In connection with Poseidon it may be convenient to mention here other divinities and beings with marine associations—such as Okeanos, Nereus, and Triton, and the Nereids or sea-nymphs, daughters of Nereus, with the more rarely occurring Naiads. Of these the name of Okeanos occurs but once, on the François vase. The figure itself has disappeared, but the marine monster on which he rides to the wedding of Peleus and Thetis, and the inscription, remain. =Nereus= appears as a single figure, with fish-tail and trident,[158] but is most frequently met with in connection with the capture of his daughter Thetis by Peleus, either as a spectator or receiving the news from a Nereid.[159] He also watches the contest of Herakles with Triton,[160] himself encountering the hero in some cases.[161] On one vase Herakles has seized his trident and threatens him by making havoc of his belongings.[162] He appears at Herakles’ combat with Kyknos,[163] and at his apotheosis,[164] and also offers a crown to Achilles.[165] In one case he is found in Dionysos’ company.[166] With his daughter Doris he watches the pursuit of another Nereid by Poseidon.[167] =Triton= is found as a single figure,[168] and (chiefly on B.F. vases) engaged in a struggle with Herakles.[169] He also carries Theseus through the sea to Poseidon,[170] and watches the flight of Phrixos and Helle over the sea.[171] The group of deities represented by Ino and Leukothea, Palaimon, Melikertes, and Glaukos appear in isolated instances,[172] as do Proteus[173] and Skylla[174]—the latter as single figures, without reference to their connection with the _Odyssey_. A monstrous unidentified figure, with wings and a serpentine fish-tail, which may be a sea-deity (in one case feminine), is found on some early Corinthian vases[175]; possibly Palaimon is intended. =The Nereids=, who are often distinctively named, are sometimes found in groups,[176] especially watching the seizure of Thetis or bearing the news to Nereus[177]; or, again, carrying the armour of Achilles over the sea and presenting it to him.[178] On one vase they mourn over the dead Achilles.[179] They are also present at the reception of Theseus,[180] the contest of Herakles and Triton,[181] and with Europa on the bull.[182] Kymothea offers a parting cup to Achilles[183]; the Naiads, who are similar beings, present to Perseus the cap, sword, shoes, and wallet.[184] They are also found grouped with various deities,[185] and even one in the under-world.[186] Thetis appears once as a single figure, accompanied by dolphins[187]; for her capture by Peleus and relations with Achilles, see p. 120 ff. * * * * *
