Rogelio Polesello’s, Untitled (1972) exemplifies his mature engagement with optical perception and the dissolution of boundaries between object, space, and viewer. Executed in polished, transparent acrylic, the work operates less as a static form than as a perceptual instrument—one that actively manipulates vision. Its smooth, lens-like surfaces refract and distort whatever lies behind and around it, fragmenting reality into shifting fields of light, compression, and expansion. In this way, the sculpture does not present an image so much as it generates one through the act of viewing.

Rooted in Polesello’s Op Art background, the piece extends his earlier explorations of illusion from the painted surface into three-dimensional space. The clarity of the acrylic belies the visual complexity it produces: straight lines bend, planes dissolve, and forms appear to pulse as the viewer moves. The sculpture’s optical effects are never fixed; perception is contingent upon angle, distance, and ambient light, emphasizing Polesello’s belief that vision itself is unstable and subjective.

The Untitled work also reflects Polesello’s interest in viewer participation. The spectator becomes an active collaborator, completing the work through movement and observation. By incorporating the surrounding environment into its visual field, the sculpture collapses distinctions between artwork and world, echoing the kinetic ambitions of the 1960s and early 1970s while maintaining a distinctly refined, minimalist elegance.

Ultimately, this sculpture stands as a quintessential example of Polesello’s contribution to twentieth-century abstraction—an object that transforms perception into experience and vision into a dynamic, ever-changing event.

Rogelio Polesello (1939–2014) was a pioneering Argentine artist whose work played a central role in the development of Op Art and kinetic abstraction in Latin America. Born in Buenos Aires, Polesello showed an early aptitude for drawing and visual experimentation, and he began exhibiting his work while still a teenager. Largely self-taught, he quickly distinguished himself through a sophisticated command of geometry, optics, and perceptual illusion—concerns that would remain at the core of his artistic practice throughout his career.

In the late 1950s and early 1960s, Polesello became associated with the international Op Art movement, exploring how repeated patterns, contrasts, and distortions could activate the viewer’s eye. His paintings and reliefs often employ grids, concentric forms, and rhythmic line structures that appear to vibrate, expand, or shift depending on the viewer’s position. Rather than depicting motion, Polesello’s work creates the experience of movement through optical effects, engaging perception itself as a subject.

One of his most significant innovations was the use of acrylic lenses and sculptural optical objects, which refract and fragment images of the surrounding environment. These works blur the boundaries between painting, sculpture, and architecture, inviting active viewer participation. The spectator becomes an essential component of the artwork, as perception changes with movement, light, and angle.

Polesello achieved international recognition early in his career, representing Argentina at major exhibitions such as the Venice Biennale and showing widely in Europe, the United States, and Latin America. His work was exhibited alongside leading figures of kinetic and Op Art, including Victor Vasarely and Jesús Rafael Soto, while retaining a distinct identity rooted in Argentine modernism.

Today, Rogelio Polesello is regarded as a key figure in twentieth-century abstraction. His work remains influential for its rigorous visual intelligence, technical innovation, and enduring ability to challenge how viewers see and experience space, form, and perception itself.
