Poseidon myths and symbols center on his role as the Greek god of the sea, earthquakes, and horses, with the trident as his most iconic attribute. In ancient Greek religion and mythology, Poseidon was one of the twelve Olympians, a brother of Zeus and Hades, and a deity whose power could both nurture and destroy.
Origins and Family
Poseidon was the son of the Titans Cronus and Rhea. According to Hesiod’s Theogony, Cronus swallowed his children at birth to prevent them from overthrowing him, but Zeus later forced Cronus to disgorge them, and Poseidon emerged as a fully grown god. After the Olympians defeated the Titans, the three brothers divided the cosmos: Zeus took the sky, Hades the underworld, and Poseidon the sea. The earth and Mount Olympus remained shared territory.
Poseidon’s consorts and offspring are numerous and vary by source. His wife was the sea goddess Amphitrite, a Nereid, with whom he fathered Triton, a merman who blew a conch shell to calm or stir the waves. He also had many mortal and immortal children, including the hero Theseus (though his paternity is disputed), the Cyclops Polyphemus, and the winged horse Pegasus, born from Medusa after her death. Regional traditions often claimed local kings or heroes as his descendants, which reinforced his importance across the Greek world.
The Trident and Other Symbols
The trident is Poseidon’s most recognizable symbol. It was a three-pronged spear, often forged by the Cyclopes, and it served multiple purposes: striking the earth to cause earthquakes, splitting rocks to create springs, and stirring the sea to create storms or calm waters. In art, Poseidon is almost always depicted holding the trident, sometimes with a fish or dolphin nearby.
Other symbols associated with Poseidon include:
- The horse – He was called Poseidon Hippios and was credited with creating the first horse, either by striking the ground with his trident or by mating with the Gorgon Medusa. He was also the patron of horse racing and cavalry.
- The dolphin – Dolphins were sacred to him and often appeared in mosaics and vase paintings as companions.
- The bull – In some myths, especially those involving Crete, Poseidon sent or embodied bulls, such as the Cretan Bull that fathered the Minotaur.
- The fish – Fish were natural symbols of his domain, and he was sometimes shown riding a chariot pulled by hippocampi (horse-fish hybrids).
Myths of Wrath and Generosity
Poseidon’s myths often depict him as vengeful and competitive, but also as a bestower of gifts. One famous myth is his contest with Athena for the patronage of Athens. Poseidon struck the Acropolis with his trident and produced a saltwater spring, while Athena offered an olive tree. The Athenians chose Athena’s gift, and Poseidon, angered, flooded the plain of Attica in retaliation (though some versions say he later relented).
Another well-known story involves Odysseus. In Homer’s Odyssey, Poseidon punishes Odysseus for blinding his son Polyphemus the Cyclops by sending storms and delaying his journey home for ten years. This myth illustrates his power over the sea and his willingness to hold grudges against mortals who offended him or his kin.
Poseidon also played a role in the Trojan War. He favored the Greeks and helped them build the walls of Troy, but when King Laomedon refused to pay him, Poseidon sent a sea monster to terrorize the city. Later, during the war itself, he opposed the Trojans, though he was not a central figure in the conflict.
Worship and Cults
Poseidon was widely worshipped across Greece, particularly in coastal cities and islands. His sanctuaries were often located near the sea, such as the Temple of Poseidon at Cape Sounion in Attica, which still stands today. The Isthmian Games, held near Corinth, were dedicated to him and included athletic and equestrian competitions. Sailors and fishermen offered sacrifices to him before voyages, hoping for safe passage.
In some regions, Poseidon was also worshipped as a god of fresh water and springs, especially in inland areas like Thessaly, where he was associated with horses and agriculture. His cult titles varied by location, reflecting his many functions: Poseidon Asphaleios (the secure) protected harbors, while Poseidon Gaiaochos (the earth-holder) was linked to earthquakes.
Poseidon in Art and Literature
In ancient Greek art, Poseidon was typically portrayed as a mature, bearded man with a powerful build, similar to Zeus but distinguished by his trident and often a more turbulent expression. The famous bronze statue of Poseidon from Cape Artemision (c. 460 BCE) shows him poised to throw his trident, capturing his dynamic energy. Vase paintings frequently depict him in scenes with Amphitrite, the birth of Athena (where he was present), or the gigantomachy, the battle against the Giants.
In literature, Poseidon appears in Homer’s Iliad and Odyssey, Hesiod’s Theogony, and the Homeric Hymn to Poseidon. His character is consistent: powerful, moody, and deeply concerned with honor and respect. Later Roman writers identified him with Neptune, who adopted many of his myths and symbols, though Neptune was originally a minor god of fresh water.
Common Misconceptions
A frequent misconception is that Poseidon was solely a sea god. In early Greek religion, he was also a god of earthquakes and horses, and his connection to the sea may have developed later. Another error is confusing him with Triton, his son, who is a minor sea god. Additionally, while Poseidon is often called the “god of the sea,” he was not the only deity with power over water; Oceanus, Tethys, and the Nereids also had roles, but Poseidon was the supreme Olympian ruler of the saltwater realm.
Some modern retellings portray Poseidon as a villain or a mere antagonist to heroes, but in ancient sources he was a complex figure who could be generous and protective. For example, he helped the Greeks in the Trojan War, and he was the patron of many cities, including Corinth.
Poseidon’s Legacy
Poseidon’s influence extends beyond ancient Greece. The Romans adopted him as Neptune, and his iconography appears in Renaissance art and modern popular culture, from films like Clash of the Titans to the Percy Jackson series, where he is a central character. His trident remains a universal symbol of maritime power, used in emblems of navies and shipping companies.
In astronomy, the planet Neptune was named after his Roman counterpart, and its moons include Triton. In geology, the term “Poseidonian” is occasionally used to describe earthquake-related phenomena, though it is not a standard scientific term. His myths continue to be studied for insights into ancient Greek values, particularly the importance of hospitality, honor, and the unpredictability of nature.
Frequently Asked Questions

Why is Poseidon called the god of earthquakes?
Poseidon was called the “Earth-Shaker” because he could cause earthquakes by striking the ground with his trident. This reflects the ancient Greeks’ belief that seismic activity was caused by the god’s anger or movement, and it links his maritime and terrestrial powers.

Poseidon had many children, including Triton (with Amphitrite), Theseus (with Aethra, in some accounts), Polyphemus the Cyclops (with the nymph Thoosa), and Pegasus and Chrysaor (from Medusa). He was also the father of numerous local heroes and kings, such as Bellerophon and Orion, depending on the myth.

Zeus is more prominent in myths and often acts as the arbiter among gods, whereas Poseidon is more localized to maritime concerns and is more easily angered.
Did Poseidon have a temple?
