Thesis advisor: Joseph Nugent / In this paper, I unite scholarly understanding of T. S. Eliot’s recurring character, Sweeney. I present the origin of Sweeney through Eliot’s knowledge of classical and Irish myth as well as his contemporary views surrounding Ireland, Catholicism, Africa, and Afro-modernism. In discussing dramatic Sweeney, I incorporate an understanding of Eliot’s contemporary works on Senecan tragedy to unravel the fragmented nature of “Sweeney Agonistes.” I conclude my first chapter by discussing Sweeney’s “death” by analyzing Eliot’s recent conversion to Anglicanism and emerging views of poetic metaphysics. My second chapter unveils the ghost of Sweeney in Eliot’s “Murder in the Cathedral” through the metaphor of stencil art, discussing “Sweeney Agonistes” as an outline. Further, I find Sweeney’s ghost in the work of Samuel Beckett’s "Waiting For Godot" through analysis of themes drawn from an article by Rick De Villier, as well as new studies on technique and characters. I conclude with my explanation of Sweeney as a “new” Senecan Tragic Hero based on the terminology of semper idem - always the same. / Thesis (BA) — Boston College, 2024. / Submitted to: Boston College.
