The Inferno, Canto 7, lines 8-9: "Curs'd wolf! thy fury inward on thyself Prey, and consume thee!"

Extract from Dante's The Divine Comedy, "Hell", Canto 7, lines 1-15. Translation by The Rev. H. F. Cary, M.A.

"Ah me! O Satan! Satan!" loud exclaim'd
Plutus, in accent hoarse of wild alarm:
And the kind sage, whom no event surpris'd,
To comfort me thus spake: "Let not thy fear
Harm thee, for power in him, be sure, is none
To hinder down this rock thy safe descent."
Then to that sworn lip turning, "Peace!" he cried,
"Curs'd wolf! thy fury inward on thyself
Prey, and consume thee! Through the dark profound
Not without cause he passes. So 't is will'd
On high, there where the great Archangel pour'd
Heav'n's vengeance on the first adulterer proud."

As sails full spread and bellying with the wind
Drop suddenly collaps'd, if the mast split;
So to the ground down dropp'd the cruel fiend.
