The early Greeks, with their extraordinary power of personifying all and every attribute of Nature, gave a distinct personality to those mighty wonders of the deep, which, in all ages, have afforded matter of speculation to educated and uneducated alike. Among these personifications we find Thaumas, Phorcys, and their sister Ceto, who were the offspring of Pontus.

Thaumas (whose name signifies Wonder) typifies that peculiar, translucent condition of the surface of the sea when it reflects, mirror-like, various images, and appears to hold in its transparent embrace the flaming stars and illuminated cities, which are so frequently reflected on its glassy bosom.

Thaumas married the lovely Electra (whose name signifies the sparkling light produced by electricity), daughter of Oceanus. Her amber-coloured hair was of such rare beauty that none of her fair-haired sisters could compare with her, and when she wept, her tears, being too precious to be lost, formed drops of shining amber.

Phorcys and Ceto personified more especially the hidden perils and terrors of the ocean. They were the parents of the Gorgons, the Græa, and the Dragon which guarded the golden apples of the Hesperides.
