(Ποσειδῶν, Poseidōn)^[1]https://en.wikipedia.org/wiki/List_of_Greek_mythological_figures

God of the sea, rivers, floods, droughts, and earthquakes. He is a son of Cronus and Rhea, and the brother of Zeus and Hades. He rules one of the three realms of the universe, as king of the sea and the waters. In art he is depicted as a mature man of sturdy build, often with a luxuriant beard, and holding a trident. His sacred animals include the horse and the dolphin. His wedding with Amphitrite is often presented as a triumphal procession. In some stories he rapes Medusa, leading to her transformation into a hideous Gorgon and also to the birth of their two children, Pegasus and Chrysaor. His Roman counterpart is Neptune.

Poseidon and the heroes

Poseidon,[3] as god of the sea, was an important Olympian power; he was the chief patron of Corinth, many cities of Magna Graecia, and also of Plato‘s legendary Atlantis. He controls the oceans and the seas,[4] and he also created horses. As such, he was intimately connected with the pre-historic office of king – whose chief emblem of power and primary sacrificial animal was the horse. Thus, on the Mycenean Linear B tablets found at Pylos, the name Poseidon[5] occurs frequently in connection with the wanax (“king”), whose power and wealth were increasingly maritime rather than equestrian in nature. Surprisingly, Poseidon’s name is found with greater frequency than that of Zeus, and is commonly linked (often in a secondary role) with Demeter. Poseidon[6] is brothers with Zeus along with Hades and his father was Cronus, the leader of the Titans.

When the office of wanax disappeared during the Greek Dark Ages, the link between Poseidon and the kingship was largely, although not entirely, forgotten. In classical Athens, Poseidon was remembered as both the opponent and doublet of Erechtheus, the first king of Athens. Erechtheus was given a hero-cult at his tomb under the title Poseidon Erechtheus.

In another possible echo of this archaic association, the chief ritual of Atlantis, according to Plato‘s Critias, was a nocturnal horse-sacrifice offered to Poseidon[7] by the kings of the imagined island power.

In keeping with the mythic equation between horsemanship and seamanship, the equestrian heroes Castor and Pollux were invoked by sailors against shipwreck. Ancient Greeks interpreted the phenomenon now called St. Elmo’s Fire as the visible presence of the two brothers.
