This book is devoted to the installation at the Chinati Foundation in Marfa, Texas, by the great light and space artist Robert Irwin. After seventeen years of preparation the artwork opened to the public in July 2016. Along with the buildingdeveloped by Irwin, with its directed lighting filling the spacethe design of the courtyard forms an apex in the body of work by this pioneer of contemporary American art. At the same time, it fulfills the long-cherished wish of Donald Judd, the founder of the Chinati Foundation, to have a major work by Irwin in his artists museum. This monograph describes Irwins friendship with Judd and Judds interest in Irwins art, which led to an invitation to Marfa in 1999. It presents Irwins work in photographs documenting the light over the course of a year. Essays, drawings, floor plans, and other pictures show this work within the larger context of Irwins oeuvre and the Chinati Foundations collection.
