[Illustration: FIG. 289--Single line with alternate triangles and ovals] [Illustration: FIG. 290--Triangles and quadrilaterals] [Illustration: FIG. 291--Triangle with spurs] In figure 288 the double triangles, one on each side of the encircling band, are so placed that their line of separation is lost, and a single triangle replaces the pair. These are connected by the line surrounding the bowl and there is a dot at the smallest angle. In figure 289 there is a similar design, except that alternating with each triangle, which bears more decoration than that shown in figure 288, there are hourglass figures composed of ovals and triangles. The dots at the apex of that design are replaced by short parallel lines of varying width. The triangles and ovals last considered are arranged symmetrically in relation to a simple band. By a reduction in the intervening spaces these triangles may be brought together and the line disappears. I have found no specimen of design illustrating the simplest form of the resultant motive, but that shown in figure 290 is a new combination comparable with it. The simple triangular decorative design reaches a high degree of complication in figure 290, where a connecting line is absent, and two triangles having their smallest angles facing each other are separated by a lozenge shape figure made up of many parallel lines placed obliquely to the axis of the design. The central part is composed of seven parallel lines, the marginal of which, on two opposite sides, is minutely dentate. The median band is very broad and is relieved by two wavy white lines. The axis of the design on each side is continued into two triangular spurs, rising from a rectangle in the middle of each triangle. This complicated design is the highest development reached by the use of simple triangles. In figure 291, however, we have a simpler form of triangular decoration, in which no element other than the rectangle is employed. In the chaste decoration seen in figure 292 the use of the rectangle is shown combined with the triangle on a simple encircling band. This design is reducible to that shown in figure 290, but is simpler, yet not less effective. In figure 293 there is an aberrant form of design in which the triangle is used in combination with parallel and oblique bands. This form, while one of the simplest in its elements, is effective and characteristic. The triangle predominates in figure 294, but the details are worked out in rectangular patterns, producing the terraced designs so common in all Pueblo decorations. Rectangular figures are more commonly used than the triangular in the decoration of the exterior of the bowls, and their many combinations are often very perplexing to analyze.
