Poseidon (; Ancient Greek: Ποσειδῶν, romanised: Poseidôn) is one of the twelve Olympians in ancient Greek religion and mythology, presiding over the sea, storms, earthquakes and horses. He was the protector of seafarers and the guardian of many Hellenic cities and colonies. In pre-Olympian Bronze Age Greece, Poseidon was venerated as a chief deity at Pylos and Thebes, with the cult title "earth shaker"; in the myths of isolated Arcadia, he is related to Demeter and Despoina and was venerated as a horse, and as a god of the waters. Poseidon maintained both associations among most Greeks: he was regarded as the tamer or father of horses, who, with a strike of his trident, created springs (the terms for horses and springs are related in the Greek language). His Roman equivalent is Neptune.
Homer reports that Poseidon became lord of the sea when, following the overthrow of his father Cronus, the world was divided by lot among Cronus' three sons; Zeus received the sky, Hades the underworld, and Poseidon the sea, with the Earth and Mount Olympus belonging to all three. In Plato's Timaeus and Critias, the legendary island of Atlantis was Poseidon's domain. In Homer's Iliad, Poseidon supports the Greeks against the Trojans during the Trojan War. In the Odyssey, during the sea-voyage from Troy back home to Ithaca, the Greek hero Odysseus provokes Poseidon's fury by blinding his son, the Cyclops Polyphemus, resulting in Poseidon punishing him with storms, causing the complete loss of his ship and numerous of his companions, and delaying his return by ten years.
According to legend, Athena became the patron goddess of the city of Athens after a competition with Poseidon, though he remained on the Acropolis in the form of his surrogate, Erechtheus. After the fight, Poseidon sent a monstrous flood to the Attic plain to punish the Athenians for not choosing him. Other myths describe similar contests between Poseidon and another deity for the patronage of a city.

Etymology
The earliest attested occurrence of the god's name, written in Linear B, is 𐀡𐀮𐀅𐀃 Po-se-da-o or 𐀡𐀮𐀅𐀺𐀚 Po-se-da-wo-ne, which correspond to Ποσειδάων (Poseidaōn) and Ποσειδάϝoνος (Poseidawonos) in Mycenean Greek; in Homeric Greek, it appears as Ποσιδάων (Posidaōn); in Aeolic, as Ποτε(ι)δάων (Pote(i)daōn); in Doric, as Ποτειδάν (Poteidan) and Ποτειδᾶς (Poteidas); in Arcadic, as Ποσoιδᾱν (Posoidan). In inscriptions with Laconic style from Tainaron, Helos and Thuria the god's name is rendered as Ποὁιδάν (Pohoidan), indicating that the Dorians took the name from the older population. The form Ποτειδάϝων (Poteidawōn) appears in Corinth.
The origins of the name "Poseidon" are unclear and the possible etymologies are contradictive among the scholars. One theory breaks it down into an element meaning "husband" or "lord" (Greek πόσις (posis), from PIE *pótis) and another element meaning "earth" (δᾶ (da), Doric for γῆ (gē)), producing something like lord or spouse of Da, i.e. of the earth; this would link him with Demeter, "Earth-mother". Burkert finds that "the second element δᾶ- remains hopelessly ambiguous" and finds a "husband of Earth" reading "quite impossible to prove". According to Beekes in Etymological Dictionary of Greek, "there is no indication that δᾶ means 'earth'", although the root da appears in the Linear B inscription E-ne-si-da-o-ne, "earth-shaker".
Another theory interprets the second element as related to the (presumed) Doric word *δᾶϝον dâwon, "water", Proto-Indo-European *dah₂- "water" or *dʰenh₂- "to run, flow", Sanskrit दन् dā́-nu- "fluid, drop, dew" and names of rivers such as Danube (< *Danuvius) or Don. This would make *Posei-dawōn into the master of waters.
Plato in his dialogue Cratylus gives two traditional etymologies: either the sea restrained Poseidon when walking as a "foot-bond" (ποσίδεσμον), or he "knew many things" (πολλά εἰδότος or πολλά εἰδῶν).
Beekes suggests that the word has probably a Pre-Greek origin. The original form was probably the Mycenean Greek Ποτ(σ)ειδάϝων (Pot(s)eidawōn). "The intervocalic aspiration suggests a Pre-Greek (Pelasgian) origin rather than an Indo-European one".
