"Mathematics + Art: A Cultural History" by Lynn Gamwell is beautiful book. The format is large, the printing and the paper are high quality. It is pleasurable to leaf through it (but it is also very heavy --- the cover is slick, I almost dropped it, wear shoes while carrying). My favorite illustration is the last one in the book, before the acknowledgements: the root system of E8. That is available on the Internet, of course, but I wouldn't have thought to look for it had it not been in the book. The illustrations for the modern era are necessarily limited, else the book would go on for several more volumes. I think that the cultural aspect of the book begins to break down in the 20th century, somehow. There is math, there are computers, the whole way of thinking about creativity has shifted. Hilarie
