine in a long-term coastal tradition. We explore contemporary food cultures and then present the first direct evidence for precolonial cuisine by combining ceramic lipid residue analysis with archaeobotanical, zooarchaeological, and faunal and human stable isotopic data. Integrating these datasets produces a detailed picture of diet at the site of Songo Mnara during the peak of precolonial Swahili urbanism. Lipid residue analysis demonstrates how plant and animal products were consumed and valued in ways not discernible from plant and animal remains alone. We also note special treatment for particular foodstuffs, including an association of fish consumption with high-status spaces and vessels, and preferential management of cattle for milk. A more complex picture of urban life emerges, recognizing influences of taste, class, and culture. Our findings demonstrate the potential of multi-layered anthropological studies for exploring cuisine and urban life in coastal contexts across the globe.Item Reconstructing Asian faunal introductions to eastern Africa from multi-proxy biomolecular and archaeological datasets(Public Library of Science, 2017) Prendergast, Mary E.; Buckley, Michael; Crowther, Alison; Frantz, Laurent; Eager, Heidi; Lebrasseur, Ophélie; Hutterer, Rainer; Hulme-Beaman, Ardern; Van Neer, Wim; Douka, Katerina; Veall, Margaret-Ashley; Morales, Eriéndira M. Quintana; Schuenemann, Verena J.; Reiter, Ella; Allen, Richard; Dimopoulos, Evangelos A.; Helm, Richard M.; Shipton, Ceri; Mwebi, Ogeto; Denys, Christiane; Horton, Mark; Wynne-Jones, Stephanie; Fleisher, Jeffrey; Radimilahy, Chantal; Wright, Henry; Searle, Jeremy B.; Krause, Johannes; Larson, Greger; Boivin, Nicole L.Human-mediated biological exchange has had global social and ecological impacts. In sub-Saharan Africa, several domestic and commensal animals were introduced from Asia in the pre-modern period; however, the timing and nature of these introductions remain contentious. One model supports introduction to the eastern African coast after the mid-first millennium CE, while another posits introduction dating back to 3000 BCE. These distinct scenarios have implications for understanding the emergence of long-distance maritime connectivity, and the ecological and economic impacts of introduced species. Resolution of this longstanding debate requires new efforts, given the lack of well-dated fauna from high-precision excavations, and ambiguous osteomorphological identifications. We analysed faunal remains from 22 eastern African sites spanning a wide geographic and chronological range, and applied biomolecular techniques to confirm identifications of two Asian taxa: domestic chicken (Gallus gallus) and black rat (Rattus rattus). Our approach included ancient DNA (aDNA) analysis aided by BLAST-based bioinformatics, Zooarchaeology by Mass Spectrometry (ZooMS) collagen fingerprinting, and direct AMS (accelerator mass spectrometry) radiocarbon dating. Our results support a late, mid-first millennium CE introduction of these species. We discuss the implications of our findings for models of biological exchange, and emphasize the applicability of our approach to tropical areas with poor bone preservation.
