One of the most stirring art forms to emerge in the '90s is Joshua Neustein's installations of ash cities. These are three-dimensional maps created out of industrial slag, byproducts of the coal and electric industries, installed on huge museum floors where viewers are invited to wander about within the exhibit. This book illustrates five installations in 90 splendid color and black and white photographs. It contains as well four groundbreaking essays by Arthur Danto, Hilary Putnam and Kristine Stiles. The text is in English and Hebrew with excerpts in Arabic.
