Why is the number seven lucky - even holy - in almost every culture? Why do we speak of the four corners of the earth? Why do cats have nine lives (except in Iran, where they have seven)? From literature to folklore to private superstitions, numbers play a conspicuous role in our daily lives. In The Mystery of Numbers Annemarie Schimmel conducts an illuminating tour of the mysteries attributed to numbers over the centuries. She covers the origins of numbers, the symbolism of numbers, the source of this symbolism, and examines individual numbers from one to ten thousand. Using examples ranging from the Bible to Shakespeare, this engaging account uncovers the roots of a phenomenon we all feel every Friday the thirteenth.
