The myths of Nereus
2 myths, each traced to its primary text and corpus sources.
The Birth of Nereus
Gaia brought forth Pontos, the sea, without prior intercourse. Pontos and Gaia then produced Nereus, one of the ancient powers of the sea. Nereus belonged to the first generation of marine beings descended from earth and sea. His birth followed Gaia’s emergence and her creation of Pontos, and placed him among the earliest sea powers.
Hesiod described Nereus as gentle, truthful, and knowing. He did not lie, forget ordinances, or give false judgement. He knew just and gentle counsels, and he was unerring. His name carried associations with truth and with not forgetting. He stood opposite forces such as Discord and Bad Governance. In this role, he joined straight justice with gentle conduct, sound counsel, and reliable judgement.
Nereus was also known as the wise and unerring Old Man of the Sea. Prophetic knowledge was attributed to him, and this knowledge gave him authority when others sought guidance. He later fathered the Nereids with Doris. The Nereids were sea nymphs descended from their union. Among them were Amphitrite, Thetis, and Galatea. Thetis became the mother of Achilles, while Galatea was loved by the Cyclops Polyphemus.

Nereus and Doris
Nereus married Doris, the daughter of Oceanus, and together they became the parents of the Nereids, the sea nymphs. They were usually said to number fifty. The Nereids lived with their father in a cave at the bottom of the sea. Nereus was associated chiefly with the Aegean Sea and was represented as an old man with azure hair.
Nereus was known for wisdom, truth, and justice. He was called the unerring Old Man of the Sea, and he possessed the gift of foretelling future events. The Nereids were shown with him, dancing around him in chorus. They became his daughters and attendants.
Among the most celebrated Nereids were Amphitrite, Thetis, and Galatea. Amphitrite became the wife of Poseidon and the mother of Triton. Poseidon came to court her riding on a dolphin. After winning her, he placed the dolphin among the stars as a reward.
Thetis became the mother of Achilles. Galatea was loved by the Cyclops Polyphemus. The Nereids also helped Jason after his quest for the Golden Fleece. They guided the Argo through the Clashing Rocks on its return, and, according to Apollonius of Rhodes, Thetis led them in this task. In another account, Poseidon acted against Ethiopia after Cassiopeia claimed to be more beautiful than the Nereids. He sent a flood and a sea monster, and Andromeda was offered as a sacrifice until Perseus came to her rescue.
