1960s Op Art translucent acrylic cube sculpture by Argentine author Martha Boto By: Martha Boto Material: acrylic, plastic, synthetic, metal Technique: cast, molded, polished, metalwork, machine-made Dimensions: 23.75 in x 23.75 in x 23.75 in Date: mid-20th century, circa 1960 Style: Mid-Century Modern, Op Art Place of origin: Argentina A rigorous exploration of geometry and perception, this translucent acrylic cube by Argentine artist Martha Boto articulates the visual language of Op Art through clarity, structure, and reflective interplay. Constructed from precisely cast and polished acrylic panels arranged in a gridded framework, the cube encloses a constellation of suspended metallic spheres whose mirrored surfaces multiply and refract their surroundings. The internal vertical supports and measured spacing of each element generate shifting optical relationships, activating the volume as light penetrates and ricochets across planes and curves. Born in Buenos Aires in 1925 and later active in Paris, Boto was a co-founder of the Grupo de Artistas No Figurativos de la Argentina and a key figure in the development of kinetic and programmed art. Her practice consistently investigated movement, seriality, and the dematerialization of form through industrial materials. Here, the dialogue between transparent structure and polished metal encapsulates her commitment to systematic composition and perceptual dynamism, resulting in a work that is both architectonic and visually fluid.
