This diploma paper provides an overview of the symbols of Christian mysticism within selected poems by Sida Košutić. The theoretical part includes an explanation of the terms "symbol", "mysticism", "Christian mysticism" and a presentation of the symbols of Christian mysticism with their meaning. Bibliographic and scientific data from previous research on the author's works are also presented. The theoretical part about the symbols of Christian mysticism is concretized in the examples of selected poems where the main ideas that run through this stylistic figure are the mystery of the afterlife, transience, eternity and connection of the human being with the supernatural being, ie God. Given the author's choice of such a theme, it was often misplaced in Catholic literature with a religious tendency in its works, so this paper emphasizes that Catholic inspiration does not mean that it is also Catholic literature, but it is in itself aesthetically and artistically valuable. The expression in the author's poems is original and hermetic, and she writes about Christian mysticism as the most real phenomenon.
