This is a fully modernized, annotated edition of John Ford's controversial tragedy of sibling incest and complex revenge plots. As with all Arden editions, it features detailed on-page commentary notes to help the reader understand and appreciate the play both in performance and as a many layered literary text. The comprehensive introduction offers a wealth of critical and contextual information and explores the controversial theme of incest from an early modern perspective. Editor Sonia Massai reveals the startling originality of the play, which is far more than a dark rewriting of Romeo and Juliet, and explores the reasons for the play's enduring appeal to modern audiences.
