Diploma thesis called Josef Čapek (monographic study)focuses on Josef Čapek's literary discourse. On the one hand it deals with the meanings of topics and motives, which were crucial for Čapek's writing in the relation with the whole author's work, on the other one it concentrates on formal characteristics of Čapek's literary language. Thesis also attempts to answer the question whether Josef Čapek followed contemporary literary tendencies or whether his works differed and if they did, then how. The relationship between Čapek's writing and paintings is also important, therefore the thesis examines whether his painting activity somehow reflected in or even directly influenced his literary works. The whole thesis is divided into eight chapters, by which we suggest to structure also whole Josef Čapek's literary work itself into eight periods and areas. Bibliography, mapping published first editions of his texts, reception and reflection of his literary works, paintings and his own personality, is also important part of the thesis.
