Published on the occasion of the eponymous exhibition at David Zwirner in 2015, "Corners, Barriers and Corridors" takes as its point of departure Dan Flavin's (1933-96) influential "Corners, barriers and corridors in fluorescent light from Dan Flavin" show, presented at the Saint Louis Art Museum in 1973. The volume brings questions of architecture to the fore, exploring how this particular body of light works function in space. Mining early explorations in Flavin's practice, the book includes many works reproduced for the first time in plates that accurately capture their colors. Above all, the photography reveals the unexpected and powerful interplay between the light of Flavin's constructions and the surrounding space; these works not only function as color experiments but as structural explorations in light. This catalogue presents an especially significant body of work, along with new scholarship by Michael Auping, offering a vital historical perspective on Flavin's practice.