Bronze Age Greece
Linear B (Mycenean Greek) inscriptions
If surviving Linear B clay tablets can be trusted, the
names po-se-da-wo-ne and Po-se-da-o ("Poseidon") occur with greater frequency than does di-u-ja ("Zeus"). A feminine variant, po-se-de-ia, is also found, indicating a lost consort goddess, in effect the precursor of Amphitrite.
Poseidon was the chief god at Pylos. The title wa-na-ka appears in the inscriptions. Poseidon was identified with the title wanax from the Homeric era to classical Greece. The title didn't mean only king, but also protector. Wanax had chthonic aspects, and he was closely associated with Poseidon, who had the title "Lord of the Underworld". The chthonic nature of Poseidon is also indicated by his title E-ne-si-da-o-ne (Earth-shaker) in Mycenean Knossos and Pylos. Through Homer the epithet was also used in classical Greece. (Ennosigaios, ennosidas).
Po-tini-ja (potnia: lady or mistress) was the chief goddess at Pylos and she was closely associated with Poseidon. She was the Mycenean goddess of nature and Poseidon—Wanax is one from the gods who may be considered her "male paredros". The earth shaker received offerings in the cave of the goddess of childbirth Eileithyia at Amnisos in Crete. Poseidon is allied with Potnia and the divine child.
Wa-na-ssa (anassa: queen or lady) appears in the inscriptions usually in plural. (Wa-na-ssoi). The dual number is common in Indo-European grammar (usually for chthonic deities like the Erinyes) and the duality was used for Demeter and Persephone in classical Greece (the double named goddesses). Potnia and wanassa refer to identical deities or two aspects of the same deity.
E-ri-nu (Erinys) is attested in the inscriptions. In some ancient cults Erinys is related to Poseidon and her name is an epithet of Demeter.
It is possible that Demeter appears as Da-ma-te in a Linear B inscription (PN EN 609), however the interpretation is still under dispute. Si-to Po-tini-ja is probably related with Demeter as goddess of grain.
Mycenean cult
During the Mycenean period, the ancestral male gods of the Myceneans were probably not represented in human forms, and the information given by the tablets found at Pylos and Knossos is insufficient. Poseidon was the chief deity at Pylos and Thebes. He is identified with Anax and he carried the title "Master of the Underworld". Anax had probably a cult associated with the protection of the palace. In Acrocorinth he was worshipped as Poseidon Anax during the Mycenean age. In the city, there was the famous spring Peirene, which in a myth is related to the winged horse Pegasus. In Attica there was a cult of Anax heroes who was connected to Poseidon. A cult title of Poseidon was "earth-shaker" and in Knossos he was worshipped together with the goddess Eleithyia who was related to the annual birth of the divine child. Potnia was the Mycenean goddess of nature and she was the consort of Poseidon at Pylos. She is mentioned together with bucrania in decorated jugs and he was associated with the animals and especially to the bull. In Athens, Poseidon was an inland god who created the salt-sea Erecthēιs (Ερεχθηίς), "sea of Erechtheus". In Acropolis his cult was superimposed on the cult of the local ancestral figure Erechtheus. In Athens and Asine he was worshipped in the house of the king during the Mycenean period. The bull was the favourite animal for sacrifices and it seems that horses were rarely used during the burial of the Mycenean leaders.
Arcadian myths
In the Arcadian myths, Poseidon is related to Demeter and Despoina and he was worshipped with the surname Hippios in many Arcadian cities. At Thelpusa and Phigalia there were sister worships which are very important for the study of primitive religions. In these cults Demeter and Poseidon were chthonic divinities of the underworld.
