A committed student of vernacular literatures alongside classical ones, Shelley matured a deeply integrated vision of European literature as a transnational conversation including the English-language tradition. This conception informs his literary and theoretical writings, his reflections about and practice of translation, and his appropriations and recreations of foreign forms and modes, such as Dante’s terza rima or Petrarch’s Trionfi. His interests focused especially on the Renaissance (in France, Italy, and Spain) and the eighteenth century and Revolutionary period (especially in France) and on figures such as Michel de Montaigne, Pedro Calderón de la Barca, Johann Wolfgang von Goethe, or Madame de Staël and the members of her salon at Coppet. Shelley’s engagements with modern European literatures confirm him as a poet and thinker poised between classical and post-classical cultures, harnessing them to support his revolutionary approaches to versification and poiesis, political and philosophical reflection, and cultural-social activism, against the backdrop of an incessantly evolving modernity.
