Passing by many other such like things, said I, I will produce only Plato; who says, that there is but one world, but that if this were not alone, so that there were others besides it, they would be in all five and no more. For indeed, though there is but this one only world, as Aristotle is also of opinion, yet this world is in some sort composed and assembled of five, of which one indeed is of earth, another of water, the third of fire, the fourth of air, and the fifth, being heaven, some call light and others the sky; and some also name this same the fifth essence, which alone of all, bodies is naturally carried about in a circle, and not of necessity or otherwise by accident. Wherefore Plato, knowing that, of the figures which are in Nature, there are five most excellent and perfect,—to wit, the pyramid, the cube, the octahedron, the icosahedron, and the dodecahedron,—has fitly accommodated each of them to each of these worlds or bodies.

There are some also who apply the faculties of the senses, being equal in number, to these five first bodies, seeing the touch to be firm and earthly, and the taste to perceive the qualities of savors by moisture. Now the air being struck upon is a voice and sound to the ear; and as for the other two,—the scent, which the smell has obtained for its object, being an exhalation and engendered by heat, is fiery; and the sight, which shines by reason of its affinity to the sky and light, has from them a temperature and complexion equally mingled of both. Now neither has any animal any other sense, nor the world any other nature simple and unmixed; but there has been made, as appears, a certain wonderful distribution and congruity of five to five.
