The four essays of this book discuss gardens of the Middle Ages and Renaissance whose traces are still visible at sites in Italy and France: Palermo and Rome, the Vaucluse and Hesdin. These gardens have been emptied of the life that gave them shape and in the intervening years they have been transformed in such a way as to entangle and obscure significant moments of their past. Examines these places as installations within a more enduring environment in much the same way that temporary "ambient architecture" -- the architecture of the stage set, the showroom and the festival -- stands within the framework of building and city. Acknowledgments, prologue, notes, bibliography and index. 78 color and black and white illustrations.
