(), the god of the Mediterranean sea. His name
seems to be connected with πότος, πόντος and ποταμός, according to which he is the god of the fluid element.
(Müller, Proleg. p. 290.) He was a son of Cronos and Rhea (whence he
is called Κρόνιος and by Latin poets Saturnius,Pind. O. 6.48; Verg. A. 5.799.)
He was accordingly a brother of Zeus, Hades, Hera, Hestia and Demeter, and it was determined
by lot that he should rule over the sea. (Hom. Il. 14.156,
15.187, &c.; Hes. Theog, 456.) Like
his brothers and sisters, he was, after his birth, swallowed by his father Cronos, but thrown
up again. (Apollod. 1.1.5, 2.1.) According to others, he was concealed by Rhea, after his birth, among a flock of
lambs, and his mother pretended to have given birth to a young horse, which she gave to Cronos
to devour. A well in the neighbourhood of Mantineia, where this is said to have happened, was
believed, from this circumstance, to have derived the name of the "Lamb's Well," or Arne.
(Paus. 8.8.2.) According to Tzetzes (ad
Lycoph. 644) the nurse of Poseidon bore the name of Arne; when Cronos searched after his
son, Arne is said to have declared that she knew not where he was, and from her the town of
Arne was believed to have received its name. According to others, again, he was brought up by
the Telchines at the request of Rhea. (Diod. 5.55.) In the
earliest poems, Poseidon is described as indeed equal to Zeus in dignity, but weaker. (Hom. Il. 8.210, 15.165, 186, 209; comp. 13.355, Od. 13.148.) Hence we find him angry when Zeus, by haughty words,
attempts to intimidate him; nay, he even threatens his mightier brother, and once he conspired
with Hera and Athena to put him into chains (Hom. Il. 15.176,
&c., 212, &c.; comp. 1.400.); but, on the other hand, we also find him yielding and
submissive to Zeus (8.440). The palace of Poseidon was in the depth of the sea near Aegae in
Euboea (13.21; Od. 5.381), where he kept his horses with
brazen hoofs and golden manes. With these horses he rides in a chariot over the waves of the
sea, which become smooth as he appreaches, and the monsters of the deep recognise him and play
around his chariot. (Il. 13.27, comp. Verg. A. 5.817, &c., 1.147; Apollon. 3.1240,
&c.) Generally he himself put his horses to his chariot, but sometimes he was assisted by
Amphitrite. (Apollon. 1.1158, 4.1325; Eur. Andr. 1011; Verg. A. 5.817.) But although he generally dwelt in the sea, still he also appears in
Olympus in the assembly of the gods. (Hom. Il. 8.440, 13.44, 352, 15.161, 190, 20.13.) Poseidon in conjunction with Apollo is said to have built
the walls of Troy for Laomedon (7.452; Eurip. Androm. 1014),whence Troy
is called Neptunia Pergama (Neptunus and Poseidon being identified, Ov. Fast. 1.525, Heroid. 3.151; comp. Verg. A. 6.810.) Accordingly, although he was otherwise well
disposed towards the Greeks, yet he was jealous of the wall which the Greeks built around
their own ships, and he lamented the inglorious manner in which the walls
erected by himself fell by the hands of the Greeks. (Hom. Il.
12.17, 28, &c.) When Poseidon and Apollo had built
the walls of Troy, Laomedon refused to give them the reward which had been stipulated, and
even dismissed them with threats (21.443); but Poseidon sent a marine monster, which was on
the point of devouring Laomedon's daughter, when it was killed by Heracles. 2.5 § 9.) For
this reason Poseidon like Hera bore an implacable hatred against the Trojans, from which not
even Aeneas was excepted (Hom. Il. 20.293, &c.; comp.
