A Skeleton Key to Finnegans Wake is a 1944 work of literary criticism by mythologist Joseph Campbell and Henry Morton Robinson. The first major text to provide an in-depth analysis of Finnegans Wake (James Joyce's final novel), A Skeleton Key to Finnegans Wake is considered by many scholars to be a seminal work on the text. Campbell and Robinson began their analysis of Joyce's work because they had recognized in The Skin of Our Teeth (1942), the popular play by Thornton Wilder, an appropriation from Joyce's novel not only of themes but of plot and language as well.
