This is the first full-length study of Shelley's plays in performance. It offers a rich, meticulously researched history of Shelley's role as a playwright and dramatist and a reassessment of his "closet dramas" as performable pieces of theatre. With chapters on each of Shelley's dramatic works, the book provides a thorough discussion of the poet's stagecraft, and analyses performances of his plays from the Georgian period to today. In addition, Mulhallen offers details of the productions Shelley saw in England and Italy, many not identified before, as well as a vivid account of the actors and personalities that constituted the theatrical scene of his time. Her research reveals Shelley as an extraordinarily talented playwright, whose fascination with contemporary theatrical theory and practice seriously challenges the notion that he was a reluctant dramatist. This study is a major contribution to recent reassessments of Shelley's work and an invaluable resource for anybody interested in Romantic writing and the history of theatre.
