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
