And I again, “Master, where are Phlegethon and Lethe found, for of the one thou art silent, and of the other thou sayest that it is formed by this rain?” “In all thy questions surely thou pleasest me,” he answered, “but the boiling of the red water ought truly to solve one that thou askest. Lethe thou shalt see, but outside of this ditch, there where souls go to lave themselves when sin repented of is taken away.” Then he said, “Now it is time to depart from the wood; take heed that thou come behind me; the margins afford way, for they are not burning, and above them all the vapor is extinguished.” CANTO XV. Third round of the Seventh Circle: of those who have done violence to Nature.—Brunetto Latini.—Prophecies of misfortune to Dante. Now one of the hard margins bears us on, and the fume of the brook overshadows so that it saves the water and the banks from the fire. As the Flemings, between Wissant and Bruges, fearing the flood that is blown in upon them, make the dyke whereby the sea is routed; and as the Paduans along the Brenta, in order to defend their towns and castles, ere Chiarentana[1] feel the heat,—in such like were these made, though neither so high nor so thick had the master, whoever he was, made them.

Thus gazed at by that company, I was recognized by one who took me by the hem, and cried out, “What a marvel!” And when he stretched out his arm to me, I fixed my eyes on his baked aspect so that his scorched visage prevented not my mind from recognizing him; and bending down my own to his face, I answered, “Are you here, Sir Brunetto?”[1] And he, “O my son, let it not displease thee if Brunetto Latini turn a little back with thee, and let the train go on.” I said to him, “With all my power I pray this of you, and if you will that I seat myself with you I will do so, if it pleaseth this one, for I go with him.” “O son,” said he, “whoever of this herd stops for an instant lies then a hundred years without fanning himself when the fire smites him; therefore go onward, I will come at thy skirts, and then I will rejoin my band which goeth weeping its eternal sufferings.”