Near Thelpusa the river Ladon descended to the sanctuary of Demeter Erinys (Demeter-Fury). During her wandering in search of her daughter Demeter changed into a mare to avoid Poseidon. Poseidon took the form of a stallion and after their mating she gave birth to a daughter whose name was not allowed to be told to the uninitiated and a horse called Arion (very swift). Her daughter obviously had the shape of a mare too. At first Demeter became angry and she was given the surname Erinys (fury) by the Thelpusians. The Erinyes were deities of vengeance, and Erinys had a similar function with the goddess Dike (Justice). In the very old myth of Thelpusa Demeter-Erinys and Poseidon are divinities of the underworld in a pre-mythic period. Poseidon appears as a horse. In Greek folklore the horses had chthonic associations and it was believed that they could create springs. In European folklore the water-creatures or water-spirits appear with the shape of a horse or a bull. In Greece the river god Acheloos is represented like a bull or a man-bull. Many people when sacrificed to Demeter should make a premilinary sacrifice to Acheloos
At Phigalia Demeter had a sanctuary in a cavern and she was given the surname Melaina (black). The goddess was related to the black underworld. In a similar myth Poseidon appears as a horse and Demeter gives birth to a daughter whose name was not allowed to be told to the unitiated (At Lycosura her daughter was called Despoina). Demeter, angry with Poseidon, put on a black dressing and shut herself in the cavern. When the fruits of the earth were perished, Zeus sent the Moirai to Demeter who listened to them and put aside her wrath. In this cult we have traces of a very old cult of Demeter and Poseidon as deities of the underworld.
In another Arcadian myth when Rhea had given birth to Poseidon, she told Cronus that she had given birth to a horse, and gave him a foal to swallow instead of the child. In the Homeric Hymn to Demeter the goddess puts on a dark mourning robe around her shoulders as a sign of her sorrow. Demeter's mare-form was worshipped into historical times. The xoanon of Melaina at Phigalia shows how the local cult interpreted her, as goddess of nature. A Medusa type with a horse's head with snaky hair, holding a dove and a dolphin, probably representing her power over air and water.
Boeotian myths
The myth of Poseidon appearing as a horse and mating with Demeter was not localized in Arcadia. At Haliartos in Boeotia near Thebes Poseidon appears as stallion. He mates with Erinys near the spring of Tilpousa and she gives birth to the faboulous horse Arion. At Tilpusa we have a very old cult of the chthonic deities Erinys and Poseidon. The water-god Poseidon appears as a horse which seems to represent the water-spirit and Erinys is probably the personification of a revenging earth-spirit. From earlier times at Delphi Poseidon was joined in a religious union with the earth-goddess Ge. She is represented as a snake which is a form of the earth-spirit.
In Hesiod's Theogony Poseidon once slept with the monstrous Medusa near the mountain Helikon. She conceived the winged horse Pegasus who sprang out of her body when Perseus cut off her head. Pegasus stuck the ground with his hoof and created the famous spring Hippocrene near Helikon.
Praxidicai were female deities of judicial punishment worshipped in the region of Haliartos in the historical times. Their origin is probably the same with Erinys. Their images depicted only the heads of the goddesses probably a representation of the earth goddess emerging from the ground. Praxidice is an epithet of Persephone in the Orphic Hymns. Persephone is sometimes depicted with her head emerging from the ground.
Origins
During the Mycenean period Poseidon was worshipped in several regions in Greece. At Pylos and some other cities he was a god of the underworld (Lord of the Underworld) and his cult was related to the protection of the palace. He carried the title anax, king or protector. His consort potnia, lady or mistress, was the Mycenean goddess of nature. Her main aspects were birth and vegetation. Poseidon had the title "Enesidaon" (earth-shaker) and in Crete he was associated with the goddess of childbirth Eleithyia. Through Homer the Mycenean titles were also used in classical Greece with similar meaning. He was identified with anax and he carried the epithets "Ennosigaios" and "Ennosidas" (earth-shaker). Potnia was a title which accompanied female goddesses. The goddess of nature survived in the Eleusinian cult, where the following words were uttered: "Mighty Potnia bore a strong son". In the heavily sea-dependent Mycenaean culture, there is not sufficient evidence that Poseidon was connected with the sea; it is unclear whether "Posedeia" was a sea-goddess. The Greek invaders came from far inland and they were not familiarized with the sea.
In the primitive Boeotian and Arcadian myths Poseidon, the god of the underworld, appears as a horse and he is mating with the earth goddess. The earth goddess is called Erinys or Demeter and she gives birth to the fabulous horse Arion and the unnamed daughter Despoina. The horse represents the divine spirit (numen) and is related to the liquid element and the underworld. In Greek folklore the horse is associated with the underworld and it was believed that it had the ability to create springs. In the European folklore the water-spirit appears with the shape of a horse or a bull. In Greece the river god Acheloos is represented as a bull or a man-bull. Burkert suggests that the Hellenic cult of Poseidon as a horse god may be connected to the introduction of the horse and war-chariot from Anatolia to Greece around 1600 BC.
