Charles Baudelaire is usually read as a paradigmatically modern poet, whose work ushered in a new era of French literature. But the common emphasis on his use of new forms and styles overlooks the complex role of the past in his work. In "Grotesque Figures, " Virginia E. Swain explores how the specter of the eighteenth century made itself felt in Baudelaire's modern poetry in the pervasive textual and figural presence of Jean-Jacques Rousseau. Not only do Rousseau's ideas inform Baudelaire's theory of the grotesque, but Rousseau makes numerous appearances in Baudelaire's poetry as a caricature or type representing the hold of the Enlightenment and the French Revolution over Baudelaire and his contemporaries. As a character in "Le Pome du hashisch" and the "Petits Pomes en prose, " "Rousseau" gives the grotesque a human form.Swain's literary, cultural, and historical analysis deepens our understanding of Baudelaire and of nineteenth-century aesthetics by relating Baudelaire's poetic theory and practice to Enlightenment debates about allegory and the grotesque in the arts. Offering a novel reading of Baudelaire's ambivalent engagement with the eighteenth-century, "Grotesque Figures" examines nineteenth-century ideological debates over French identity, Rousseau's political and artistic legacy, the aesthetic and political significance of the rococo, and the presence of the grotesque in the modern.
