This is one of those books I wish I could give six or even seven starts. This is not only a book about great art; it is itself a beautiful work of art. The care lavished in making this book shows from the beautifully decorated slipcase to the wonderfully textured covers (my kids say they feel furry), to its large format and glorious reproductions. There are many foldouts showing large-scale works in broad sweep and even full-page reproductions of details of works shown in the book.
While the artwork shown is dazzling to the eye and overwhelming to the mind, the articles illuminating the works are first rate as well. One really nice feature of the articles is that there are marginal listings of the plates and figures discussed in each paragraph so it is easy to find text related to the images in which you are interested.
There are two volumes and over 1,300 pages. Volume 1 begins with a brief essay on Florence's prelude to greatness (59 B.C. 0 A.D. 1200). Then the book is organized into sections of varying size: Civic Price and Prosperity (1200 - 1340), An Age of Crisis (1340-1400), Images of a Free Republic (The Early 15th Century), and The Era of Cosimo De' Medici (1430-69). Volume two has: Lorenzo Il Magnifico (1469-92), The End of the Republic (1492-1530, and ends with The Medicean Principate (1530 - c. 1600). Each of these larger sections is organized in the same way - Architecture, then sculpture, and then painting. It is quite fascinating to watch how tastes and techniques evolve over the centuries.
There is also a glossary, bibliography, a section on the photographer and authors, an index and photo credits.
This isn't a book you will likely read from beginning to end. It is almost an ocean you will want to spend time exploring for years in order to take in all that it has to offer. It is almost impossible to not take away something new every time you open its magnificent pages. This is a real treasure for your library. I know is one in mine.