In the Boeotian myth, Poseidon is the water-god and Erinys is a goddess of the underworld.
She is probably the personification of a revenging earth spirit and it seems that she had a similar function with the goddess Dike (Justice). At the spring "Tilpousa" she gives birth to Arion. In the Arcadian myth Poseidon Hippios (horse) is mating with the mare-Demeter. At Thelpousa Demeter-Erinys gives birth to Arion and to an unnamable daughter who has the shape of a mare. In some neighbour cults the daughter was called Despoina (mistress). The theriomorphic form of gods seems to be local in Arcadia in an old religion associated with xoana.
Cult
I begin to sing about Poseidon, the great god,
mover of the earth and fruitless sea
god of the deep who is also lord of Helicon and wide Aegae.
A two-fold office the gods allotted you,
O Shaker of the Earth, to be a tamer of horses
and a saviour of ships!
Hail, Poseidon, Holder of the Earth, dark-haired lord!
O blessed one, be kindly in heart
and help those who voyage in ships!
(Homeric Hymn to Poseidon)
The worship of Poseidon was extended all over Greece and southern Italy, but he was specially honoured in the Peloponnese which is called "the residence of Poseidon" and in the Ionic cities. The significance of his cult is indicated by the names of cities like Poteidaia in the Chalkidiki peninsula and Poseidonia (Paestum), a Greek colony in Italy. Poseidion is a frequent Greek placename along coastlines and the name of a Greek colony at the Syrian coast.
In Ionia his cult was introduced by Achaean colonists from Greece in the 11th century BC. Traditionally the colonists came from Pylos where Poseidon was the principal god of the city. The god had a famous temple near the mountain Mycale. The month Poseidaon is the month of the winter-storms. The name of the month was used in Ionic territories, in Athens, in the islands of the Aegean and in the cities of Asia Minor. At Lesbos and Epidauros the month was called Poseidios. During this month Poseidon was worshipped as the "master of the sea" in a bright cult.
Poseidon was a major civic god of several cities: in Athens, he was second only to Athena in importance, while in Corinth and many cities of Ionia and Magna Graecia he was the chief god of the polis. Many fests of Poseidon included athletic competitions and horseracing.
Epithets and attributes
Poseidon had a variety of roles, duties and attributes. He is a separate deity from the oldest Greek god of the sea Pontus. In Athens his name is superimposed οn the name of the non-Greek god Erechtheus (Ἑρεχθεύς, Poseidon Erechtheus).
In the Iliad, he is the lord of the sea and his golden palace is built in Aegai, in the depth of the sea. His significance is indicated by his titles Eurykreion (Εὐρυκρείων), "wide-ruling", an epithet also applied to Agamemnon and Helikonios anax (Ἑλικώνιος ἄναξ), "lord of Helicon or Helike". In Helike of Achaia he was especially honoured. Anax is identified in Mycenaean Greek (Linear B) as wa-na-ka. Aeschylus uses also the epithet anax and Pindar the epithet Eurymedon (Εὐρυμέδων), "widely ruling".
Some of the epithets (or adjectives) applied to him like Enosigaios (Ἐνοσίγαιος), Enosichthon (Ἐνοσίχθων) (Homer) and Ennosidas (Ἐννοσίδας) (Pindar), mean "earth shaker". These epithets indicate his chthonic nature, and have an older evidence of use, as it is identified in Linear B as 𐀁𐀚𐀯𐀅𐀃𐀚, E-ne-si-da-o-ne. Other epithets that relate him with earthquakes are Gaieochos (Γαιήοχος) and Seisichthon (Σεισίχθων)
The god who causes the earthquakes is also the protector against them, and he had the epithets Themeliouchos (Θεμελιούχος), "upholding the foundations", Asphaleios (Ἀσφάλειος), "securer, protector", with a temple at Tainaron. Pausanias describes a sanctuary of Poseidon near Sparta beside the shrine of Alcon, where he had the surname Domatites (Δωματίτης), "of the house"
He also had the epithet Gaeeochus (Γαιήοχος), meaning "holder of the earth".
