‘Ecstasy’: the term spans the timeline of Shakespeare’s work, registering for the first time in The Comedy of Errors and last in The Tempest. Commonly glossed as ‘madness’ or ‘frenzy’ by modern editors, this chapter seeks to broaden and productively complicate our understanding of this word and the state it denotes. Tracing it through Shakespeare’s work and contextualizing it within classical and early modern thought, this chapter returns ecstasy to its etymological sense of being out of place—from the Greek ἐκ (out) ἱστάναι (to place or stand). Taking The Comedy of Errors as its central text, it highlights the errant nature of ecstatic experience and reads the Antipholus twins—and their designations of ‘Erotes’ and ‘Sereptus’ in the First Folio—as models of ecstatic subjectivity that reflect the play’s broader concerns with issues of emotion, identity, and place.