Verg. A. 5.810; Il. 21.459,
24.26, 20.312, &c.), and
took an active part in the war against Troy, in which he sided with the Greeks, sometimes
witnessing the contest as a spectator from the heights of Thrace, and sometimes interfering in
person, assuming the appearance of a mortal hero and encouraging the Greeks, while Zeus
favoured the Trojans. (Il. 13.12, &c., 44, &c., 209, 351, 357,
677, 14.136, 510.) When Zeus permitted the gods to assist whichever party they pleased,
Poseidon joining the Greeks, took part in the war, and caused the earth to tremble; he was
opposed by Apollo, who, however, did not like to fight against his uncle. (Il. 20.23, 34, 57, 67, 21.436, &c.) In the
Odyssey, Poseidon appears
hostile to Odysseus, whom he prevents from returning home in consequence of his having blinded
Polyphemus, a son of Poseidon by the nymph Thoosa. (Hom. Od.
1.20, 68, 5.286,
&c., 366, &c., 423, 11.101, &e., 13.125; Ov. Tr. 1.2.
9.)
Being the ruler of the sea (the Mediterranean), he is described as gathering clouds and
calling forth storms, but at the same he has it in his power to grant a successful voyage and
save those who are in danger, and all other marine divinities are subject to him. As the sea
surrounds and holds the earth, he himself is described as the god who holds the earth
(γαιήοχος), and who has it in his power to shake the
earth (ενοσίχθων, κινητὴρ γᾶς). He was further regarded
as the creator of the horse, and was accordingly believed to have taught men the art of
managing horses by the bridle, and to have been the originator and protector of horse races.
(Hom. Il. 23.307, 584;
Pind. P. 6.50 ; Soph. Oed. Col. 712,
&c.) Hence he was also represented on horseback, or riding in a chariot drawn by two or
four horses, and is designated by the epithets ἵππιος,
ἵππειος, or ἵππιος ἄναξ. (Paus. 1.30.4, 8.25.5, 6.20.8, 8.37.7 ; Eur. Phoen. 1707; comp. Liv. 1.9, where
he is called equester.) In consequence of his connection with the horse,
he was regarded as the friend of charioteers (Pind. O. 1.63,
&c.; Tzetz. ad Lyc. 156), and he even metamorphosed himself into a
horse, for the purpose of deceiving Demeter. The common tradition about Poseidon creating the
horse is as follows : -- when Poseidon and Athena disputed as to which of them should give the
name to the capital of Attica, the gods decided, that it should receive its name from him who
should bestow upon man the most useful gift. Poseidon their created the horse, and Athena
called forth the olive tree, for which the honour was conferred upon her. (Serv. ad Virg. Georg. 1.12.) According to others, however, Poseidon did not create
the horse in Attica, but in Thessaly, where he also gave the famous horses to Peleus. (Lucan,
PPhars. 6.396, &c.; Hom. Il.
23.277; Apollod. 3.13.5.)
The symbol of Poseidon's power was the trident, or a spear with three points, with which he
used to shatter rocks, to call forth or subdue storms, to shake the earth, and the like.
Herodotus (2.50, 4.188) states, that
the name and worship of Poseidon was imported to the Greeks from Libya, but he was probably a
divinity of Pelasgian origin, and originally a personification of the fertilising power of
water, from which the transition to regarding him as the god of the sea was not difficult. It
is a remarkable circumstance that in the legends about this divinity there are many in which
he is said to have disputed the possession of certain countries with other gods. Thus, in
order to take possession of Attica, he thrust his trident into the ground on the acropolis,
where a well of sea-water was thereby called forth; but Athena created the olive tree, and the
two divinities disputed, until the gods assigned Attica to Athena. Poseidon, indignant at
this, caused the country to be inundated. (Hdt. 8.55; Apollod. 3.14.1 ; Paus. 1.24.3,
&c.; Hyg. Fab. 164.) With Athena he also disputed the
possession of Troezene, and at the command of Zeus he shared the place with her. (Paus. 2.30.6 ) With Helios he disputed the sovereignty of Corinth,
which along with the isthmus was adjudged to him, while Helios received the acropolis.