Homer uses for Poseidon the title Kyanochaites (Κυανοχαίτης), "dark-haired, dark blue of the sea". Epithets like Pelagios (Πελάγιος) "of the open sea", Aegeus (Αἰγαίος), "of the high sea" in the town of Aegae in Euboea, where he had a magnificent temple upon a hill, Pontomedon (Ποντομέδων)," lord of the sea" (Pindar, Aeschylus) and Kymothales (Κυμοθαλής), "abounding with waves", indicate that Poseidon was regarded as holding sway over the sea. Other epithets that relate him with the sea are, Porthmios (Πόρθμιος), "of strait, narrow sea" at Karpathos, Epactaeus (Ἐπακταῖος) "god worshipped on the coast", in Samos, Alidoupos, (Ἀλίδουπος) "sea resounding". The master of the sea who can cause devastating storms is also the protector of seafarers and he was given the epithet sōtēr (Σωτήρ), "savior".
Festivals
Many festivals all over Greece, in the Ionic cities and in Italy, were celebrated in honour of Poseidon.
Corinth: The Panhellenic Isthmian Games were celebrated in honour of Poseidon. His sanctuary is to be seen in the context of the position of Corinth controlling the sea. The festival included athletic and musical competitions and horseracing. Traditionally the games were established in the Bronze Age over the dead prince Palaimon.
Athens: Poseidon had a festival in the month Poseidaon in the Attic calendar. He was worshipped as the "master of the sea".
Athens: Haloa was a festival of vegetation. The wine-festival Protrygaia belonged to Dionysus and to Poseidon as a god of vegetation.
Mycale in Ionia: Mycale was a promontory, between Samos and Miletus. The representatives of twelve cities (dodekapolis) celebrated the Panionia (of all the Ionians), a festival of Poseidon Helikonios. Traditionally the first settlers landed in this place. The temple became the meeting place of the Ionian League). Homer describes the sacrifice of a bull to Poseidon, during the festival.
Ephesus in Ionia. The relation of Poseidon with the bull is stronger in Ionia. The festival Tauria was celebrated in honour of Poseidon Taureios and the capbearers were called tauroi (bulls).
Kalaureia: Poseidon was the patron god of the Amphictiony of Kalaureia. The festival was celebrated in honour of the god. The famous temple was the meeting place of the representatives of the members (Amphiktiones).
Tainaron: The famous festival Tainaria was celebrated in honour of Poseidon. The participants were called Tainarioi. The sacred sanctuary of the god was built in a cave in the Tainaron peninsula. A filial cult existed in Sparta.
Onchestos in Boeotia. Poseidon had a famous temple praised by Homer in the Catalogue of Ships, with the surname Helikonios. It became the place of meeting of the second Boeotian league. The peculiar fest included horseracing. At the beginning of the race the charioteers jumped down and made a prayer to Poseidon to protect them if the chariot would fall in the sacred grove.
Temples of Poseidon
The Corinthians are considered to be the inventors of the Doric order. However Corinth was completely destroyed and rebuilt and there is not sufficient evidence for the existence of earliest Doric Greek temples in the city. A building constructed in early 7th century BC c. 690-650 BC at Isthmia near Corinth which was later dedicated to Poseidon, is considered a pioneering building featuring Doric architecture. It seems that the first temple with pure Doric elements was built with the aid of Corinthians at Thermon in Aetolia in the middle of 7th century BC century. c.640-630 BC. It was a peripteral narrow wooden structure dedicated to Apollo, It measured 12.13 X38.23 m at the stylobate and the number of pteron columns was 5X15.
In the earlier temples the peripteral colonnade is treated with a freedom unknown to later Doric architects. This is in part an especially western feature (in Italy) because the hexastyle scheme was adopted as in the temple of Poseidon at Taranto and the second temple of Hera at Paestum (traditionally named temple of Poseidon). In the earlier temples where the number of the columns in the porch is odd, so are the columns of the pteron facade. In such temples the side ptera are approximately the width of one or two intercolumniations. In the hexastyle scheme like the temple of Poseidon at Sounion, there are normally two or four columns in the porch and the side ptera are approximately the width of one intercolumniation. In Doric early work the distance between column and column differs on the fronts and on the flanks and this can be observed in the temple of Poseidon at Kalaureia and in Basilica at Paestum. After the 6th century the rule in Doric is an approximate equality of intercolumniations and it can be observed in the temple of Poseidon at Sounion, where there is a slight difference.
