In 1931, Alexander Calder, an influential figure of kinetic art, developed his first “mobile” or kinetic sculpture. As demonstrated in Four at Forty-Five Degrees, Calder’s sculptures articulate space rather than mass, and define volume with open, wiry structures that gently move in air. Triangles and Arches represents Calder’s later work of the 1960s created from large sheets of steel that recall architectural and environmental themes. A focal point of the Empire State Plaza, the triangular forms of Triangles and Arches mirror the Gothic spires of the Cathedral of Immaculate Conception located southeast of the Plaza.
