Polyphemus claims Poseidon will heal his eye

'...Come here, Odysseus, let me give you a guest-gift
and urge Poseidon the earthquake god to speed you home.
I am his son and he claims to be my father, true,
and he himself will heal me if he pleases —
no other blessed god, no man can do the work!’

‘Heal you!’ —
here was my parting shot —‘Would to god I could strip you
of life and breath and ship you down to the House of Death
as surely as no one will ever heal your eye,
not even your earthquake god himself!’

The Odyssey, Book 9, Translated by Robert Fagles.
