"So, Cyclops, no weak coward it was whose crew
you bent to devour there in your vaulted cave –
you with your brute force! Your filthy crimes
came down on your own head, you shameless cannibal,
daring to eat your guests in your own house –
so Zeus and the other gods have paid you back."
That made the rage of the monster boil over.
– Homer
The Odyssey, Book 9, lines 531-537. Odysseus just cannot keep his pride and ego under control. After blinding and outsmarting Polyphemus, he is now safely offshore in his boat. But he shouts back and taunts Polyphemus, telling him that for eating his guests, Polyphemus has been dealt divine justice by Zeus. Using a metaphor in a verb, Homer likens the anger of the Cyclops to boiling liquid spilling over.
