James Joyce`s Ulysses is a novel which deals with such a multitude of subjects in such a diversity of manners that it is substantially impossible to give a definitive articulation of its overall theme. Here arises the need to try to vary the way in which the work can be read. One useful way to do this is to frame the work, overall or partial, in a variety of contexts. It seems possible to propose three frames of reference for contextualizing the book: `facet`, which refers to the horizontal, or directional, axis that makes it possible to view an element from different angles; `scale`, which refers to the vertical, or dimensional, axis that helps an element to be viewed from varied ranges of perspective; and `level` which refers to the common axis combining the two. Again, there can be proposed several kinds for each axis: four facets-narrative, psychological, symbolic, and mythic; four temporal scales-the moment of an event happening, a day, a lifetime, and the history of mankind; and two levels-moral and epistemological. By means of these contextualizing frames, one might, instead of attempting to pinpoint the theme of the book, consider the nature and significance of what has happened on Bloomsday: firstly, focusing on the two most important event of the day-the meeting between Bloom and Stephen and the affair of Molly and Boylan-and, secondly, discussing on the overall plane of the text the significance and consequence of the day`s happening. The present essay tried to illustrate according to varied facets, scales, and levels how the day`s happenings, especially the two major ones, can be differently interpreted in different contexts. It also tried to make use, in investigating the consequence of Bloomsday in particular, of the term "concrete universal" referring to the paradoxical manner in which specificity and universality are not only contained together in a given element but also interrelated in a complementary and interdependent way. To make a rough simplification in terms of concrete universal, much has happened in the smaller context, and little in the larger context. Ulysses in this sense is, on the plane of manner as well as matter, an excellent embodiment of Joyce`s flexible vision of life that accommodates the multilateral and interrelated contexts and levels.
