Before European settlers arrived in North America, more than 300 distinct languages were being spoken among the continent's Indigenous peoples. But the Euro-American emphasis on alphabetic literacy has historically hidden the power and influence of Indigenous verbal and nonverbal language diversity on encounters between Indigenous North Americans and settlers. In this pathbreaking work, Phillip H. Round reveals how Native North Americans sparked a communications revolution in their adaptation and resistance to settlers' modes of speaking and writing. Round especially focuses on communication through inscription—the physical act of making a mark, the tools involved, and the social and cultural processes that render the mark legible. Using methods from history, literary studies, media studies, linguistics, and material culture studies, Round shows how Indigenous graphic practices embodied Native epistemologies while fostering linguistic innovation. Round's broad theory of graphogenesis—creating meaningful inscription—leads to new insights for both the past and present of Indigenous expression in a range of forms. Readers will find powerful new insights into Indigenous languages and linguistic practices, with important implications not just for scholars but for those working to support ongoing Native American self-determination.
