An article in this week’s *Science News* describes mathematical decorations known as sangakus—visual representations of geometric proofs that appear in Japanese temples. The article shows a sample theorem, but I find particularly striking is the use of mathematical representations for their aesthetic impact—presumably both visual and intellectual.

Tony Rothman presents several high-resolution images of sangaku on his web page, and he has also coauthored the forthcoming *Sacred Mathematics* with Hidetoshi Fukagawa. With any luck, that volume will shed additional light on the topic and offer a much more complete perspective on the intersection of mathematics and aesthetics in a seemingly unusual venue.

(Rothman, BTW, has authored several books: including The provocative *Doubt and Certainty*, which looks at epistemological questions in science from both Eastern and Western perspectives, and

the more light-hearted *Everything’s Relative: And Other Fables from Science and Technology*, which presents a laundry-list of oddities from the history of science. At least, those are two of his that happen to grace my shelves.)
