A symbol of the Divine, a good luck charm, a cosmogram of the world order, a template for fengshui —through the ages, the luoshu, or magic squre of order three, has fascinated people of many different cultures.
In this riveting account of cultural detective work, renowned mathematics educator, Frank J. Swetz relates how he uncovered the previously hidden history of the luoshu, from its Chinese origins, shrouded in legend, through its eventual association with Chinese fortunetelling, Daoism, and fengshui, to its incorporation into Islamic astrology and alchemy and its migration into Kabbalistic lore and other occult traditions of the West.
...an in-depth study of the diverse roles that the luoshu (a 3x3 'magic square' of numbers in a grid, where all rows, columns, and diagonals add up to the same sum) has played in metaphysical and spiritual traditions worldwide. From Chinese fortunetelling to Daoism, and fengshui, to Islamic astrology and Kabbalistic lore, the luoshu has perpetually reappeared throughout global human history. Extensively researched and illustrated with a handful of black-and-white photographs, Legacy of the Luoshu offers a unique glimpse into one aspect of the history of numerology, and is highly recommended especially for mysticism and metaphysical studies shelves.

I found the book very interesting and a joy to read, not least because of the many diagrams and illustrations. What makes this book especially worthwhile, however, is the attention paid to the large variation in cultural meanings, both within China as well as in other countries ... I find in this book a beautiful uncovering of this part of the history of mathematics.

This fascinating book describes the luoshu (i.e. the magic square of order three) from Chinese origins and legends, its role in the development of Chinese mathematical thinking and teaching and its association with the rise of Chinese science and philosophy. It can be recommended to anybody interested in the properties of numbers, roots of number theory and the history of mathematics, as well as Chinese mathematical tradition.
