Now the high priest’s robe is the symbol of the world of sense. The seven planets are represented by the five stones and the two carbuncles, for Saturn and the Moon. The former is southern, and moist, and earthy, and heavy; the latter aerial, whence she is called by some Artemis, as if Aerotomos (cutting the air); and the air is cloudy. And co-operating as they did in the production of things here below, those that by Divine Providence are set over the planets are rightly represented as placed on the breast and shoulders; and by them was the work of creation, the first week. And the breast is the seat of the heart and soul.
