This essay focuses on the fifteenth episode of James Joyce’s Ulysses (1922), “Circe”, which is written in the form of a drama script. My claim is that in “Circe” Joyce subverts the traditional Western view of drama, established by Aristotle in Poetics (c. 335 BCE), particularly with respect to the principles of imitation, the plot structure, the process of interpretation, and the role of dramatis personae. The focal point of the analysis, also inspired by the ancient critical text, will be Joyce’s vision of the categories of time and space and their implementation in “Circe”.
