Lucio Fontana was an Argentine-Italian artist. He is mostly known as the founder of Spatialism. Throughout his prolific career, Lucio Fontana demonstrated a relentless interest in the relationship between surface and dimensionality. Fontana implemented his theory in his series Concetto Spaziale (‘spatial concept’), punching holes in the picture plane and slicing through his canvases in order to expose the dimensional space beneath. Fontana’s innovative theories prefigured later developments in environmental art, performance art, and Arte Povera.
