In the sixteenth and seventeenth century, demonological and theological output and controversies over the idea of superstition marked antagonistically the limit of what was Christian, civilized and rational. There are various studies into how the ideas of demons, witchcraft and superstition were projected and exploited in the Christianization of the New World. But to a lesser degree, interpretations can be found that centre on the opposite process: how chronicles, accounts and letters written about the New World contributed to the ideas of early modern superstition. This paper sets out to map which accounts and imaginary of the New World returned and fed the early modern construction of superstition. Such mapping aims to explore this output and identity associations and how they were established. This is a necessary step towards an ‘ecological’ history of modern superstition. Juan Mogrovejo de la CerdaFrançois de La Mothe Considering that superstition (and later ‘divination’ and ‘magic’ as scientific concepts) was the frontier that marked the limit of all kinds of alterities and epistemic teratologies, an ecological history of this would, in a second instance, make it possible to open the possibility of diffracting the line that separates the western Self (Christian and Rational) and the Other (non-western) in order to overcome the potential biases in our current onto-epistemological understandings.
