In Greece all designs featuring peltae follow a quadratic pattern based around the centres of circles. There is a basic formula consisting of circles which are each shifted by one radius. The especially common cruciform pattern arises when a circle is inserted into every second point of the pattern (Fig. 26).

The peltae patterns are somewhat more complicated as generally the circles aren’t drawn with completely solid lines and small semi-circles are added (Fig. 27).
