One-hundred years ago, Einstein solved the elemental mystery of the nature of light: it is both an electromagnetic wave and a stream of particles. It is a form of energy that moves at a speed of 299.792.458 m/s. It is a medium like no other, and nothing has revolutionized and democratized our world in the way that the control of electric light has.~We live in cities and gardens of light. For almost a century, artists have been working with light bulbs, fluorescent and neon, spotlights or LEDs, to cultivate these gardens. Light Art. Artificial Light offers a broad overview of the development of this genre, from the pioneers of light art in the 1920s to the immersive, interactive environments of ZERO, GRAV, Gruppo T and Gruppo N. Outstanding contemporary pieces, fascinating, profound illuminated spheres, ironic cross-references and plays of filigreed light complete this glowing spectrum of work. Featured artists include Vito Acconci, Olafur Eliasson, Tracey Emin, Dan Flavin, Zaha Hadid, Jenny Holzer, Mike Kelley, Julio Le Parc, Mario Merz, László Moholy-Nagy, Bruce Nauman, Jorge Pardo, Tobias Rehberger, Anselm Reyle, Jason Rhoades, Keith Sonnier, Yves Tinguely, James Turrell and Chen Zhen.
