This chapter examines some of the most important poetic influences on Shelley’s writing from the tradition of poetry in English published before his birth in 1792. In particular, it focuses on Shelley’s inheritance of works by Spenser, Milton, and Shakespeare while acknowledging the breadth of his reading and its influence on his own poetic practice (the chapter also acknowledges that Shelley’s inheritance from English poetry must be considered in the context of his inheritance of work in Greek, Latin, and a range of modern European languages, which is discussed elsewhere in this volume). The chapter attempts to tease out some of the ambivalences in Shelley’s relation to his poetic forebears, taking Spenser – royalist and imperial apologist, which Shelley emphatically was not – as a crucial example here.
