This book explores the significance of photography for Iain Sinclair’s London prose. The visual medium is one of the writer’s most prominent motifs, featuring extensively in his fiction and non-fiction. This study, however, proposes that its role in Sinclair’s work extends beyond that of a literary theme, to an actual literary principle. In its interdisciplinary rereading of his writing, this book uses key notions of photography theory to examine the correlation between the principal ideological aspects of the visual medium and the main characteristics of Sinclair’s unique brand of literature. The analysis reveals that photography may actually serve as a key to understanding the peculiar dynamics and inherent pluralities that define the writer’s literary practice.
