The encounter theme is one of the main subjects in Finnegans Wake and it is pursued constantly through the text. In Finnegans Wake there appear several of important racial encounters between the native Irish and the foreign invaders from the Europe from the primitive age to the modern age. And the fable of `the Mookse and the Gripes` illustrates such an encounter as the encounter between the Irish and the English in the year of 1171 when English King Henry Ⅱ invaded Ireland. Ireland was ceded by the Pope(Pope Adrian) to Henry Ⅱ of England in the 1150s. The age of imperialism began after that time and it has continued over 700 years. Because of the colonial state of his country the theme of national, ethnic, or racial identity is almost constantly before us in all of Joyce`s works. In the fable of`the Mookse and the Gripes` Mooks represents the English King Henry Ⅱ as well as Nicholas Breakspear(Pope Adrian Ⅳ) while the Gripes combines the Irish and Lawrence O`Toole, the bishop of Dublin at the time of Henry`s invasion, 1171 A.D. The confrontation between the invader and the native provoked multi-levelled arguments such as theological, political, and even brother battle resulting from their different positions. And these polarized rival forces became more complex with the entry of their sister, Nuvoletta(Issy) at the end of their arguments. She tries in vain to use her charms to reconcile the Mookse and the Gripes in her own female discourse. When darkness comes, the twin are transformed into Pope`s handkerchief and a butcher`s apron and they are carried off by two washing women. Nuvoletta, a little cloud-girl became raindrops and fall into a river. Nationality, religion, and language are the "nets" from which Stephen in A Portrait declares he will escape. Joyce`s attitude of the repudiating British and Roman imperialisms and rejecting Irish nationalism are reflected in the fable of "the Mookse and the Gripes". Joyce realizes this especially through the radically experimental writing of Finnegans Wake whose language contributes to an ultimate degree of openness in our understanding of history by resisting the authorized canons and totalizing structures.
