Numbers permeate every aspect of our lives, very little happens without a basic ability to manipulate the simple whole numbers we all take for granted. Beautifully illustrated with old engravings as well as contemporary imagery, Sacred Number introduces basic counting systems, significant numbers from major religious texts, the importance of astronomy, geometry, and music to number quality, how numbers affect architecture. Lundy explains why the ideas of Pythagoras still resonate, and she profiles each number from one to ten to show its distinct qualities: why, for example, the golden section is associated with five, and seven with the Virgin Mary.