Isthmia. The temple dedicated later to the god Poseidon was probably built in early 7th century BC c. 690-650 BC in the city Isthmia near Corinth and it had a wooden peristyle. The building was completely destroyed in 470 BC and it seems that it was one of the pioneering buildings featuring Doric architecture. The ground plan showed a temple that was of epic proportions for its time and of a layout that was almost entirely new, however there was no evidence for the employment of the Doric style as it was suggested
Paestum, on the west coast of Italy near Naples. The Greek name of the city was Poseidonia. The Doric temple was built in the early 6th century BC and it was believed that it was a temple of Poseidon. Traditionally this name is associated with the 5th century BC temple at Paestum, however recent excavations indicate that both temples were dedicated to Hera. The so-called Basilica measured 24,5 X54,3 m at the stylobate and the number of pteron columns was 9x18. The temple is wider than most Greek temples it had two doors. This may indicate a dual dedication of the temple.
Mythology
Birth
In the standard version, Poseidon was born to the Titans Cronus and Rhea, the fifth child out of six, born after Hestia, Demeter, Hera and Hades in that order. Because Poseidon's father was afraid that one of his children would overthrow him like he had done to his own father, Cronus devoured each infant as soon as they were born. Poseidon was the last one to suffer this fate before Rhea decided to deceive Cronus and whisk the sixth child, Zeus, away to safety, after offering Cronus a rock wrapped in a blanket to eat. Once Zeus was grown, he gave his father a powerful emetic that made him gorge up the children he had eaten. The five children emerged from their father's belly in reverse order, making Poseidon both the second youngest child and the second oldest at the same time. Armed with a trident forged for him by the Cyclopes, Poseidon with his siblings and other divine allies defeated the Titans and became rulers in their place. According to Homer and Apollodorus, Zeus, Poseidon and the third brother Hades then divided the world between them by drawing lots; Zeus was allotted the sky, Poseidon the sea, and Hades the Underworld.
In a rarer - and later- version, Poseidon avoided being devoured by his father as his mother Rhea saved him in the same manner she did Zeus, by offering Cronus a foal instead, claiming she had given birth to a horse instead of a god, while she had actually laid the child in a flock. Rhea entrusted her infant to a spring nymph. When Cronus demanded the child, the nymph Sinoessa denied having him, and she was thus called Arne afterwards (which bears resemblance to the Greek word for "deny").
In another tale, Rhea gave Poseidon to the Telchines, ancient inhabitants of the island of Rhodes; Capheira, an Oceanid nymph, became the young god's nurse. As Poseidon grew, he fell in love with Halia, the beautiful sister of the Telchines, and fathered six sons and one daughter, Rhodos, with her. By that time Aphrodite, the goddess of love, had been born and risen from the sea, and attempted to make a stop at Rhodes on her way to Cyprus. Poseidon and Halia's sons denied her hospitality, so Aphrodite cursed them to fall in love and rape Halia. After they had done so, Poseidon made them sink below the sea.
In both Homer's Iliad and Odyssey, Poseidon has a palace beneath the sea at a site called Aegae.
Minor myths
Poseidon broke off a piece of the island of Kos called Nisyros, and threw it on top of Polybotes (Strabo also relates the story of Polybotes buried under Nisyros but adds that some say Polybotes lies under Kos instead).
City patronage
Athena became the patron goddess of the city of Athens after a competition with Poseidon. Yet Poseidon remained a numinous presence on the Acropolis in the form of his surrogate, Erechtheus. At the dissolution festival at the end of the year in the Athenian calendar, the Skira, the priests of Athena and the priest of Poseidon would process under canopies to Eleusis.
They agreed that each would give the Athenians one gift and the Athenians would choose whichever gift they preferred. Poseidon struck the ground with his trident and a spring sprang up; the water was salty and not very useful, but represented his true gift - the access to trade. Athens at its height was a significant sea power, defeating the Persian fleet at the Battle of Salamis.
