Russian linesman, frontiers, borders and tresholds

Turner Prize winner Mark Wallinger is one of Britain's most intellectually curious, socially committed and unpredictable artists. He is known for work that formally and conceptually negotiates seemingly opposed elements, like "Sleeper" (2004), in which he spent nine nights in Berlin's Neue Nationalgalerie in a bear costume. For his contribution to the Hayward Gallery's series of artist-curated projects, Wallinger explores the notion of liminality--an intermediate or transitional condition--which is illustrated through the thresholds and borders, simulacra and mirror images found in the work of William Blake, Vija Celmins, Tacita Dean, Thomas Demand, Albrecht Dürer, Bruce Nauman, Guiseppe Penone and Fred Sandback.
