 but only by the right adjustment of those which are dissimilar. This discussion on harmony naturally leads to one on music, which is divided, according to the then received writers on the subject, into three kinds—celestial, human, and instrumental. Music, in the Middle Ages, was, for dialectical purposes, treated in accordance with the Pythagorean theory as interpreted by Cicero in his Somnium Scipionis, who represented the eight revolving spheres of heaven—the Earth being fixed—as forming a complete musical octave. Such celestial music forms the subject of the argument in Roswitha's play, the music of Earth being merely touched upon. Why, it is asked, do we not hear this music of the spheres if it exists? To this comes the answer that some think it is because of its continuity, others because of the density of the atmosphere, and others again because the volume of sound cannot penetrate the narrow passage of the human ear. And so with subtle argument, the music of Heaven was often drowned in the din of Earth. Dante, in the Paradiso, lifted the idea once more from Earth to Heaven, and clothed it in a wealth of gorgeous imagery. But it is Shakespeare who, with the magic of a few words, has given the thought immortality.
