History. Philosophy. Sociology. Nonfiction. In this major, highly illustrated, new study Tim Perttula explores the cultural and social landscape of the Caddo Indian peoples (hayaanuh) for about 1000 years between c. 900 and 1900 AD. There were continual changes in the character and extent of ancestral landscapes, through times of plenty, risk, and hardship, as well as in relationships between different communities of Caddo peoples dispersed or concentrated across the landscape at different points in time. These ancestral peoples, in all their diversity of origins, material culture, subsistence, and rituals and religious beliefs, actively created their societies by establishing connected places on the land that became home and lead to the formation of social networks across environments with a diverse mosaic of resources. Established places lent order to the chaotic worlds of people and nature, and they embodied history and the cosmos here on earth. Caddo Landscapes explores the ancestral Caddo constructed landscape, providing detailed information on earthen mounds, specialized non-mound structures, domestic settlements and their key facilities as well as associated gardens and fields, and places where salt, clay, lithic raw materials, and other materials were obtained and the social ties that linked communities in numerous ways. The character and key sequences of ceramics are discussed and radiometric dating evidence provided.
