I'm going to have to put this one away. It may be me, but I find this book very tough going. The writing is turgid and dull, and the author doesn't seem to understand how to carry through a thread of inquiry without skipping essential steps. In other words, she doesn't understand what the elementary reader (who is the target of this book) needs to know in order to follow the discussion. As such, non-sequiturs abound. Again, it may just be that I don't have the patience to plow through this. But a book on 15th cen. art shouldn't demand such patience.
