Too many landscapes have been reduced to silent commodities by being put into golden frames on top of our fireplaces. Too many landscapes have been reified by being considered as objects holding forth referents to an omnipotent looker-on, with his/her language ever ready to seize and transcribe. The articles gathered here, prolonging an international conference held at the University of Caen Basse-Normandie (France), 14-16 June 2007, set the landscapes loose again by engaging with their essentially relational quality.What makes this volume particularly stimulating and critically innovative is this initial acknowledgement of a landscape's reflectiveness - that is the fact that it contains unthought thought, and thus presents itself to us both passively and actively. This straightaway appraisal of the lines of flight in the seemingly static, tranquil images facing us, has opened the way to deeply critical readings bent on questioning old tracks, testing new itineraries, denying the closure of the subject. At the same time, and by way of consequence, it leads us to encounter the force in landscape. A force like an energy, an impetus, which makes it possible - if not advisable! - to still compose, read and enjoy landscapes in the XXIst century.
