Allen S. Weiss has written a beautiful pioneering piece of work, which unfolds, among other things, a thrilling account of how natural beauty has been determined by our arts since the Renaissance. Each of the chapters is documented by a wealth of philosophical and artistic material, astutely brought into play and shown in its multifold interrelationships....As ever, Weiss uses history in a fresh and imaginative (and even subtly perverse!) manner so that Unnatural Horizons, with its original iconography and the delightful music of its language, sounds very much like a Gesamtkunstwerk in itself. It is, indeed, a masterwork.
