French artist Daniel Buren is the creator of hundreds of installations that have marked the landscape of contemporary art. He has now conceived a unique work to occupy, for an entire month’s time, the central empty space of the Guggenheim Museum. But no matter how spectacular it may be, this work – whose creation and installation will mobilize the artist and the Museum (curators, engineers, technicians, security) for several months – is simply the conclusion of a story that began thirty-five years earlier.
