Roni Horn is a contemporary artist who chips away at our certainties and presents a world which seems familiar yet turns out to be quite elusive. It’s an experience to be commended to anyone who presumes to lead people or to understand the environment with which they are engaged.
An exhibition of her work is at Tate Modern. It consists largely of sculpture and photography. There is a great deal of repetition and variation on a theme and it’s easy to view the work quickly and think you have grasped it. But it gets under your skin and eventually challenges your preconceptions, encouraging you to question perception itself.
