Sphere Within Sphere

Sphere Within Sphere describes a series of spherical bronze sculptures by Italian sculptor Arnaldo Pomodoro. In 1966, Pomodoro was commissioned to create a 3.5-meter sphere for Expo 67 in Montreal. The success of this sculpture propelled Pomodoro's works into the mainstream, allowing for commissions that would land his sculptures at the Headquarters of the United Nations and the Vatican Museums.

Over his career, Pomodoro has created 45 of these popular sculptures— aptly named Rotante, Sphera, or Sphera con sphera. The spheres range in size from as small as half a meter up to 4 meters in diameter. They are meant to represent the 'ideal city,' with contrasting imagery of organic and human shapes combined with technological and gear-like components.
