Book excerpt: This book uses intermedial theories to study collage and montage, tracing the transformation of visual collage into photomontage in the early avant-garde period. Magda Dragu distinguishes between the concepts of collage and montage, as defined across several media (fine arts, literature, music, film, photography), based on the type of artistic meaning they generate, rather than the mechanical procedures involved. The book applies theories of intermediality to collage and montage, which is crucial for understanding collage as a form of cultural production. Throughout, the author considers the political implications, as collages and montages were often used for propagandistic purposes. This book combines research methods used in several areas of inquiry: art history, literary criticism, analytical philosophy, musicology, and aesthetics.
