This book is dedicated to Staccioli’s project methodology, his own way to produce ideas and to develop them to become actual installations and works of art. From the very first photographic “reconnaissances” in situ to the first drawings, to the photomontages, to the executive projects and the actual building phase. An overview of a selection of Staccioli’s installation arts is presented by accurate and detailed reports (compiled by Maria Laura Gelmini by using texts by Staccioli himself) and a rich iconographic apparatus including drawings, sketches and photos by Staccioli. The book includes a preface by Gillo Dorfles and texts by Luca Massimo Barbero and Marco Bazzini. This book is published with the collaboration of the Galleria il Ponte in Florence and the Galleria d’Arte Niccoli in Parma on the occasion of the exhibition dedicated to Mauro Staccioli at the Centro per l’Arte Contemporanea Luigi Pecci in Prato (November 1st 2008 - January 11th 2009). Mauro Staccioli (Volterra, Tuscany 1937) dedicated himself to sculpture from the late 60s, by choosing to work in close connection with the spaces of the urban landscape. He exhibited and realized installation arts in both indoor and outdoor environments in many contexts and cities such as San Diego, Munich, Seoul, Bruxelles, Taiwan, Andorra, Puerto Rico, Barcelona, Venice, Milan, Rome, Florence. He lives and works between Milan and Volterra.
