Matthew Barney is an American artist who works in sculpture, photography, drawing and film. His early works were sculptural installations combined with performance and video. Barney uses video to perfect his sculpture by evaluating positioning, lighting as well as size and shape, using video as a means to his end product of sculpture. Most recently, Barney has explored live performance before an audience. The pieces Ren and Guardian of the Veil revisit the language of the Cremaster Cycle, via a ritualistic exploration of Egyptian symbolism inspired by Norman Mailer's novel Ancient Evenings.
