Under the perspective of media culture theory，Finnegans Wake could be considered as a metaphor for the media transformation. On the one hand，the novel emerges the metaphor relationship between media technology transformation and human historical evolution from tribulation to de-tribulation，re-tribulation，and return. On the other hand，it reveals the anti-environment function of literature，points out the significance of creating imagination，remediation function of media，and aesthetic self-disciplinary limit of literary innovation. Meanwhile，the novel reveals the inter-transformation between architype and cliché，develops the way of literary innovation. The media metaphor implicates the change of human perception and comprehension about art，which provides us a typical text to rethink literary termination theory.