For her part, Athena offered an olive tree. The Athenians or their king, Cecrops, accepted the olive tree and along with it Athena as their patron, for the olive tree brought wood, oil and food. After the dispute, infuriated at his loss, Poseidon sent a monstrous flood to the Attic Plain, to punish the Athenians for not choosing him. The depression made by Poseidon's trident and filled with salt water was surrounded by the northern hall of the Erechtheum, remaining open to the air.
Burkert noted:"In cult, Poseidon was identified with Erechtheus" and "the myth turns this into a temporal-causal sequence: in his anger at losing, Poseidon led his son Eumolpus against Athens and killed Erectheus."
It was also said that Poseidon in his anger over his defeat sent one of his sons, Halirrhothius, to cut down Athena's tree gift. But as Halirrhothius swung his axe, he missed his aim and it fell on himself, killing him instantly. Poseidon in fury accused Ares of murder, and the matter was eventually settled on the Areopagus ("hill of Ares") in favour of Ares, which was thereafter named after the event. In other versions, Halirrhothius raped Alcippe, Ares's daughter, so Ares slew him. Poseidon was enraged over the murder of his son, and Ares was thus held in hold, which eventually acquitted him.
The contest of Athena and Poseidon was the subject of the reliefs on the western pediment of the Parthenon, the first sight that greeted the arriving visitor.
Theseus
Poseidon fathered the hero Theseus with the Troezenian princess Aethra. Theseus was also said to be the son of Aegeus, the king of Athens, who slept with Aethra on the very same night. Thus Theseus's origins included both the human and the divine element.
Meanwhile, in Crete, Zeus's son Minos asked for Poseidon's help in order to certify his claim on the throne of Crete. Poseidon offered Minos a splendid white bull, with the understanding that he was to sacrifice the bull to Poseidon later. The Cretans were so impressed with the bull and the divine sign itself that Minos was declared king of Crete. But wishing to keep the beautiful animal for himself, Minos instead sacrificed an ordinary bull to the sea-god instead of the agreed upon one.
Poseidon, enraged, caused Minos's wife, Pasiphae, to fall in love with the bull; their coupling produced the Minotaur, a half-bull half-human creature who fed on human flesh. Minos concealed him within the labyrinth built by Daedalus, and fed to him Athenian men and women he forced Aegeus to send him over.
Once Theseus was grown up and recognized by Aegeus as his son, he decided to end the bloody tax Athens had to pay to Crete once and for all, and volunteered to set sail to Crete along with the other Athenian youths who had been chosen to be devoured by the Minotaur.
Once he arrived in Crete, Minos insulted Theseus and insisted he was no son of Poseidon; to demonstrate so, he threw his own ring in to the sea, and commanded Theseus to retrieve it, expecting he would not be able to do so. Theseus immediately dove in after it.
Dolphins then came as guides and escorted him to the halls of Poseidon's palace, where he was warmly welcomed. He received the ring, and in addition a purple wedding cloak and a crown from the Nereid Amphitrite, to prove his words. Theseus then emerged from the sea and gave the ring to Minos. Theseus killed the Minotaur, and in time succeeded his father Aegeus as king of Athens. By an Amazon he had a son, Hippolytus, while his wife Phaedra (Minos' daughter) gave him two sons.
At some point, Poseidon promised three favours to Theseus, and he called upon Poseidon to fulfill one of those when Phaedra falsely accused Hippolytus of forcing himself on her. Theseus, not knowing the truth, asked his father to destroy Hippolytus; Poseidon granted his son's wish, and as Hippolytus was driving by the sea, Poseidon sent a terrifying sea monster to spook the man's horses, which then dragged him to his death.
Walls of Troy
Poseidon and Apollo, having offended Zeus by their rebellion in Hera's scheme, were temporarily stripped of their divine authority and sent to serve King Laomedon of Troy. He had them build huge walls around the city and promised to reward them with his immortal horses, a promise he then refused to fulfill. In vengeance, before the Trojan War, Poseidon sent a sea monster to attack Troy. The monster was later killed by Heracles.
