(26) Other hieroglyphics seen in connection with Isis are no less curious than those already described, but it is impossible to enumerate all, for many symbols were used interchangeably by the Egyptian Hermetists. The goddess often wore upon her head a hat made of cypress branches, to signify mourning for her dead husband and also for the physical death which she caused every creature to undergo in order to receive a new life in posterity or a periodic resurrection. The head of Isis is sometimes ornamented with a crown of gold or a garland of olive leaves, as conspicuous marks of her sovereignty as queen of the world and mistress of the entire universe. The crown of gold signifies also the aurific unctuosity or sulphurous fatness of the solar and vital fires which she dispenses to every individual by a continual circulation of the elements, this circulation being symbolized by the musical rattle which she carries in her hand. This sistrum is also the yonic symbol of purity.
