Not in another fashion Tydeus gnawed
The temples of Menalippus in disdain,
Than that one did the skull and the other things.

“O thou, who showest by such bestial sign
Thy hatred against him whom thou art eating,
Tell me the wherefore,” said I, “with this compact,

That if thou rightfully of him complain,
In knowing who ye are, and his transgression,
I in the world above repay thee for it,

If that wherewith I speak be not dried up.”

Inferno: Canto XXXIII

His mouth uplifted from his grim repast,
That sinner, wiping it upon the hair
Of the same head that he behind had wasted.

Then he began: “Thou wilt that I renew
The desperate grief, which wrings my heart already
To think of only, ere I speak of it;

But if my words be seed that may bear fruit
Of infamy to the traitor whom I gnaw,
Speaking and weeping shalt thou see together.

I know not who thou art, nor by what mode
Thou hast come down here; but a Florentine
Thou seemest to me truly, when I hear thee.

Thou hast to know I was Count Ugolino,
And this one was Ruggieri the Archbishop;
Now I will tell thee why I am such a neighbour.