Consort, lovers and children
Poseidon was said to have had many lovers of both sexes. His consort was Amphitrite, an ancient sea-goddess and nymph, daughter of Nereus and Doris. In one account, attributed to the Hellenistic writer Eratosthenes, Poseidon wished to wed Amphitrite, but she fled from him and hid with Atlas. Poseidon sent out many to find her, and it was a dolphin who tracked her down. The dolphin persuaded Amphitrite to accept Poseidon as her husband, and eventually took charge of their wedding. Poseidon then put him among the stars as a reward for his good services. Oppian says that the dolphin betrayed Amphitrite's whereabouts to Poseidon, and he carried off Amphitrite against her will to marry her. Together they had a son named Triton, a merman.
A mortal woman named Cleito once lived on an isolated island; Poseidon fell in love with the human mortal and created a dwelling sanctuary at the top of a hill near the middle of the island and surrounded the dwelling with rings of water and land to protect her. She gave birth to five sets of twin boys; the firstborn, Atlas, became the first ruler of Atlantis.
Poseidon had an affair with Alope, his granddaughter through Cercyon, his son and King of Eleusis, begetting Hippothoon. Cercyon had his daughter buried alive but Poseidon turned her into the local spring.
With Gaia, Poseidon fathered the half-giant Antaeus.
Poseidon was the father of many heroes. He is thought to have fathered the famed Theseus, Bellerophon, Alebion and Bergion. Not all of Poseidon's children were human, though. His other children include the Gigantes Otos and Ephialtes, the Cyclops Polyphemus and, finally, Amycus was the son of Poseidon and the Bithynian nymph Melia. The philosopher Plato was held by his fellow ancient Greeks to have traced his descent to the sea-God Poseidon through his father Ariston and his mythic predecessors the demigod kings Codrus and Melanthus.
Poseidon engaged in homosexual relationships as well. He took the young Nerites, the son of Nereus and Doris (and thus brother to Amphitrite) as a lover. Nerites was also Poseidon's charioteer, and impressed all marine creatures with his speed. But one day the sun god, Helios, turned Nerites into a shellfish. Aelian, who recorded this tale as told by mariners, says it is not clear why Helios did this, but theorizes he might have been offended somehow, or that he and Poseidon were rivals in love, and Helios wanted Nerites to travel among the constellations instead of the sea-monsters. From the love between Poseidon and Nerites was born Anteros, mutual love.
In literature and art
In Greek art, Poseidon lives in a palace on the ocean floor, made of coral and gems. He rides a chariot that is pulled by a hippocampus or by horses that could ride on the sea. He was associated with dolphins and three-pronged fish spears (tridents).
A hymn to Poseidon included among the Homeric Hymns is a brief invocation, a seven-line introduction that addresses the god as both "mover of the earth and barren sea, god of the deep who is also lord of Mount Helicon and wide Aegae", and specifies his twofold nature as an Olympian: "a tamer of horses and a saviour of ships".
In the Iliad, Poseidon favors the Greeks, and on several occasions takes an active part in the battle against the Trojan forces. However, in Book XX, he rescues Aeneas after the Trojan prince is laid low by Achilles.In the Odyssey, Poseidon is notable for his hatred of Odysseus who blinded the sea-god's son, the Cyclops Polyphemus, resulting in Poseidon punishing him with storms, causing the complete loss of his ship and his numerous of his companions. The enmity of Poseidon prevents Odysseus's return home to Ithaca for ten years. Odysseus is even told, notwithstanding his ultimate safe return, that to placate the wrath of Poseidon will require one more voyage on his part. After Odysseus left the island of Calypso, Poseidon, in anger, let loose all four of the Anemoi to cause a storm and raise great waves in order to attempt to drown him.
In the Aeneid, Neptune is still resentful of the wandering Trojans, but is not as vindictive as Juno, and in Book I he rescues the Trojan fleet from the goddess's attempts to wreck it, although his primary motivation for doing this is his annoyance at Juno's having intruded into his domain.
In modern culture
Due to his status as a Greek god, Poseidon has made multiple appearances in modern and popular culture.
Poseidon appeared in the 1963 film Jason and the Argonauts.
Poseidon appears in the Percy Jackson & the Olympians novel series, where he is the father of the titular protagonist Percy Jackson. In the first film adaptation, Percy Jackson & the Olympians: The Lightning Thief, released in 2010, he is portrayed by Kevin McKidd.
Poseidon has made multiple appearances in video games, such as in God of War 3 by Sony. In the game, Poseidon appears as a boss for the player to defeat. In the video game Hades, he is a character who will grant "boons".
