Poseidon in The Odyssey

Who is Poseidon?

Poseidon is the Olympian god of the sea who bears a deadly grudge against Odysseus after his son Polyphemus is blinded. From the poem’s opening assembly of the gods Poseidon’s anger is a constant counterforce to Athena’s and Zeus’s plans to restore Odysseus. He actively intervenes at sea: he spots Odysseus’ raft after Calypso releases him and hurls a storm that smashes the craft, driving the hero to cling to wreckage until Ino and Athena assist; later, when the Phaeacians convey Odysseus toward home, Poseidon turns their returning ship to stone in retribution for helping the mortal. Poseidon’s hostility also originates in Polyphemus’ prayer for revenge after Odysseus reveals his name, which explicitly links the god’s wrath to the hero’s boast. Throughout the narrated wanderings and the divine council scenes he remains the principal divine antagonist whose refusal to forgive ensures that the sea itself is an antagonistic, sentient obstacle.

In the book: When we first hear of him, he’s the god of the sea who’s still furious at Odysseus for blinding his cyclops son, Polyphemus. He matters because his grudge keeps the ocean itself stacked against Odysseus, turning every crossing into a fresh bout with storms and setbacks. While the other gods start talking about helping the hero, Poseidon is the one power not ready to forgive.

Personality

Vengeful

After Polyphemus is blinded, Poseidon vows mischief and later hurls a storm that destroys Odysseus’ raft (Book 5).

Powerful

He transforms the Phaeacians’ returning ship into stone as punishment for conveying Odysseus (Book 13).

Unforgiving

At the gods’ assembly he still bears a grudge and refuses to relent despite Zeus and Athena’s plans to help Odysseus (Book 1).

Responsive to prayer

Polyphemus prays to Poseidon for vengeance after Odysseus reveals his name and Poseidon answers that prayer (Book 9).

Imposing presence

Other gods and mortals act cautiously—Athena hides her open interventions for fear of Poseidon’s reaction (Book 6–7).

Character arc

Poseidon’s role is consistent rather than developmental: from his first mention at the gods’ council he is established as the unbeatable divine antagonist whose anger stems from his son Polyphemus’ blinding. That grievance propels concrete deeds—he smites Odysseus’ raft with a violent storm after Calypso sets the hero adrift, ensuring Odysseus’ continued suffering at sea (Book 5). He remains a looming threat that even other gods consider when acting on Odysseus’ behalf; Athena tempers her visible interventions because of his potential reaction (Books 6–7). When the Phaeacians help Odysseus finally reach Ithaca, Poseidon punishes them by turning their returning ship to stone, both avenging Polyphemus and removing a people who aided the hero from their former role as hospitable escorts (Book 13). He does not undergo reconciliation or change—his animosity persists through the narrative, shaping the hero’s path until other divine forces (Zeus, Athena) manage outcomes despite him.

Relationships

• Odysseus Principal divine antagonist whose vengeance repeatedly imperils Odysseus’ voyages.
• Polyphemus Father whose son’s prayer for revenge motivates Poseidon’s wrath against Odysseus.
• Zeus Fellow god who debates Odysseus’ fate with Athena; Poseidon’s anger operates alongside Zeus’s decrees but not always in harmony.
• Athena Countervailing divine force; her interventions are often cautious because of Poseidon’s readiness to retaliate.
• Alcinous Indirectly hostile: Poseidon punishes Alcinous’ people, the Phaeacians, by turning their ship to stone for aiding Odysseus.
• The Phaeacians Victims of his retribution when he petrifies their returning ship after they bring Odysseus home.

Why Poseidon matters

Poseidon embodies the theme of divine power as an independent, sometimes obstructive force that shapes human fate. His sustained grudge demonstrates how a single act—Odysseus’ blinding of Polyphemus—can produce cascading consequences beyond human control, turning the sea itself into moral and physical adversity. He also highlights tensions among the gods: even when Zeus and Athena favor Odysseus, Poseidon’s refusal to forgive complicates the restoration of order. In this way Poseidon reinforces themes of hubris, retribution, and the precariousness of mortal journeys under volatile divine wills.
