Q. Why do hard dens, hollow and high places, send back the likeness and sound of the voice? A. Because that in such places also by reflection do return back the image of a sound, for the voice doth beat the air, and the air the place, which the more it is beaten the more it doth bear, and therefore doth cause the more vehement sound of the voice; moist places, and as it were, soft, yielding to the stroke, and dissolving it, give no sound again; for according to the quantity of the stroke, the quality and quantity of the voice is given, which is called an echo. Some do idly fable that she is a goddess; some say that Pan was in love with her, which without doubt is false. He was some wise man, who did first desire to search out the cause of the voice, and as they who love, and cannot enjoy that love, are grieved, so in like manner was he very sorry until he found out the solution of that cause; as Endymion also, who first found out the course of the moon, watching all night, and observing her course, and searching her motion, did sleep in the daytime, and that she came to him when he was asleep, because she did give the philosopher the solution of the course herself. They say also that he was a shepherd, because that in the desert and high places, he did mark the course of the moon. And they gave him also the pipe because that the high places are blown with wind, or else because he sought out the consonancy of figures. Prometheus also, being a wise man, sought the course of the star, which is called the eagle in the firmament, his nature and place; and when he was, as it were, wasted with the desire of learning, then at last he rested, when Hercules did resolve unto him all doubts with his wisdom. Q. Why do not swine cry when they are carried with their snouts upwards? A. Because that of all other beasts they bend more to the earth. They delight in filth, and that they seek, and therefore in the sudden change of their face, they be as it were strangers, and being amazed with so much light do keep that silence; some say the windpipe doth close together by reason of the straitness of it. Q. Why do swine delight in dirt? A. As physicians do say, they are naturally delighted with it, because they have a great liver, in which desire it, as Aristotle saith, the wideness of their snout is the case, for he that hath smelling which doth dissolve itself, and as it were strive with stench.
