Nereus, in Greek Mythology, was the eldest son of Pontus (the Sea) and Gaia (the Earth), a Titan who (with Doris) fathered the Nereids, with whom Nereus lived in the Aegean Sea. In the Iliad the Old Man of the Sea (άλίός γέρών) is the father
of Nereids, though Nereus is not directly named. He was one of the manifestations of the Old Man of the Sea, never more so than when he was described, like Proteus, as a shapeshifter with the power of prophecy, who would aid heroes such as Heracles who managed to catch him even as he changed shapes. Nereus and Proteus ("first") seem to be two
manifestations of the god of the sea who was supplanted by Poseidon when Zeus overthrew Cronus.
The earliest poet to link Nereus with the labours of Heracles was Pherekydes, according to a scholion on Apollonius of Rhodes.
During the course of the fifth century BCE, Nereus was gradually replaced by Triton, who does not appear in Homer, in the imagery of the struggle between Heracles and the sea-god who had
to be restrained in order to deliver his information that was employed by the vase-painters, independent of any literary testimony.
Nereus was known for his truthfulness and virtue:
- "But Pontos, the great sea, was father of truthful Nereus who tells no lies, eldest of his sons.
They call him the Old Gentleman because he is trustworthy, and gentle, and never forgetful of what is right, but the thoughts
of his mind are mild and righteous." — Hesiod, Theogony 233
The Attic vase-painters showed the draped torso of Nereus issuing from a long coiling scaly fishlike
tail Bearded Nereus generally wields a staff of authority. He was also shown in scenes depicting the flight of the Nereides
as Peleus wrestled their sister Thetis.
In Aelian's natural history, written in the early third century of the Common Era, Nereus was also the father of a watery consort of Aphrodite named Nerites who was transformed into "a shellfish with a spiral shell, small in size but of surpassing
Nereus was father to Thetis, one of the Nereids, who in turn was mother to the great Greek hero Achilles
Marriages and children
It is very probable that Herod had more children, especially with the last wives, and also that he
had more daughters, as female births at that time were often not recorded.
