This chapter looks at the ‘slippery figure’ of Boethius, whose religious and literary affiliations resist easy categorization, as a touchstone of discipline formation. It shows the ways in which Boethius repeatedly transgresses the generic boundaries imposed upon him by twentieth-century grand narratives of Latinity, focusing particularly on the narratives of E. R. Curtius, C. S. Lewis, and Northrop Frye. Boethius refuses to be corralled or co-opted in the service of either philology or theology: the effort required to construct and maintain a tradition can never fully conceal its own excesses or gaps. Finally, it looks at the way in which the myth of the western classic is dependent above all not on the text but on the codex, the material spine-hinged book.
