Arnaldo Pomodoro thinks of his massive, architectural sculptures as “crystals, or nuclei, or as eyes, or signal fires,” he says. ”I see them as relating to borders and voyages, to the worlds of complexity and imagination.” Drawing on his training in architecture, Pomodoro’s concerns center on the relationship between each individual sculpture and the space in which it is installed. Early on, admiration for Paul Klee prompted the artist to translate Klee’s linear drawings into dimensional elements in his early relief sculpture. Ultimately, however, Pomodoro became known for large, free-standing geometric forms, especially columns, cubes, pyramids, spheres, and discs. Works such as Rotator with a Central Perforation (1969)—a bronze sphere—exemplify his smooth, streamlined style and devotion to idealized shapes, often reminiscent of Constantin Brancusi. Unlike many of his contemporaries, Pomodoro insists on partaking in the physical fabrication of his work.
