Did You Know?
A curator of education bought this object in 1954 with the intention of making it a gift of the artist, but apparently the museum was perplexed over its status as a work of art, and did not formally add it into the collection until 2000.Description
Thomas Wilfred was a pioneer in using light as a primary artistic medium, and he coined the term lumia to describe his new art form. This early example is a cabinet with an interior mechanism incorporating a lightbulb, motor, hand-painted glass disc, and reflective surfaces, all of which operate in unison to project abstract images in motion and color against a screen. The viewer can turn exterior knobs to manipulate these projected compositions. The artist named this device a Clavilux, after a Latin word meaning “light played by key.”- 1930–2000Collection of the artist, given to the Cleveland Museum of Art2000–The Cleveland Museum of Art, Cleveland, OH
