In 1913, Epstein created an astonishing figure now recognised as the sculptural masterpiece of the Vorticist movement. It comprised a life-size plaster figure of a visored robotic man seated upon an actual rock drill. It was shown briefly in 1915 before being dismantled. This is a reconstruction made in 1974 from Epstein's studio photographs. The disturbing figure was conceived as Europe slid into the chaos of the First World War. It reduces the human form to a faceless robot, at one with the machine it straccles - an appropriate symbol of the first mechanised conflict.
