Thanks to Paolo Marton's photographs, this is a very beautiful book. There are artfully shot exteriors of all the buildings, including some very romantic shots of villas on the verge of decay, and some stunning shots of frescoed interiors. Judging by the models of car appearing in some of the shots of Vicenza, Marton has delved way back into his own archives for this book; but that is not a criticism. The photographs are supplemented by numerous plans, sections and elevations, though not in all cases. Disappointingly there are few photographs of church interiors and a few double page spreads appear grainy and over enlarged.
The text by Pape and Wundram contains some interesting archival research, but is very much the work of art historians rather than architects. Notably they (or their translator) seem to have problems with some architectural terms. "Gable" is used repeatedly instead of "pediment"; possibly Palladio also did this, but in English "pediment" conveys an idea of a formal architectural element that "gable" does not. Some of the entries are rather short; this is not an academic thesis or a comprehensive gazetteer. The maps indicating the locations of the buildings do only that, there is no further information that would be useful to visitors.
Overall an attractive coffee table book with an intelligent text, but not the definitive work on Palladio.
