The heart inside him growled low with rage,
as a bitch mounting over her weak, defenseless puppies
growls, facing a stranger, bristling for a showdown –
so he growled from his depths, hackles rising at their outrage.

– Homer

The Odyssey, Book 20, lines 15-18. An angry and vengeful Odysseus plots the downfall of the suitors and the servant girls who are sleeping with them. An epic simile, foreshadowing their punishment, compares his raging heart to a growling bitch confronting a stranger to protect her puppies.
