Landscape exerts a subtle power over people, eliciting a broad range of emotions and meanings that may be difficult to specify. This indeterminacy of affect seems, in fact, to be a crucial feature of whatever force landscape can have. As the background within which figure, form, or narrative act emerges, landscape exerts the passive force of setting, scene, and sight.
