This essay reads James Joyce`s Ulysses as a narrative of myth-and-city space. Through this reading, colonial metropolis Dublin, the central subject of this novel, is interpreted as a space where two different time-related spaces-one of which as a historical mythic space and the other as contemporary modern city space-are colliding against each other and producing the moment of `dialectical perspective.` This `dialectical perspective` can be used to offer a revolutionary insight to contemporary people, including those who have been and are being oppressed by state, nation, empire, religion, class, gender or any kind of authoritative power and oppressive history, to change the present politics and society. This revolutionary insight, or awakening from the deceitful social structure or mythic reality could be the first political action practiced by any people who hope the advent of a new utopian community `here and now.` In Ulysses, created by exiled and adult Joyce, who constructs `immediate past` of Dublin through retrospective position, modern metropolis and metropolitan lifestyle are superimposed on mythical environment, which seems to produce various momentums of `dialectical images.` Not only do some characters of the novel show this process of immersing in melancholic, oppressive personal/collective unconsciousness ultimately to awaken from it, but narrative technique and structural style themselves, which are intersected and overlapped throughout the entire work, also contribute to creating this perspective. Dublin as a mythic world and modern city space seems to provide us with a potentiality of moments of this awakening. And this is the strength of narrative strategy of Ulysses, which creates this great actual and literary text.
