The decoration in [figure 305] consists of rectangular and triangular figures, the latter so closely approximated as to leave zigzag lines in white. These lines are simply highly modified breaks in bands which join in other designs, and lead by comparison to the so-called "line of life" which many of these figures illustrate.
