The year 1926 is a milestone for Argentine literature as it marked the publication of three books which represented a radical innovation for narrative prose: the novels Don Segundo Sombra, by Ricardo Güiraldes, and El juguete rabioso (The Mad Toy) by Roberto Arlt; and Horacio Quiroga’s Los desterrados (The Exiles), a short-story collection. These three books can be seen as a reconfiguration of a literature that, since its origins, had space as its privileged protagonist. Güiraldes’ novel postulates an idealized image of the countryside that, in the third decade of the twentieth century, was consciously anachronistic and nostalgic. In Arlt’s novel, the modern city is a symbol of novelty and even of the future, and also a constant source of irresolvable conflicts. In turn, the stories from Los desterrados, which take place in the frontier territory of Misiones, updated the fictional possibilities of the border understood as a contact zone. The publication of these three books in 1926, then, implied a renewal of the spaces privileged by Argentine literature: the countryside, the city, and the border. In addition, they are testimony to how the 1920s marked a definitive change in the ways of being a writer.
