Poseidon hates Odysseus because Odysseus blinded the god’s son, the Cyclops Polyphemus, and then arrogantly taunted Poseidon by revealing his true name. This act of violence against his offspring, compounded by Odysseus’s prideful boast, earned the sea god’s undying wrath and directly caused the ten-year delay of Odysseus’s journey home to Ithaca.
The Blinding of Polyphemus
The root of Poseidon’s hatred lies in Book 9 of Homer’s Odyssey. After the Trojan War, Odysseus and his crew landed on the island of the Cyclopes, a race of one-eyed giants. They entered the cave of Polyphemus, who trapped them inside and began eating the men. To escape, Odysseus devised a plan: he offered the Cyclops strong wine, and when Polyphemus asked his name, Odysseus said he was “Nobody” (Outis in Greek). When Polyphemus fell into a drunken sleep, Odysseus and his men drove a sharpened olive stake into his single eye, blinding him.
Polyphemus’s cries brought other Cyclopes, but when they asked who was hurting him, he shouted, “Nobody is killing me!” So they left, and Odysseus and his men escaped by clinging to the undersides of the Cyclops’s sheep. As they sailed away, Odysseus could not resist shouting his real name: “Odysseus, son of Laertes, of Ithaca!” This boast was fatal—Polyphemus then prayed to his father Poseidon to curse Odysseus, and the god heard the prayer.
Poseidon’s Role as Father and Avenger
In Greek mythology, Poseidon was a powerful and vengeful god, and his children were often fierce or monstrous. Polyphemus was one of his sons, and the blinding was not just an injury to a monster—it was an attack on the god’s own bloodline. In the ancient world, harming a child of a god was a grave offense, and the god was expected to retaliate. Poseidon’s hatred was therefore not arbitrary; it was a father’s response to a direct assault on his son.
Homer makes this explicit in the Odyssey when Polyphemus prays: “Grant that Odysseus, sacker of cities, son of Laertes, who lives in Ithaca, may never reach his home.” Poseidon hears the prayer and answers it, though he cannot kill Odysseus outright because the other gods, especially Athena, protect him. Instead, he makes the journey home as miserable and long as possible.
How Poseidon’s Wrath Manifests
Poseidon’s hatred is not a passive grudge; it actively shapes the plot of the Odyssey. After leaving Troy, Odysseus’s fleet is blown off course by storms that are often attributed to Poseidon. The most dramatic manifestation comes when Odysseus leaves the island of Ogygia, where the nymph Calypso had kept him for seven years. Poseidon sees him sailing on a raft and sends a massive storm that destroys the raft, forcing Odysseus to swim for his life. He is only saved by the intervention of the sea goddess Ino, who gives him a magical veil to keep him afloat.
Even after Odysseus finally reaches the island of the Phaeacians, Poseidon punishes them for helping him. The god turns their returning ship to stone, and then, at Zeus’s suggestion, he buries their city under a mountain. This shows that Poseidon’s anger extends beyond Odysseus to anyone who aids him.
Why Odysseus’s Boast Mattered
Odysseus’s decision to reveal his name was a crucial turning point. In Homeric culture, kleos (glory) was earned through great deeds, and Odysseus wanted the Cyclops to know who had defeated him. But this pride (hubris) was a fatal flaw. Had he remained “Nobody,” Polyphemus would not have known whom to curse, and Poseidon might not have acted. The boast turned a personal victory into a divine vendetta.
This moment also highlights a common theme in Greek mythology: the danger of excessive pride. The gods punished mortals who overstepped their bounds, and Odysseus’s taunt was a clear overstep. He was not just boasting to a monster; he was claiming glory that belonged to the gods, and Poseidon’s reaction was a lesson in humility.
Was Poseidon’s Hatred Justified?
From a mortal perspective, Odysseus was acting in self-defense—he had to blind Polyphemus to escape being eaten. But from a divine perspective, the blinding was a sacrilege, and the boast was an insult. Greek myths often present gods as having their own moral codes, and Poseidon’s vengeance was considered legitimate within that framework. Even Athena, who favored Odysseus, could not stop Poseidon entirely; she could only delay his wrath until Odysseus reached home.
It is also worth noting that Poseidon’s hatred is not eternal. In Book 13 of the Odyssey, after Odysseus returns to Ithaca, Poseidon complains to Zeus about the Phaeacians’ help. Zeus proposes that Poseidon turn their ship to stone, which he does, and then the matter is dropped. The god’s anger seems to subside once he has made his point and Odysseus is home.
Other Gods’ Perspectives and Interventions
Poseidon’s hatred is counterbalanced by Athena’s protection. Athena, the goddess of wisdom, admired Odysseus for his cunning and repeatedly interceded on his behalf. She persuaded Zeus to send Hermes to Calypso to order Odysseus’s release, and she guided him through the Phaeacians. However, she could not override Poseidon directly; the gods generally respected each other’s domains and grudges. Zeus, the king of the gods, remained neutral, though he allowed Odysseus to suffer as long as Poseidon’s anger was not satisfied.
This divine conflict also reflects the ancient Greek worldview: the gods were not all-powerful in a modern sense; they had personalities, favorites, and rivalries. Odysseus’s journey was as much a test of his endurance as it was a divine chess game.
Frequently Asked Questions
Did Poseidon ever forgive Odysseus?
In Homer’s Odyssey, Poseidon does not explicitly forgive Odysseus. He stops actively pursuing him after Odysseus returns to Ithaca, but the text does not show a reconciliation. The god’s anger is satisfied when Odysseus is punished enough—he loses all his men, his ship, and spends ten years wandering—so Poseidon’s wrath fades into the background.
Why didn’t Poseidon just kill Odysseus?
Poseidon could not kill Odysseus because the other gods, especially Athena, protected him. In Greek mythology, the gods could not simply override each other’s will without consequence. Zeus had decreed that Odysseus would return home, and Poseidon had to abide by that, though he could make the journey as painful as possible.
Was Polyphemus really Poseidon’s son?
Yes, in Homer’s Odyssey, Polyphemus is explicitly called the son of Poseidon. The Cyclops prays to his father, and Poseidon hears him. Other sources, such as Hesiod’s Theogony, describe the Cyclopes as sons of Uranus and Gaia, but Homer’s version is the one that matters for the story of Odysseus.
Did Odysseus ever apologize to Poseidon?
No, Odysseus never apologizes to Poseidon. In fact, after blinding Polyphemus, he boasts about it, which only increases the god’s anger. Odysseus’s journey is a punishment, not a quest for forgiveness.
What would have happened if Odysseus had not revealed his name?
If Odysseus had remained “Nobody,” Polyphemus would not have known who to curse, and Poseidon likely would not have targeted him specifically. Odysseus might have returned home much sooner, but he would have lost the glory of having his deed known. The entire epic of the Odyssey depends on that moment of pride.
Are there other myths where Poseidon punishes mortals?
Yes, Poseidon frequently punished mortals who offended him. For example, he cursed King Minos’s wife Pasiphae to fall in love with a bull, and he sent a sea monster to terrorize the kingdom of Troy because King Laomedon refused to pay him for building the city walls. These stories show that Poseidon’s wrath was a recurring theme in Greek mythology.
