Shesso, whose qualifications include shamanic practice, labyrinth creation, and service as a teacher and priestess of Wicca, takes readers through the passages of geometric mysteries such as the circle of creation, the influence of the moon, the significance of measurements, magical squares, Templars' codes, and the more widely understood work of Pythagoras. She also explains aspects of the Da Vinci code for those who want to go on the hunt for themselves. Annotation ©2007 Book News, Inc., Portland, OR (booknews.com)
