Mnemosyne — Classical Greek Myth Library

Pontus, the Sea, born of Gaia without a father in Hesiod’s opening, unites with Gaia and begets a first generation of marine powers: Nereus, truth-telling Old Man of the Sea; great Thaumas; proud Phorcys; Ceto of fair cheeks; and Eurybia, whose heart is of adamant. From these spring the named families that people the deep and its edges. Nereus and Doris (daughter of Oceanus) bear the fifty Nereids—Amphitrite, Thetis, Galatea, and the rest—who dwell in the sea and aid or witness heroes. Thaumas and Electra (another Oceanid) bear Iris, swift messenger of the gods, and the Harpies, Aello and Ocypete, storm-winds with girls’ faces. Phorcys and Ceto bear the Graeae (Pemphredo, Enyo, and Deino), old from birth and sharing one eye and one tooth; the Gorgons Stheno, Euryale, and mortal Medusa; and, in the same stretch, the serpent Ladon who guards the Hesperides’ golden apples, and (with further unions) Echidna and her monstrous brood—Orthrus, Cerberus, Hydra, Chimera, Sphinx, and the Nemean Lion—monsters that later labors and heroes confront. Eurybia lies with the Titan Crius and bears Astraeus, Pallas, and Perses, bridging sea-born strength to star-winds and to Hecate’s line. The catalogue is genealogical map rather than single adventure: Pontus’s children organize prophecy (Nereus), message and storm (Thaumas’s line), terror at the world’s rim (Phorcys–Ceto), and the monsters Heracles and Perseus will meet. Where Night bears moral darkness, Pontus bears the living sea and its dangers.
