Deeply informed and appealingly written, this revised and updated second edition gives fresh life to the enthralling sexual, poetic and political contradictions that make Byron the first literary celebrity. Encompassing his entire oeuvre, the volume both provides an authoritative guide for students, and points to emerging new areas of research, highlighting Byron's ongoing relevance in an increasingly complex world both within academia and beyond. Published to coincide with the 200th anniversary of his death, new chapters cover investigations of Byron's manuscripts, his relationships with nonhuman animals, his levity and addiction, and his Dramas and their reception.
