Malcolm Lowry's Under the Volcano is now recognized as one of the major novels of the 20th Century, whose breadth and experimental prose have influenced a wide range of contemporary writers. This study, originally published in 1984, considers the significance of the autobiographical elements in Lowry's writing, in the context of his developing concern with fictionality and the romantic sensibility. It gives special attention to his exotic many-sided masterpiece and discusses the ways in which the narrative's reflexive games-playing elements affect the representation of character, history, myth and magic. It surveys Lowry's late experimental novels and stories and considers how their metafictional aspects anticipate some key interests of contemporary writing.
