Poseidon (Neptune)

Poseidon embodies divine wrath and vengeance, serving as the primary supernatural antagonist in Odysseus (Ulysses)' long journey home. As god of the sea and father to the blinded Cyclops Polyphemus, he has legitimate cause for anger, yet his relentless pursuit of Odysseus (Ulysses) across the wine-dark sea extends beyond reasonable retribution into something more akin to obsessive hatred. His power is immense: he can raise storms, shipwreck fleets, and make the ocean itself a hostile environment that threatens Odysseus (Ulysses) at nearly every turn.

What makes Poseidon's antagonism particularly significant is that it cannot be directly confronted or overcome through cunning, as Odysseus (Ulysses) might manage against mortal foes. His divine authority is near absolute in his domain, the sea, and even gods sympathetic to Odysseus (Ulysses)—particularly Athene—must work within constraints imposed by Poseidon's prerogatives. This dynamic illustrates one of the epic's central tensions: the limits of human agency and intelligence when opposed by arbitrary divine power. Poseidon's eventual withdrawal from active antagonism (as he visits distant lands) allows for Odysseus (Ulysses)' final journey home, suggesting that even divine wrath eventually yields to the passage of time and the inevitability of fate.
