One, and two figures blended in one form
Appear’d, where both were lost.  Of the four lengths
Two arms were made:  the belly and the chest
The thighs and legs into such members chang’d,
As never eye hath seen.  Of former shape
All trace was vanish’d.  Two yet neither seem’d
That image miscreate, and so pass’d on
With tardy steps.  As underneath the scourge
Of the fierce dog-star, that lays bare the fields,
Shifting from brake to brake, the lizard seems
A flash of lightning, if he thwart the road,
So toward th’ entrails of the other two
Approaching seem’d, an adder all on fire,
As the dark pepper-grain, livid and swart. 
In that part, whence our life is nourish’d first,
One he transpierc’d; then down before him fell
Stretch’d out.  The pierced spirit look’d on him
But spake not; yea stood motionless and yawn’d,
As if by sleep or fev’rous fit assail’d. 
He ey’d the serpent, and the serpent him. 
One from the wound, the other from the mouth
Breath’d a thick smoke, whose vap’ry columns join’d. 
     Lucan in mute attention now may hear,
Nor thy disastrous fate, Sabellus! tell,
Nor shine, Nasidius!  Ovid now be mute. 
What if in warbling fiction he record
Cadmus and Arethusa, to a snake
Him chang’d, and her into a fountain clear,
I envy not; for never face to face
Two natures thus transmuted did he sing,
Wherein both shapes were ready to assume
The other’s substance.  They in mutual guise
So answer’d, that the serpent split his train
Divided to a fork, and the pierc’d spirit
Drew close his steps together, legs and thighs
Compacted, that no sign of juncture soon
Was visible:  the tail disparted took
The figure which the spirit lost, its skin
Soft’ning, his indurated to a rind. 
The shoulders next I mark’d, that ent’ring join’d
The monster’s arm-pits, whose two shorter feet
So lengthen’d, as the other’s dwindling shrunk. 
The feet behind then twisting up became
That part that man conceals, which in the wretch
Was cleft in twain.  While both the shadowy smoke
With a new colour veils, and generates
Th’ excrescent pile on one, peeling it off
From th’ other body, lo! upon his feet
One upright rose, and prone the other fell. 
Not yet their glaring and malignant lamps
Were shifted, though each feature chang’d beneath. 
Of him who stood erect, the mounting face
Retreated towards the temples, and what there
Superfluous matter came, shot out in ears
From the smooth cheeks, the rest, not backward dragg’d,
Of its excess did shape the nose; and swell’d
Into due size protuberant the lips. 
He, on the earth who lay, meanwhile extends
His sharpen’d visage, and draws down the ears
Into the head, as doth the slug his horns. 
His tongue continuous before and apt
For utt’rance, severs; and the other’s fork
Closing unites.  That done the smoke was laid.
