This thesis explores topics of gender, sexuality, and male and female agency in Restoration literature and theatre, specifically Aphra Behn’s The Rover (1677) and The City Heiress (1682), William Wycherley’s The Country Wife (1675), and Sébastien Brémond’s Hattige; or the Amours of the Prince of Tamaran (1680). It explores how these authors understand and explore the ways in which both genders were confined by dominant models during this time period, while also navigating the fluidity and complexity of these models. This thesis focuses on how libertinism and its emphasis on sexuality relates to gender categories. Given that access to libertinism is dictated through social class, sexuality, and wit, certain aspects of libertinism can be available for women. While women cannot completely do this and dominate men in the same way, they can harness parts of this libertine role, although they still must be careful about their reputation and honour. This thesis explores topics of the libertine figure and other categories of gender in relation to that figure through its representation in popular genres of Restoration literature (comedy and amatory secret history), arguing that as represented in these texts, sexuality and gender are constitutive of one another.
