The Italian artist Medardo Rosso (1858–1928) was instrumental in expanding the definition of sculpture for the modern era. Not only did he focus on everyday, contemporary subjects, but he also experimented with light in order to render sculpture ephemeral and seemingly insubstantial. His heads and figures—frequently portrayed as tired, meditative, laughing, or melancholy—appear to be caught in fugitive visual, physical, or emotional states. As fleeting “impressions” of modern life, they stand in marked contrast to the monumental, idealized depictions typical of traditional sculpture before and during the nineteenth and early twentieth centuries. Medardo Rosso: Experiments in Light and Form is the first comprehensive US museum exhibition of the artist’s work in over fifty years, featuring nearly 100 works that include sculptures, drawings, and photographs.
