Towards the end of the 19th century Oscar Wilde wrote the four society plays that would become his most famous dramatical works: Lady Windermere’s Fan (1892), A Woman of No Importance (1893), An Ideal Husband (1895) and The Importance of Being Earnest (1895). The plays combined characteristic Wildean witticisms with cunning social criticism of Victorian society, using stereotypical characters such as the dandy, the fallen woman and the “ideal” woman to mock the double moral and strict social expectations of Victorian society. These plays, and to an extent also Wilde’s symbolist drama Salomé (1891), have been the object of a great deal of scholarly interest, with countless studies conducted on them from various angles and theoretical perspectives. Widely under-discussed, however, are Wilde’s two Elizabethan-Jacobean tragedies, The Duchess of Padua (1883) and A Florentine Tragedy (1894). This thesis therefore sets out to explore The Duchess of Padua and A Florentine Tragedy in order to gain a broader understanding of Wilde’s forgotten dramatical works, while also rediscovering two of Wilde’s most transgressive female characters—Beatrice and Bianca. Challenging traditional ideas of gender and female sexuality, Beatrice and Bianca can be read as proto-feminist figures who continually act transgressively, using their voice and agency to stand up against patriarchy and asserting their rights to experience their lives on their own terms. Through an in-depth study of these plays, this thesis will demonstrate that Wilde’s Elizabethan-Jacobean tragedies, with their strong, modern female characters Beatrice and Bianca deserve greater critical attention on a par with the extensive scholarship on Wilde’s well-known dramatical works.
