"I never had doubts myself, no, I knew down deep
that you would return at last, with all your shipmates lost.
I could not bring myself to fight my Father’s brother,
Poseidon, quaking with anger at you, still enraged
because you blinded the Cyclops, his dear son."

– Homer

The Odyssey, Book 13, lines 386-390. Athena explains to Odysseus why she did not help him sooner during his travels after Troy. She was fearful of inciting her father’s brother Poseidon, when he flew into a rage after Odysseus blinded his son Polyphemus.
