Query: Excellence at its best

I must say that this is the best comprehensive art historical book that I have ever come across. It's actually a book that I have been reading more for pleasure than for study, and I recommend it to anyone who is even remotely interested in painting, architecture or any artistic elements. The photos are fantastically sharp and accurately placed near if not next to the corresponding text and in no way is it difficult to read or understand. The author writes as if he were explaining it to the reader for the first time, but it does not feel elementary in any way. An excellent book with fantastic promise. I have learned much with very little effort - the best way to study!!