(2.1.6.) With Hera he disputed the possession of Argolis, which was adjudged to the former by
Inachus, Cephissus, and Asterion, in consequence of which Poseidon caused the rivers of these
river-gods to be dried up. (2.15.5, 22.5; Apollod. 2.1.4.)
With Zeus, lastly, he disputed the possession of Aegina, and with Dionysus that of Naxos.
(Plut. Sympos. 9.6.) At one time Delphi belonged to him in common with
Ge, but Apollo gave him Calauria as a compensation for it. (Paus.
2.33.2, 10.5.3; Apollon.
3.1243, with the Schol.) The following legends also deserve to be mentioned. In
conjunction with Zeus he fought against Cronos and the Titans (Apollod. 1.2.1), and in the contest with the Giants he pursued Polybotes across the
sea as far as Cos, and there killed him by throwing the island upon him. (Apollod. 1.6.2; Paus. 1.2.4.) He
further crushed the Centaurs when they were pursued by Heracles, under a mountain in Leucosia,
the island of the Seirens. (Apollod. 2.5.4.) He sued together
with Zeus for the hand of Thetis, but he withdrew when Themis prophesied that the son of
Thetis would be greater than his father. (Apollod. 3.13.5;
Tzetz. ad Lyc. 178.) When Ares had been caught in the wonderful net by
Hephaestus, the latter set him free at the request of Poseidon (Hom.
Od. 8.344, &c.), but Poseidon afterwards brought a charge against Ares before the
Areiopagus, for having killed his son Halirrhothius. (Apollod.
3.14.2.) At the request of Minos, king of Crete, Poseidon caused a bull to rise from
the sea, which the king promised to sacri fice; but when Minos treacherously concealed the
animal among a herd of oxen, the god punished Minos by causing his daughter Pasiphae to fall
in love with the bull. (Apollod. 3.3, &c.) Periclymenus, who
was either a son or a grandson of Poseidon, received from him the power of as-suming various
forms. (1.9.9, 3.6.8.)
Poseidon was married to Amphitrite, by whom he had three children, Triton, Rhode, and
Benthesicyme (Hes. Th. 930; Apollod.
1.4.5, 3.15.4); but he had besides a vast number of children by other
divinities and mortal women. He is mentioned by a variety of surnames, either in allusion to
the many legends related about him, or to his nature as the god of the sea. His worship
extended over all Greece and southern Italy, but he was more especially revered in
Peloponnesus (which is hence called οἰκητήριον
Ποσειδῶνος) and in the Ionic coast towns. The sacrifices offered to him generally
consisted of black and white bulls (Hom. Od. 3.6, Il. 20.404; Pind. O. 13.98; Verg. A. 5.237); but wild boars and rams were also sacrificed to
him. (Hom. Od. 11.130, &c., 23.277; Verg. A. 3.119.) In Argolis bridled horses were thrown into the
well Deine as a sacrifice to him (Paus. 8.7.2), and horse and
chariot races were held in his honour on the Corinthian isthmus. (Pind. N. 5.66, &c.) The Panionia, or the festival of all the lonians near Mycale,
was celebrated in honour of Poseidon. (Hdt. 1.148.) In works of
art, Poseidon may be easily recognised by his attributes, the dolphin, the horse, or the
trident (Paus. 10.36.4), and he was frequently represented in
groups along with Amphitrite, Tritons, Nereids, dolphins, the Dioscuri, Palaemon, Pegasus,
Bellerophontes, Thalassa, Ino, and Galene. (Paus. 2.1.7.) His
figure does not present the majestic calm which characterises his brother Zeus; but as the
state of the sea is varying, so also is the god represented sometimes in violent agitation,
and sometimes in a state of repose. (Hirt, Mythol. Bilderb. i. p. 26.) It
must be observed that the Romans identified Poseidon with their own Neptunus, and that
accordingly the attributes belonging to the former are constantly transferred by the Latin
poets to the latter.
