Poseidon: Why Is He Known as the God of the Sea, Earthquakes, and Horses?
When speaking about Greek mythology, few figures carry the same sense of raw power and commanding presence as Poseidon, the mighty god of the sea, earthquakes, and horses.

But why did the ancient Greeks see Poseidon as such a central force in their world? What made him more than just a sea deity, and how did his worship shape the lives and beliefs of those who honored him?

Who Was Poseidon in Greek Mythology?
Poseidon was one of the Olympian gods, brother to Zeus, the ruler of the skies, and Hades, lord of the underworld. Born from the union of Cronus and Rhea, Poseidon was part of the generation that fought in the Titanomachy, the great battle where the Olympian gods overthrew the Titans to establish their reign. After the victory, the three brothers divided the cosmos: Zeus took the heavens, Hades received the underworld, and Poseidon claimed the sea. This division of realms gave Poseidon his vast kingdom beneath the waves, where he reigned over oceans, storms, and all marine creatures.
Why Was Poseidon Associated with the Sea?
"The ancient Greeks were a maritime people. The Aegean, Mediterranean, and Ionian Seas surrounded their land, making seafaring, fishing, and trade essential parts of life. To them, the sea represented both opportunity and danger. Calm waters could bring wealth, while storms could sink fleets in an instant. Poseidon embodied this dual nature. He was not merely a peaceful god of waters; he was unpredictable, moody, and often destructive. Sailors prayed to him before voyages, offered sacrifices to calm his temper, and built temples near harbors to gain his favor. His trident, a three-pronged spear, symbolized his authority over the waves, with a single strike said to be able to stir up violent storms or calm the seas at will."
How Did Poseidon Become the God of Earthquakes?
While Poseidon is most famously linked with the sea, his role as the “Earth-Shaker” was equally feared. Ancient myths describe how he could strike the ground with his trident, causing massive earthquakes that shattered cities and swallowed land. Greece, being a region prone to seismic activity, naturally connected these devastating natural events to the wrath of a god. To them, earthquakes were not random but acts of divine will, and Poseidon’s volatile temper explained the sudden destruction. His epithet Enosichthon, meaning “earth-shaker,” became one of his defining titles, reminding mortals that his power extended beyond the seas and into the very ground beneath their feet.
What Is Poseidon’s Connection to Horses?
Among Poseidon’s most intriguing attributes is his role as the god of horses. Legends tell that he created the first horse, either as a gift or as part of his rivalry with Athena when competing for the patronage of Athens. In this myth, Poseidon struck the ground with his trident, and instead of water, a magnificent horse emerged, symbolizing strength, speed, and nobility. The horse became sacred to him, and he was often invoked in horse-related rituals, chariot races, and equestrian contests. His association with horses highlighted not just physical power but also the bond between humanity and nature, where control and wildness constantly clashed.
What Symbols Are Connected with Poseidon?
Poseidon’s symbols reinforced his divine authority and recognizable identity. The most iconic was the trident, which served as both a weapon and a symbol of power. Dolphins and fish represented his dominion over marine life, while horses reflected his role as their divine protector. Bulls were also linked to him, often sacrificed in his honor during religious festivals. In art, Poseidon was typically depicted as a strong, bearded man with a stern expression, holding his trident, sometimes surrounded by sea creatures or riding a chariot drawn by hippocamps, mythical horse-fish hybrids. These images emphasized both his majestic and fearsome qualities.
How Did Poseidon Interact with Mortals and Heroes?
Poseidon’s personality was as unpredictable as the sea he ruled. He could be a protector, but he could also unleash fury upon those who angered him. One of his most famous conflicts was with Odysseus, whom he punished after the Trojan War for blinding his son, the Cyclops Polyphemus. This grudge caused Odysseus’s long, perilous journey home, filled with storms and obstacles. Yet Poseidon could also favor mortals, especially those who honored him properly. Heroes like Theseus and Jason often sought his blessing, reflecting the belief that no great venture by sea could succeed without his support.
Why Did Poseidon Compete with Athena for Athens?
One of the best-known myths involving Poseidon concerns his rivalry with Athena over the city of Athens. Both gods wanted the city as their patronage, so they offered gifts to its people. Poseidon struck the ground with his trident, producing either a saltwater spring or a horse. Athena, however, gifted the olive tree, which symbolized peace, prosperity, and longevity. The Athenians chose Athena’s gift, and the city took her name. While Poseidon lost this contest, the story illustrates his creativity, his role in shaping civilization, and his connection to natural forces.
How Was Poseidon Worshiped in Ancient Greece?
Worship of Poseidon extended across Greece, particularly in coastal regions and islands. He was honored at sanctuaries such as the Isthmus of Corinth, where the Isthmian Games were held in his honor, featuring athletic and equestrian contests. Sailors would dedicate offerings before setting out to sea, while fishermen and traders sought his blessings for safe voyages and bountiful catches. Ritual sacrifices often included bulls or horses, reflecting his dual roles. His cult was not limited to the sea; in inland regions, he was still venerated for his power over earthquakes and horses, showing his wide-reaching influence across Greek society.
What Myths Highlight Poseidon’s Temper?
Poseidon’s myths often emphasize his volatile nature. He joined Hera and Athena in a conspiracy to overthrow Zeus, only to face humiliation when the plan failed. His rivalry with other gods and mortals frequently ended in violent punishments. For example, when King Minos of Crete refused to sacrifice a bull Poseidon had gifted him, the god cursed Minos’s wife, Pasiphaë, causing her unnatural desire for the bull, which ultimately led to the birth of the Minotaur. These stories illustrate that Poseidon was not a distant deity but an active and unpredictable force whose influence could change the fate of entire kingdoms.
