However varied the media in which the American artist Roni Horn expresses herself, it is a single theme that preoccupies her in her photos, sculptures, installations, drawings and texts: the changeable, inconsistent nature of identity. By mirroring pairs of images or objects, for example, the artist – who was honored in 2009 with a major retrospective at the Tate Modern, London and the Whitney Museum of American Art in New York – creates an interplay between similarity and difference that has a disconcerting effect on the viewer. The latter can enter into the framework of an alleged me-and-you relationship, or seek himself in the gaze of a photographed face directed towards or away from him. Particularly Roni Horn’s photographic portraits, which are arranged in sequences, invite participation in such dialogue. In 2013, in an exhibition project designed especially for the SCHIRN, the artist will present one of these series in the exhibition hall’s rotunda as well as – in the form of an intervention – in the urban space of Frankfurt. Portraits will encounter us silently and without context at various locations; the question as to whether we find ourselves in them or are unsettled by the subjects' gazes will remain unresolved.
