This paper is about Šimunović’s novel Duga which we have analysed from the gender theory point of view. Firsty, we have presented the summary of literary work of Dinko Šimunović which is mostly permeated with patriarchal aspect, taking in considerations that the writer himself comes from that kind of environment. Based on his novel Duga we have analseyd the character of Srna/Brunhilda who presents danger for the society where she lives because she doesn’t behave the wy she should in the precisely defined patriarchal rules. While captured in socialy-cultural conventions, craving for freedom, she decides to change her gender by walking under the rainbow because she knows that only as a male colud she fulfill her aspirations. With the motive of the rainbow and the folklore which shows that by walking under the rainbow a female becomes a male, Šimunović highlights the thing that stretches further on in his work – the importance of the folk customs, tradition and folk elements. Secondly, we have written about feminism, its first beginnings and the representations of the feminist theories. We have emphasized a few important views and endless questions that have been asked about power relations, position of women both in cultural, political and literary aspect. Finally, we have described gender issue in Šimunović’s prose where he, through his main characters, shows how an individual hardly copes with general social conventions. Dinko Šimunović was a writer who brought a lot of autobiographical elements, always between reality and imagination he thought that people are not able to see a bigger picture of the world and they don’t understand the problems he writes about. Although he showed up in literature at the very beginning of the 20th century in the time of many modernistic flows, he had always stayed faithful to tradition and caring for his own literature, because only if aware of your own can we understand the other.
