As the lizard under the great scourge of the dog days, changing from hedge to hedge, seems a flash, if it crosses the way, so seemed, coming toward the belly of the two others, a little fiery serpent, livid, and black as a grain of pepper. And that part whereby our nourishment is first taken it transfixed in one of them, then fell down stretched out before him. The transfixed one gazed at it, but said nothing; nay rather, with feet fixed, he yawned even as if sleep or fever had assailed him. He looked at the serpent, and that at him; one through his wound, the other through his mouth, smoked violently, and their smoke met. Let Lucan henceforth be silent, where he tells of the wretched Sabellus, and of Nasidius, and wait to hear that which now is uttered. Let Ovid be silent concerning Cadmus and Arethusa, for if, poetizing, he converts him into a serpent and her into a fountain, I envy him not; for two natures front to front never did he transmute, so that both the forms were prompt to exchange their matter. To one another they responded by such rules, that the serpent made his tail into a fork, and the wounded one drew together his feet. The legs and the very thighs with them so stuck together, that in short while the juncture made no sign that was apparent. The cleft tail took on the shape that was lost there, and its skin became soft, and that of the other hard. I saw the arms draw in through the armpits, and the two feet of the beast which were short lengthen out in proportion as those shortened. Then the hinder feet, twisted together, became the member that man conceals, and the wretched one from his had two[1] stretched forth. [1] Hinder feet. While the smoke is veiling both with a new color, and generates hair on the one, and from the other strips it, one rose up, and the other fell down, not however turning aside their pitiless lights,[1] beneath which each was changing his visage. He who was erect drew his in toward the temples, and, from the excess of material that came in there, issued the ears on the smooth cheeks; that which did not run backwards but was retained, of its superfluity made a nose for the face, and thickened the lips so far as was needful. He who was lying down drives his muzzle forward, and draws in his ears through his skull, as the snail doth his horns. And his tongue, which erst was united and fit for speech, cleaves itself, and the forked one of the other closes up; and the smoke stops. The soul that had become a brute fled hissing along the valley, and behind him the other speaking spits. Then he turned upon him his new shoulders, and said to the other,[2] “I will that Buoso[3] run, as I have done, groveling along this path.” [1] Glaring steadily at each other. [2] The third of the three spirits, the only one unchanged. [3] Buoso is he who has become a snake.
