The Furan remains almost invisible within the city of Saint-Étienne. The photographer Pierre Suchet walked its banks from its source, at Le Bessat, to its confluence with the Loire, at Andrézieux-Bouthéon. The meticulous shooting work is combined with the reflections of geographers, historians and image specialists, in order to examine the relations that have been established over time between people and the river. The contemporary photographs also meet, in this book, a whole variety of older representations. This dialogical approach was consciously chosen to try to restore the complexity of the uses made of the river by the inhabitants of the watershed and of their feelings towards the watercourse; it is also determined by the desire to push the reader to invest themselves in a form of investigation.
