Drawing on Hubert Zapf’s view of literature as cultural-ecological potential and its manifestation in three functions (critical metadiscourse, imaginative counterdiscourse, and reintegrative interdiscourse), the author of this article offers a new interpretation of Vytautas Petkevičius’s children’s book Didysis medžiotojas Mikas Pupkas (The Great Hunter Mikas Pupkus, 1969). She also refers to a Norwegian theoretical model according to which it is possible to identify a subject’s relationship to nature and to localize it within a system of coordinates – an axis of meaning based on the oppositions nature worship/problematization of nature and anthropocentric horizon/biocentric horizon. Mitunevičiūtė argues that, even though it might have served the critical metadiscursive function, the potential encoded in this parody of hunting and exposure of the hunter’s image remains unexploited. While Petkevičius posits “humane” hunting as a possible means of regulating the balance of nature and suggests its complete denial, he does not carry this project to the end. The devastation of nature in the land of Nylon and the glaring consequences of ecological catastrophe represented in the work fulfill the function of representative antidiscourse. As an effective ecopedagogical tool capable of shaping young readers’ thinking, worldviews, and emotional and cognitive understanding, and of integrating ecological ideas into their cognitive field, Didysis medžiotojas Mikas Pupkus serves a reintegrative interdiscursive function. The author of the article argues that this function also has a broader application: while the work appeared in an era that was not conducive to the expression of ecological thinking, it became a vehicle for the expression of ecological ideas, helping to integrate them into the broader cultural field. The article focuses on how the subject’s relationship to nature changes depending on the work’s shifting intonations, and on how the subject acts in the world represented. With the movement from anthropocentrism to biocentrism within the general space of the work, this relationship remains ambiguous.
