Fig. 315—Key pattern; rectangle and triangles
Fig. 316—Rectangle and crook
For some unknown reason the majority of the simple designs on the exterior of food bowls from Tusayan are rectangular, triangular, or linear in their character. Many can be reduced to simple or multiple lines. Others were suggested by plaited ware.
Fig. 317—Crook and tail feathers
In [figure 312] is found one of the simplest of rectangular designs, a simple band, key pattern in form, at one end, with a reentrant square depression at the opposite extremity. In [figure 313] is an equally simple terrace pattern with stepped figures at the ends and in the middle. These forms are common decorative elements on the exterior of jars and vases, where they occur in many combinations, all of which are reducible to these types. The simplest form of the key pattern is shown in [figure 314], and in [figure 315] there is a second modification of the same design a little more complicated. This becomes somewhat changed in [figure 316], not only by the modifications of the two extremities, but also by the addition of a median geometric figure.
