In Mississippian Culture Heroes, Ritual Regalia, and Sacred Bundles, archaeologists analyze evidence of the religious beliefs and ritual practices of Mississippian people through the lens of indigenous ontologies and material culture. Employing archaeological, ethnographic, and ethnohistoric evidence, the contributors explore the recent emphasis on iconography as an important component for interpreting eastern North America’s ancient past. The research in this volume emphasizes the animistic nature of animals and objects, erasing the false divide between people and other-than-human beings. Drawing on an array of empirical approaches, the contributors demonstrate the importance of understanding beliefs and ritual and the significance of investigating how people in the past practiced religion and ritual by crafting, circulating, using, and ultimately decommissioning material items and spaces, including ceramic effigies, rock art, sacred bundles, shell gorgets, stone figurines, and symbolic weaponry.
