Stoops to the lowlands.  Under each shot forth
Two mighty wings, enormous as became
A bird so vast.  Sails never such I saw
Outstretch’d on the wide sea.  No plumes had they,
But were in texture like a bat, and these
He flapp’d i’ th’ air, that from him issued still
Three winds, wherewith Cocytus to its depth
Was frozen.  At six eyes he wept:  the tears
Adown three chins distill’d with bloody foam. 
At every mouth his teeth a sinner champ’d
Bruis’d as with pond’rous engine, so that three
Were in this guise tormented.  But far more
Than from that gnawing, was the foremost pang’d
By the fierce rending, whence ofttimes the back
Was stript of all its skin.  “That upper spirit,
Who hath worse punishment,” so spake my guide,
“Is Judas, he that hath his head within
And plies the feet without.  Of th’ other two,
Whose heads are under, from the murky jaw
Who hangs, is Brutus:  lo! how he doth writhe
And speaks not!  Th’ other Cassius, that appears
So large of limb.  But night now re-ascends,
And it is time for parting.  All is seen.”

I clipp’d him round the neck, for so he bade;
And noting time and place, he, when the wings
Enough were op’d, caught fast the shaggy sides,
And down from pile to pile descending stepp’d
Between the thick fell and the jagged ice.

Soon as he reach’d the point, whereat the thigh
Upon the swelling of the haunches turns,
My leader there with pain and struggling hard
Turn’d round his head, where his feet stood before,
And grappled at the fell, as one who mounts,
That into hell methought we turn’d again.

“Expect that by such stairs as these,” thus spake
The teacher, panting like a man forespent,
“We must depart from evil so extreme.” 
Then at a rocky opening issued forth,
And plac’d me on a brink to sit, next join’d
With wary step my side.  I rais’d mine eyes,
Believing that I Lucifer should see
Where he was lately left, but saw him now
With legs held upward.  Let the grosser sort,
Who see not what the point was I had pass’d,
Bethink them if sore toil oppress’d me then.

“Arise,” my master cried, “upon thy feet. 
The way is long, and much uncouth the road;
And now within one hour and half of noon
The sun returns.”  It was no palace-hall
Lofty and luminous wherein we stood,
But natural dungeon where ill footing was
And scant supply of light.  “Ere from th’ abyss
I sep’rate,” thus when risen I began,
“My guide! vouchsafe few words to set me free
From error’s thralldom.  Where is now the ice? 
How standeth he in posture thus revers’d? 
And how from eve to morn in space so brief
Hath the sun made his transit?” He in few
Thus answering spake:  “Thou deemest thou art still
On th’ other side the centre, where I grasp’d
Th’ abhorred worm, that boreth through the world.
