A very appealing book. It deals with the analysis of repetitive patterns in decorative art as a means of classifying designs. A collaboration by an anthropologist (Washburn, U. Rochester) and a mathematician (Crowe, U. of Wisc.), it makes only the gentlest use of math/geometry, the principles of which are presented. These allow a discussion of color symmetry, one- and two-dimensional patterns, and finite design. History and problems of classification are covered. An important work.
