His importance refers back to his realistic portrayal of the Irish society in general and of Dublin in particular. It is his experience in the slums of Dublin that provides him with the details that he employed in his plays. The study aims at proving that by describing Dublin slums, O’Casey indirectly directs a criti cism of the social and political reality as a background of the bloody events that Ireland witnessed. The plays that are going to be studied are The shadow of a gunman, Juno and the Paycock, Red Roses for me. Unlike other Irish dramatists who idealized Ireland, O’Casey reveals the contradictions in the Irish society. Thus, the study concludes that O’Casey is distinguished from other Irish writers in avoiding the idealized portrayal of Ireland and offers us a mock-heroic treatment of his society Keywords: O’Casey; Mock-heroism; Dublin city; Dublin's Trilogy .post -colonial literature, Irish drama. 1 Introduction Probably more than any Irish dramatist, the figure of Sean O'Casey is still considered to be the greatest among those who benefited the Irish Dramatic Movement.

However; it was when O'Casey was eight years old when his father died, leaving the family facing Poverty in Dublin slums.

However, he taught himself to read and write at home Because of an eye-disease that prevented him from studying at School. (Stanley1984, 6) Though he is a descendent from a religious family, he gives up Christianity and adopts Communism as his ideology. In his twenties, O'Casey becomes politically active and joins the Irish labour party in a search of new values. Since his active rule in the Irish politics, he becomes the secretary of the Irish Citizen Army. This army was made for self-defense O'Casey also took Part in the Easter Rebellion of 1916. But he withdrew because of his disappointment in the absence of positive constructive action in the Citizen Army.(ibid )His first literary achievement was the publishing of stories about his political experience. This book was entitled as The Story of the Irish Citizen Army. Realizing
