Stephen Daedalus is one of the three Dubliners, described in the novel (Stephen Dedal, Leopold Bloom and his wife, Marion Bloom). The fundamental shape-forming feature of the novel is the connection with Homer's “Odyssey,” which is expressed in numerous and transparent plot, thematic and semantic parallels, hints, allusions. For most characters of “Ulysses,” the poem of Homer have prototypes: Stephen Daedal is Telehome.
The lines of the three main characters of the novel develop in parallel but are closely intertwined. All three characters - both in the direct and in the figurative sense - travel through the gigantic space of the seven-page novel. Stephen Dedal, with whom the reader is familiar because of Joyce's previous work, is disappointed with life, and with himself, that’s why he leaves early in the morning from the Martello tower and runs into Odyssey over Dublin. It's strange in the capital of Ireland on June 16, 1904 (in the Joyce novel, this day from the life of three people - a symbol not only of the history of Ireland, but also of all mankind), the advertising agent Leopold Bloom, who, like Daedalus, has a good reason to be dissatisfied with his life.
Stephen Daedalus is a Christian martyr Stefan as well. His thoughts are constantly associated with two themes: homeland and religion. On the one hand, he is a patriot of Ireland, on the other, he doesn’t wish to sacrifice his freedom and vocation of the artist. The fact that Dedalus breaks with the church, that he is tormented with a conscience (he refused to fulfill the will of the dying mother and to pray for it), makes him especially happy with Joyce. As a result of a conflict with his friend and envoy Bull Mulligan, he leaves the Martello tower and goes to school in the Dublin Suburbs of the Valley, where he gives a lesson of history.
