This paper proposes that in the episode of "Oxen of the Sun," Joyce`s experiments with prose styles suggest how to write history. First, he uses various imitations and parodies of styles to describe a bull session, which implies we can get to the truth of history by "looking at it from many different angles and in many different lights." Various points of view will help the history writer overcome the ideological or imaginary elaborations he or she otherwise would be subject to. Second, Joyce suggests history is written in terms of progression or succession, not development or growth. Not going by his letter to Budgen, Joyce sometimes reverses chronology of styles and repeats some words or phrases irrespective of their chronological sequence. Additionally, into the final stage of stylistic "development" emerges the chaos of modern "marketplace" speech instead of full growth of post-Carlyle style. Such reversals, repetitions and disintegrations do not support linear development of history. Third, during the bull session young Irish people criticise their historical past related to their home, religion, and politics. To criticise historical past is to see/write the history in the light of the present. As history is "an unending dialogue between the present and the past," the present is the key to the writing of history. To conclude, it is his ideas of history writing that Joyce suggests through "a museum of literary styles."
