They were nymphs who personified the situations and sea characteristics. They were daughters of Nereus and Doris Oceanid therefore granddaughters of the Ocean. They were around fifty or 100 according to a different version of the myth.
The Nereids lived on the seabed, in the palace of their father and spent their day swimming and playing with dolphins, or seated on golden thrones or rocks singing and weaving or drying their rich and long hair.
They did not allow any mortal to be contrasted with them in beauty. They had the power to turbulence and calm the sea. In general they were always jubilant about their immortality and accompanied the chariots of marine gods.
One of the famous was Thetis, daughter of Nereus and descendant (granddaughter) of Tithyos. Zeus was charmed by her looks, but she rejected him. Themis, the goddess revealed then that Thetis would bear a son who would be stronger than his father. Fearing of losing power, Zeus gave Thetis a mortal husband, Peleus.
