Numerous modifications of a key pattern, often assuming a double triangular form, but with rectangular elements, are found on the exterior of many food bowls. These are variations of a pattern the simplest form of which is shown in [figure 319]. Resolving this figure into two parts by drawing a median line, we find the arrangement is bilaterally symmetrical, the two sides exactly corresponding. Each side consists of a simple key pattern with the shank inclined to the rim of the bowl and a bird emblem at its junction with the other member.
In [figure 320] there is a greater development of this pattern by an elaboration of the key, which is continued in a line resembling a square spiral. There are also dentations on a section of the edge of the lines.
