The play Manfred is one of Byron's most famous and influential works. It established him throughout Europe as a bold, blasphemous genius. It inspired music by Tchaikovsky and Schumann, and was admired by, and influenced, Richard Wagner, whose uncle made one of its eighteen German translations. Going back to the primary manuscripts, Peter Cochran has created a new text of Manfred, so that it can at last be read as it left Byron's pen, untouched by professional polishers, too anxious to impose a formal syntax on his fluent and spontaneous style. Cochran has - through a careful study of the original texts - decoded one hitherto-illegible note which throws light on Byron's strange and elaborate demonology. Several essays cover the myriad sources of the play, and there are sections on its production history. Cochran ends with an amusing essay on how to, and how not to, bring Byron's Manfred to the stage.
