Lucio Fontana was a post-war Italian avant-garde artist who became famous with his monochrome slash pictures. Fontana also wrote numerous manifestos, in which he demanded the rejection of traditions, the synthesis of genres as well as new materials and concepts of space. Throughout his life, Fontana put these convictions into practice with a large variety of materials. In all of his works, he dealt with the destruction of the support medium or surface to achieve three-dimensionality and reverse the previously two-dimensional substrate. Fontana called these works 'Concetto Spaziale' (Spatial Concept), 'Buchi' (Holes) and 'Tagli' (Slashes). With his works, Fontana influenced the artist groups ZERO, the Nouveaux Réalistes and the Arte Povera.
