Classification and analysis of regular geometric patterns with particular reference to textiles

Attention is focused on the range of literature which has contributed to the developing awareness of the theoretical principles governing the geometry of pattern. A means by which textile and other surface patterns can be classified by reference to the symmetry characteristics of their underlying structures is developed, and shown to be an objective, systematic and reproducible means of providing meaningful, standardised descriptions of regular geometric patterns. The potential of the classification system as a worthwhile analytical tool is explored through its application to groups of textile patterns from four distinct cultural settings: traditional Javanese batiks; traditional Sindhi ajraks; Jacquard woven French Silks (Autumn, 1893); Japanese textiles produced during the Edo period (1604-1867) using a variety of patterning techniques. Data are tested to establish firstly, if the patterns from different cultural settings show different symmetry preferences; secondly, if the symmetry preferences associated with a given culture are maintained over the passage of time, in the absence of external pressures for change; thirdly, if techniques of manufacture have any bearing on the symmetry preferences associated with a given culture.
