This paper examines the definition of comics and the issues of themes and genres in this medium, using the example of Andrija Maurović’s opus. Semiotically, the comic book develops a different type of textuality from the traditional literary text, because, in the process of forming meaning, it simultaneously includes visual and verbal components in its discourse. The selected examples of Maurović’s titles and a thematic-genre overview of the same lead implicitly towards an accepted conclusion of literary theory on the relational character of the genre and on the subversive character of art. Given the complex evolution of comic art, this paper also generally discusses artistic media and forms, including literature, children’s literature, illustrated books, and picturebooks, that have some points of contact with comics.
