Richard Serra is considered by many to be the most important sculptor of the postwar period. The essays in this volume cover the complete span of Serra's work to date -- from his first experiments with materials and processes through his early films and site works to his current series of "torqued ellipses." There is a special emphasis on those moments when Serra extended aesthetic convention and/or challenged political authority, as in the famous struggle with the General Services Administration over the site-specific piece Tilted Arc.

Each book will trace not only the development of an important oeuvre but also the construction of the critical discourse inspired by it. The series editors are Hal Foster, Benjamin H. D.
