The relationship between different media has emerged as one of the most important areas of research in contemporary cultural and literary studies. But how should we conceive of the relationship between texts and images today? Should we speak of collaboration, interaction or competition? What is the role of literary, historical and scientific texts in a culture dominated by the visual? What is the status of images as cultural artefacts? Are images forms of representation, do they simulate reality or do they intervene in the material world? And how do literature and cultural theory - themselves essentially textual discourses - react to the much-discussed visual turn within Western culture? Does the concept of 'intermediality' allow literary, historical and cultural scholars to envisage a more general theory of media? Addressing these questions from a programmatic point of view, the articles in this volume investigate the effects of different forms of representation in modern European and American literature, media and thought.
