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. Purgatorio: Canto XXVI While on the brink thus one before the other We went upon our way, oft the good Master Said: “Take thou heed! suffice it that I warn thee.”
