“Le Onde: Waves of Italian Influence (1914–1971)” runs Aug. 22–Jan. 3, 2016, at the Smithsonian’s Hirshhorn Museum and Sculpture Garden. This exhibition of nearly 20 works from the museum’s collection follows Italian contributions to the transnational evolution of abstraction, through movements and tendencies such as futurism, spatialism, op art and kinetic art.

The exhibition includes several works that have been exhibited only rarely or not at all since entering the collection. Among those that have not been on view since the Hirshhorn’s inaugural exhibition in 1974–1975 are works by Zero group founder Heinz Mack, French op artist Yvaral and Italian painter Carlo Battaglia and several works by Italian artist Enrico Castellani.
