Answer :

Because Odysseus made the Cyclops Polyphemus, who was the son of Poseidon, blind, he than delayed the hero's onward voyage towards home from the Trojan War. Not only did he delay his voyage home, but also caused him to face enormous perils. At one point in the story, Poseidon lashed his Trident at the sea and had caused a storm that was so fierce, it wrecked Odysseus's ship.
