The thesis is devoted to the following two representatives of literal decadence, Oscar Wilde, British dramatist, prose writer, poet and essayist, and Arthur Breisky, Czech prose writer, literary critic and translator. The thesis opens with providing a basic insight into the life and work of both authors. They were both influenced by decadence, which was not only an artistic trend, but also a specific spirit of the time that was reflected in the psychological and social roots and opinions of both authors. The thesis works with the basic assumption that the Czech decadent Breisky was significantly influenced by Wilde in his opinions and activities. The thesis sets up three areas to explore that mingle and influence each other: criticism, masque and mystification. The main similarities between Wilde and Breisky are analyzed in the thesis. Based on the comparison of individual motives, it is possible to trace how Breisky builds on Wilde's ideas and what, on the other hand, he invents newly or differently. Apart from the comparison of both authors, the thesis also provides a comprehensive overview of Breisky's opinions on literature and art at the theoretical level. Key words: Arthur Breisky, Oscar Wilde, decadence, critique, art, masque, mystification, dandysm
