Sol LeWitt (1928–2007) is counted among the most influential figures in postwar American art. Emerging in the 1960s amid the rise of minimalism and conceptual art, LeWitt replaced the emotional expressionism of earlier generations with a rigorous focus on systems, structures and ideas. His works, from modular ‘structures’ based on cubes to his celebrated Wall Drawings, transformed how art could be made, perceived and even authored. As he famously wrote in his 1967 essay Paragraphs on Conceptual Art, ‘The idea becomes a machine that makes the art.’
‘Open Structure’ is the first major public museum survey of the artist’s work in Japan. Spanning wall drawings, sculptures, works on paper and artist’s books, the exhibition traces LeWitt’s lifelong pursuit of an art of pure thought and open form. Six wall drawings, realised by local teams following LeWitt’s own detailed instructions, invite viewers to experience his radical redefinition of authorship and collaboration.
Highlighting LeWitt’s ‘open structures’, the exhibition reveals how his skeletal cubic forms, stripped of surface and solidity, expose the underlying architecture of thought. The artist’s enduring influence lies in his conviction that ‘ideas cannot be owned; they belong to whoever understands them’.
