This was a thoroughly readable overview of Michelangelo's life and work. It had a good balance of details about the artist's life (including sizable quotes from his letters and poetry, and Vasari and Condivi's contemporary biographies), historical background and context (enough to understand what was going on, not so much as to be overwhelming), and critical analysis and description of the art. I LOVED how it included color photos of everything being discussed, right next to the text where it was mentioned - nothing left to the reader's memory or previous knowledge.
It is interesting to compare this book to somewhat older texts in terms of interpretation of the art and Michelangelo's intentions in creating it. Hughes is reluctant to give any definitive statements. He puts a lot of emphasis on historical attitudes and views of the work, and is skeptical that we can assume to find any hidden "meanings" based on our modern perspective. A good example is Michelangelo's use of non-finito, or lack of finish on many sculptures. This adds a lot of expressive power, and we are used to seeing intentional use of the technique - but how likely is it that Michelangelo would have left these statues unfinished on purpose, given the Renaissance views of art?
Sometimes I think Hughes takes this position too far, but he makes good points that are useful as a counterbalance to other writers who can overstate their subjective interpretations.
