The serpent, too, is other than it was at first. Before the fall of man it was the cleverest of all animals created, and in form it resembled man closely. It stood upright, and was of extraordinary size. Afterward, it lost the mental advantages it had possessed as compared with other animals, and it degenerated physically, too; it was deprived of its feet, so that it could not pursue other animals and kill them. The mole and the frog had to be made harmless in similar ways; the former has no eyes, else it were irresistible, and the frog has no teeth, else no animal in the water were sure of its life.
