This book revisits Oscar Wilde's major writings through the field of performance studies. Wilde wrote about performance as a cultural dialectic, as a form of serious and critical play, and as the basis of a subversive poetics. In his studies at Oxford University, his famous lecture tour of the United States and Canada, his friendships with famous actresses Sarah Bernhardt and Lillie Langtry, the writing of his critical essays, 'The Picture of Dorian Gray, Salome,' and his society comedies, and culminating in his post-prison writings 'De Profundis' and 'The Ballad of Reading Gaol,' Wilde develops a rich theory of performance that addresses aesthetics, ethics, identity and individualism. This book also traces Wilde's often-troubled relationship with late-Victorian society in terms of its attempts to define his public performances by stereotyping him as both irrelevant and dangerous, from the early newspaper caricatures to its later description of him as a sexual monster.
