Still more complex are a number of borders embroidered in colored yarn. In these we may distinguish between the rhythm of form and of color (fig. 38). The arrangement is one combining symmetry with rhythmic complexity. On one of these strips (fig. 38 a) some of the rectangles with rhombic checkerwork have a white background; in these there are two rows of blue or purple diamonds at each end and two rows of red diamonds in the centre (design 1). Other rectangles have a yellow background with red diamonds at the sides and blue ones in the middle (design 2). Besides these there is one with red background and black diamonds (design 3). The colors of the crosses are irregularly arranged. There are four with predominating red and white (design 4) and others with predominating yellow and blue (design 5). The most symmetrical arrangement of this strip requires a yellow rectangle in the middle of the front. One end of the stripe, as shown in the illustration, has three short blue bars on a red background (design 6). The peculiar cut at this end fits into a corresponding cut at the other end and shows that the stripe as it is has been taken from a garment. The general impression of the design is that the rhythm and symmetry of the crosses is subordinated to the symmetry of the rectangles. For this reason I have placed the crosses in the following arrangement in the upper line, the rectangles in the lower line. Crosses 4 5 5 5 4 5 4 4 5 4 6 Rectangles 2 1 1 2 1 1 2 1 3 1 Front Back The embroidery on figure 38 b consists of four distinct elements; a flower with leaves on each side (design 1); one branch with curved leaves (design 2); one branch with terminal flowers (design 3). Besides these there is one other element which occurs only once on the back of the coat. It is marked design 4. The embroidered stripe is not sewed symmetrically to the coat but has evidently been placed in such a way that the arrangement in the front of the coat corresponds to the sequence:— 2 3 2 1 _3_ 1 2 3 2 while the back is occupied by three designs (3). The small design (4) is found on the back. The whole arrangement of the small designs on the back being 2 2 4 2 Another specimen (fig. 38 c) consists of a double leaf design on a plain background alternating with another design consisting of three crosses. This pair of designs occurs in regular succession five times, but under the left arm it is interrupted by the two patterns shown on the right hand side of the figure. [Illustration: Fig. 38.
