A short essay of mine was just published in Engagement, the blog of the Anthropology and Environment Society. The piece examines the story of Cobra Grande, a massive snake of Amazonian folklore that is implicated in the region’s ever-shifting hydrological landscape. I argue that Cobra Grande is more than just a quaint folk tale, but rather a central Amazonian metaphor that reminds that our surroundings are in constant flux, and that humans are not the only ones responsible for this ongoing transformation.
