The fifty daughters of Nereus, the Nereids, are personifications of the smiling, quiet sea.
Nereus is represented with the sceptre and trident; the Nereids are depicted as graceful maidens, lightly clad or naked, riding on tritons and dolphins.
It has been men, tioned that in the Nereids a sexual form occurs which differs structurally from the asexual worms, and was originally placed in a separate genus, Heteronereis; hence the name "Heteronereid" for the sexual worm.
Some of this sculpture has been found; the acroteria are Nereids mounted on sea-horses, and one pediment contained a battle of Greeks and Amazons.
Although the figure of the hero frequently occurs in groups - such as the work of Scopas showing his removal to the island of Leuke by Poseidon and Thetis, escorted by Nereids and Tritons, and the combat over his dead body in the Aeginetan sculptures - no isolated statue or bust can with certainty be identified with him; the statue in the Louvre (from the Villa Borghese), which was thought to have the best claim, is generally taken for Ares or possibly Alexander.
