"Soto, half magician, half geometer, has succeeded, using plexiglass elements, in making the traditional canvas vibrate, and walks enchanted toward the conquest of countless and unknown dimensions."

—Carlos Raúl Villanueva, "Soto. Kinetic Structures," exhibition brochure, Caracas, Museo de Bellas Artes, 1957

The fourth dimension, as conceived by artists such as Soto, Cruz-Diez, Kapoor, Orozco, Vasarely, and Poliakoff, transcends the conventional boundaries of space and time, guiding us toward an invisible, ever-changing reality.

In the kinetic worlds of Soto and Cruz-Diez, color and movement become agents of transformation, dissolving static perceptions and creating a dialogue between matter and the multidimensional nature of their works. Kapoor explores the void, sculpting spaces where light, darkness, and materiality intertwine to create unfathomable depth, inviting the viewer to confront the infinite. Though Orozco is best known for his historically charged murals, the Mexican artist also studied the different dimensions of painting, with his abstract works offering a channel to glimpse what lies beyond reality. Through Vasarely’s optical labyrinths and Poliakoff’s abstract harmonies, we perceive a hidden architecture of forms, where perception folds in on itself, hinting at dimensions beyond the visible world. These artists, through their respective mediums, offer us a passage into the unknown, revealing the profound elasticity of space and time.
