Much of the work that has been devoted to Latin American history of science, as well as the analysis of intersections between literature and science in the long nineteenth century, points toward the flawed relationship that this region has had with science and technology. Science encompassed a series of proposals of new ways of seeing; it was a new platform that allowed writers to assume and retain control of their environment. This chapter explores the emergence of popular science magazines in Latin America – publications in which, it is argued, we find literary accounts of science as well as creative accounts of scientific observation. An improved understanding of this vast body of work helps us, in turn, to think of fin-de-siècle Latin American science as representative of what Bruno Latour defines as the “exegesis,” or constant inscription, that represents the central quality and activity of modern scientific life.
