Flying velocipedes, scent claviers, surviving on pills. These are some of the novelties in what has been heralded as the first Swedish science fiction novel: Oxygen och Aromasia: Bilder från år 2378 (Oxygene and Aromasia: Pictures from the Year 2378), written by the cosmopolitan liberal writer and publicist Claës Lundin (1825–1908) and published in 1878. This chapter discusses Oxygen and Aromasia by relating the novel to other works by Lundin and situating it in a political and cultural context. In his writings, Lundin placed science and technology as well as liberal reforms at the centre of society's journey into the future. Departing from the interdisciplinary field Critical Future Studies, this chapter analyses how Lundin's novel is “opening up or closing down imaginative possibilities” (Godhe & Goode 2018). What kind of people are supposed to live in Lundin's futural fictive landscape? By deconstructing the novel Oxygen och Aromasia and emphasising the cracks in the narrative, this chapter shows that Lundin's usual progressiveness (in his other writings) is more ambivalent in this tale. At the same time, it asks questions concerning how his novel both widens the scope of possible futures and shuts down imaginative possibilities.
