According to Pausanias, Poseidon was one of the caretakers of the oracle at Delphi before Olympian Apollo took it over. Apollo and Poseidon worked closely in many realms: in colonization, for example, Delphic Apollo provided the authorization to go out and settle, while Poseidon watched over the colonists on their way, and provided the lustral water for the foundation-sacrifice. Xenophon's Anabasis describes a group of Spartan soldiers in 400-399 BCE singing to Poseidon a paean - a kind of hymn normally sung for Apollo.
Like Dionysus, who inflamed the maenads, Poseidon also caused certain forms of mental disturbance. A Hippocratic text of ca 400 BCE, On the Sacred Disease says that he was blamed for certain types of epilepsy.
Demeter and Poseidon's names are linked in one Pylos tablet, where they appear as PO-SE-DA-WO-NE and DA, referred to by the epithets Enosichthon, Seischthon and Ennosigaios, all meaning "earth-shaker" and referring to his role in causing earthquakes.
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.
This myth is construed by Robert Graves and others as reflecting a clash between the inhabitants during Mycenaean times and newer immigrants. It is interesting to note that Athens at its height was a significant sea power, at one point defeating the Persian fleet at Salamis Island in a sea battle.
Poseidon was the father of many heroes. He is thought to have fathered the famed Theseus.
A mortal woman named Tyro was married to Cretheus (with whom she had one son, Aeson) but loved Enipeus, a river god. She pursued Enipeus, who refused her advances. One day, Poseidon, filled with lust for Tyro, disguised himself as Enipeus, and from their union were born the heroes Pelias and Neleus, twin boys. Poseidon also had an affair with Alope, his granddaughter through Cercyon, begetting the Attic hero Hippothoon. Cercyon had his daughter buried alive but Poseidon turned her into the spring, Alope, near Eleusis.
After having raped Caeneus, Poseidon fulfilled her request and changed her into a male warrior.
Not all of Poseidon's children were human. In an archaic myth, Poseidon once pursued Demeter. She spurned his advances, turning herself into a mare so that she could hide in a herd of horses; he saw through the deception and became a stallion and captured her. Their child was a horse, Arion, which was capable of human speech. Poseidon also had sexual intercourse with Medusa on the floor of a temple to Athena. Medusa was then changed into a monster by Athena. When she was later beheaded by the hero Perseus, Chrysaor and Pegasus emerged from her neck. There is also Triton, the merman; Polyphemus, the cyclops; and Oto and Ephialtae, the giants.Gill, N.S. Mates and Children of Poseidon. (2007). Retrieved on 2007-02-05..
In Greek art, Poseidon rides a chariot that was pulled by a hippocampus or by horses that could ride on the sea. He was associated with dolphins and three-pronged fish spears (tridents). He lived in a palace on the ocean floor, made of coral and gems.
In the Iliad Poseidon favors the Greeks, and on several occasion 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 due to the latter's having blinded the god's son, the cyclops Polyphemus. The enmity of Poseidon prevents Odysseus's return home to Ithaca for many 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.
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.
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 Helicon and wide Aegae, and specificies his twofold nature as an Olympian: "a tamer of horses and a saviour of ships."
Age of Mythology In the Age Of Mythology Game's Campaign Poseidon is seduced by the power the Titan Kronos promises him in return to setting him free. Poseidon then aids one of his cyclops children Gargarenses in freeing the Titan. They are eventually through mortal means, discovered by Zeus who after the plan is foiled chains Poseidon in Tartarus for his betrayal.
In Masami Kurumada's manga Saint Seiya, the Poseidon war is the second story arc. Poseidon incarnates in the body of the young Julian Solo and plots to get rid of humans to purify the earth. He's defeated by Athena and her Bronze Saints and sealed back to sleep again, although he awakens one more time to help her defeat Hades. He's set to appear in the sequel Lost Canvas, after Athena sends two of her saints to Bluegard, where he was once sealed and is kept, to ask for his help in the war against Hades.
