The topic of this thesis are the avant-garde elements in Kamov’s prose: the novel The Drained Swamp, farces „Woman“, „Catastrophe“, „Suit“ and „Bedbug“, and the short story „Freedom“. By relying on close reading and comparative analysis, the thesis analyzes the importance of grotesque, irony and innovation in texts of Janko Polić Kamov, an author who published during Modernism, but also announced the Avant-garde in Croatian literature. The first part of thesis provides an overview of theoretical insights about the Avant-garde, and relies on influential studies such as Five Faces of Modernity (Matei Calinescu) and Theory of the Avant-garde (Peter Bürger) combining them with books by Aleksandar Flaker and by Gordana Slabinac, texts that include the research of world literature as well as Croatian examples. Although the Avant-garde tends to renounce traditions, the texts written during that period are based on their background: hence, a brief overview of Modernism and Avant-garde is included in the thesis (key periods for reading Kamov). The thesis also details the author's entire opus. The analytical part of thesis describes Kamov's use of irony and grotesque as well as his textual innovations: novelties noticeable in motives, narration, and treatment of time.
