This article examines Bolesław Prus's use of futurology and utopia in his short story Phantoms (Widziadła). A closer look at the story's images and their sequence not only gives us an insight into the author's philosophy of history but also reveals a utopian vision which can hardly be squared with the realism of his previous work. Thus ‘Widziadła’, written in 1911, can be seen as an important piece of evidence of a change in the writer's beliefs and worldview. It was at that late stage of his life that Prus, a hard-nosed realist and critic of the Romantics, turned into an impassioned idealist who, disillusioned with the world around him, sought refuge in literature. It was to be, however, a fiction like ‘Widziadła’, looking beyond the conventions of realism, unashamedly eclectic and visionary.
