Shou appears in many forms, but the three forms illustrated herewith are the most common, not only in Chinese rugs but also as decoration in old porcelain and as embroidered designs on silk.
Signet of David.—Based upon the equilateral triangle and from it have originated many of the Turkish designs. See Star, six-pointed.
Silibik or Apple.—A Kurdish design which bears very little resemblance to the fruit after which it is named. It is usually arranged in perpendicular rows throughout the field.
Sixteen Lucky Squares, see Knot of Destiny.
Snake, see Serpent.
Solomon's Seal.—Built on the right angle triangle and, like the Signet of David, it is found in many of the Turkish and Caucasian fabrics and to it scores of patterns may be traced.
Sparrow.—In India it indicates bumper crops.
