This is the first variorum edition of the 1890 and 1891 editions of Oscar Wilde's controversial novel, 'The Picture of Dorian Gray'. Drawing on manuscripts and a typescript, this volume reprints the thirteen-chapter and twenty-chapter versions of Wilde's narrative as separate works, enabling the reader to see the considerable changes that Wilde made to his famous story across a period of eighteen months. This variorum edition contains a comprehensive introduction that provides full bibliographical information about the two editions, as well as a detailed commentary that illuminates the extraordinarily wide range of references that Wilde makes to a broad repertoire of sources. This volume will be the definitive edition of 'The Picture of Dorian Gray' for many years to come.
