A cask by losing centre-piece or cant
Was never shattered so, as I saw one
Rent from the chin to where one breaketh wind.
Between his legs were hanging down his entrails;
His heart was visible, and the dismal sack
That maketh excrement of what is eaten.
While I was all absorbed in seeing him,
He looked at me, and opened with his hands
His bosom, saying: "See now how I rend me;
How mutilated, see, is Mahomet;
In front of me doth Ali weeping go,
Cleft in the face from forelock unto chin;
And all the others whom thou here beholdest,
Disseminators of scandal and of schism
While living were, and therefore are cleft thus.
A devil is behind here, who doth cleave us
Thus cruelly, unto the falchion's edge
Putting again each one of all this ream,
When we have gone around the doleful road;
By reason that our wounds are closed again
Ere any one in front of him repass.
- Dante's Inferno, Canto 28
