In this excerpt from "Lumia: Thomas Wilfred and the Art of Light," celebrated artist James Turrell offers a recounting of his first experience seeing the art of Thomas Wilfred (1889–1968), whose unprecedented works prefigured the field of light art in America. Turrell’s foreword is followed by curator Keely Orgeman’s in-depth discussion of Wilfred’s spellbinding art form, which he called "lumia"—silent, kinetic works in which the artist used electrical, reflective, and mechanical elements to direct light onto translucent screens, producing multicolored compositions that often mimic the effect of the aurora borealis rhythmically pulsing in the night sky.
