Henry Wadsworth Longfellow
Purgatorio: Canto 25
Purgatorio: Canto XXV

Now was it the ascent no hindrance brooked,
  Because the sun had his meridian circle
  To Taurus left, and night to Scorpio;

Wherefore as doth a man who tarries not,
  But goes his way, whate'er to him appear,
  If of necessity the sting transfix him,

In this wise did we enter through the gap,
  Taking the stairway, one before the other,
  Which by its narrowness divides the climbers.

And as the little stork that lifts its wing
  With a desire to fly, and does not venture
  To leave the nest, and lets it downward droop,

Even such was I, with the desire of asking
  Kindled and quenched, unto the motion coming
  He makes who doth address himself to speak.

Not for our pace, though rapid it might be,
  My father sweet forbore, but said: "Let fly
  The bow of speech thou to the barb hast drawn."
With confidence I opened then my mouth,
  And I began: "How can one meagre grow
  There where the need of nutriment applies not?"

"If thou wouldst call to mind how Meleager
  Was wasted by the wasting of a brand,
  This would not," said he, "be to thee so sour;

And wouldst thou think how at each tremulous motion
  Trembles within a mirror your own image;
  That which seems hard would mellow seem to thee.

But that thou mayst content thee in thy wish
  Lo Statius here; and him I call and pray
  He now will be the healer of thy wounds."

"If I unfold to him the eternal vengeance,"
  Responded Statius, "where thou present art,
  Be my excuse that I can naught deny thee."

Then he began: "Son, if these words of mine
  Thy mind doth contemplate and doth receive,
  They'll be thy light unto the How thou sayest.

The perfect blood, which never is drunk up
  Into the thirsty veins, and which remaineth
  Like food that from the table thou removest,
Takes in the heart for all the human members
  Virtue informative, as being that
  Which to be changed to them goes through the veins

Again digest, descends it where 'tis better
  Silent to be than say; and then drops thence
  Upon another's blood in natural vase.

There one together with the other mingles,
  One to be passive meant, the other active
  By reason of the perfect place it springs from;

And being conjoined, begins to operate,
  Coagulating first, then vivifying
  What for its matter it had made consistent.

The active virtue, being made a soul
  As of a plant, (in so far different,
  This on the way is, that arrived already,)

Then works so much, that now it moves and feels
  Like a sea-fungus, and then undertakes
  To organize the powers whose seed it is.

Now, Son, dilates and now distends itself
  The virtue from the generator's heart,
  Where nature is intent on all the members.
But how from animal it man becomes
  Thou dost not see as yet; this is a point
  Which made a wiser man than thou once err

So far, that in his doctrine separate
  He made the soul from possible intellect,
  For he no organ saw by this assumed.

Open thy breast unto the truth that's coming,
  And know that, just as soon as in the foetus
  The articulation of the brain is perfect,

The primal Motor turns to it well pleased
  At so great art of nature, and inspires
  A spirit new with virtue all replete,

Which what it finds there active doth attract
  Into its substance, and becomes one soul,
  Which lives, and feels, and on itself revolves.

And that thou less may wonder at my word,
  Behold the sun's heat, which becometh wine,
  Joined to the juice that from the vine distils.

Whenever Lachesis has no more thread,
  It separates from the flesh, and virtually
  Bears with itself the human and divine;

The other faculties are voiceless all;
  The memory, the intelligence, and the will
  In action far more vigorous than before.

Without a pause it falleth of itself
  In marvellous way on one shore or the other;
  There of its roads it first is cognizant.

Soon as the place there circumscribeth it,
  The virtue informative rays round about,
  As, and as much as, in the living members.

And even as the air, when full of rain,
  By alien rays that are therein reflected,
  With divers colours shows itself adorned,

So there the neighbouring air doth shape itself
  Into that form which doth impress upon it
  Virtually the soul that has stood still.

And then in manner of the little flame,
  Which followeth the fire where'er it shifts,
  After the spirit followeth its new form.

Since afterwards it takes from this its semblance,
  It is called shade; and thence it organizes
  Thereafter every sense, even to the sight.

Thence is it that we speak, and thence we laugh;
  Thence is it that we form the tears and sighs,
  That on the mountain thou mayhap hast heard.

According as impress us our desires
  And other affections, so the shade is shaped,
  And this is cause of what thou wonderest at."

And now unto the last of all the circles
  Had we arrived, and to the right hand turned,
  And were attentive to another care.

There the embankment shoots forth flames of fire,
  And upward doth the cornice breathe a blast
  That drives them back, and from itself sequesters.

Hence we must needs go on the open side,
  And one by one; and I did fear the fire
  On this side, and on that the falling down.

My Leader said: "Along this place one ought
  To keep upon the eyes a tightened rein,
  Seeing that one so easily might err."

"Summae Deus clementiae," in the bosom
  Of the great burning chanted then I heard,
  Which made me no less eager to turn round;

And spirits saw I walking through the flame;
  Wherefore I looked, to my own steps and theirs
  Apportioning my sight from time to time.

After the close which to that hymn is made,
  Aloud they shouted, "Virum non cognosco;"
  Then recommenced the hymn with voices low.

This also ended, cried they: "To the wood
  Diana ran, and drove forth Helice
  Therefrom, who had of Venus felt the poison."

Then to their song returned they; then the wives
  They shouted, and the husbands who were chaste.
  As virtue and the marriage vow imposes.

And I believe that them this mode suffices,
  For all the time the fire is burning them;
  With such care is it needful, and such food,

That the last wound of all should be closed up.
