...

Insieme si rispuosero a tai norme,
che 'l serpente la coda in forca fesse,
e 'l feruto ristrinse insieme l'orme.

Le gambe con le cosce seco stesse
s'appiccar sì, che 'n poco la giuntura
non facea segno alcun che si paresse.

Togliea la coda fessa la figura
che si perdeva là, e la sua pelle
si facea molle, e quella di là dura.

Io vidi intrar le braccia per l'ascelle,
e i due piè de la fiera, ch'eran corti,
tanto allungar quanto accorciavan quelle.

Poscia li piè di rietro, insieme attorti,
diventaron lo membro che l'uom cela,
e 'l misero del suo n'avea due porti.

Mentre che 'l fummo l'uno e l'altro vela
di color novo, e genera 'l pel suso
per l'una parte e da l'altra il dipela,

l'un si levò e l'altro cadde giuso,
non torcendo però le lucerne empie,
sotto le quai ciascun cambiava muso.

Quel ch'era dritto, il trasse ver' le tempie,
e di troppa matera ch'in là venne
uscir li orecchi de le gote scempie;

ciò che non corse in dietro e si ritenne
di quel soverchio, fé naso a la faccia
e le labbra ingrossò quanto convenne.

Quel che giacëa, il muso innanzi caccia,
e li orecchi ritira per la testa
come face le corna la lumaccia;

e la lingua, ch'avëa unita e presta
prima a parlar, si fende, e la forcuta
ne l'altro si richiude; e 'l fummo resta.

Together they responded in such wise,
That to a fork the serpent cleft his tail,
And eke the wounded drew his feet together.

The legs together with the thighs themselves
Adhered so, that in little time the juncture
No sign whatever made that was apparent.

He with the cloven tail assumed the figure
The other one was losing, and his skin
Became elastic, and the other's hard.

I saw the arms draw inward at the armpits,
And both feet of the reptile, that were short,
Lengthen as much as those contracted were.

Thereafter the hind feet, together twisted,
Became the member that a man conceals,
And of his own the wretch had two created.

While both of them the exhalation veils
With a new colour, and engenders hair
On one of them and depilates the other,

The one uprose and down the other fell,
Though turning not away their impious lamps,
Underneath which each one his muzzle changed.

He who was standing drew it tow'rds the temples,
And from excess of matter, which came thither,
Issued the ears from out the hollow cheeks;

What did not backward run and was retained
Of that excess made to the face a nose,
And the lips thickened far as was befitting.

He who lay prostrate thrusts his muzzle forward,
And backward draws the ears into his head,
In the same manner as the snail its horns

And so the tongue, which was entire and apt
For speech before, is cleft, and the bi-forked
In the other closes up, and the smoke ceases.
