American artist Roni Horn (b.1955) is revered around the globe for the understated force of her beautifully composed works of art. She has concentrated on a small, highly personal selection of subjects. For instance, the tradition of Minimalist sculpture and our response to it is transferred with great sensitivity into her artwork. Asphere III, for example, looks like a solid copper sphere: in fact it is slightly distorted and thus asymmetrical. Horn frustrates our notions of contemporary sculpture, sharpening our awareness of experiencing the work and offering a heightened sense of environment and presence in the world.
