In Rewriting Maya Religion Garry Sparks examines the earliest religious documents composed by missionaries and native authors in the Americas, including a reconstruction of the first original, explicit Christian theology written in the Americas—the nearly 900-page Theologia Indorum (Theology for [or of] the Indians), initially written in Mayan languages by Friar Domingo de Vico by 1554. Sparks traces how the first Dominican missionaries to the Maya repurposed native religious ideas, myths, and rhetoric in their efforts to translate a Christianity and how, in this wake, K’iche’ Maya elites began to write their own religious texts, like the Popol Vuh. This ethnohistory of religion critically reexamines the role and value of indigenous authority during the early decades of first contact between a Native American people and Christian missionaries. Centered on the specific work of Dominicans among the Highland Maya of Guatemala in the decades prior to the arrival of the Catholic Reformation in the late sixteenth century, the book focuses on the various understandings of religious analyses—Hispano-Catholic and Maya—and their strategic exchanges, reconfigurations, and resistance through competing efforts of religious translation. Sparks historically contextualizes Vico’s theological treatise within both the wider set of early literature in K’iche’an languages and the intellectual shifts between late medieval thought and early modernity, especially the competing theories of language, ethnography, and semiotics in the humanism of Spain and Mesoamerica at the time. Thorough and original, Rewriting Maya Religion serves as an ethnohistorical frame for continued studies on Highland Maya religious symbols, discourse, practices, and logic dating back to the earliest documented evidence. It will be of great significance to scholars of religion, ethnohistory, linguistics, anthropology, and Latin American history.
