And it is not without reason added, that the mass of matter whereof man was formed, should be mixed up with particles taken from different animals, and wrought in with the clay, because it is certain, that of all things in the universe, man is the most compounded and recompounded body; so that the ancients, not improperly, styled him a Microcosm, or little world within himself. For although the chemists have absurdly, and too literally, wrested and perverted the elegance of the term microcosm, whilst they pretend to find all kind of mineral and vegetable matters, or something corresponding to them, in man, yet it remains firm and unshaken, that the human body is, of all substances, the most mixed and organical; whence it has surprising powers and faculties; for the powers of simple bodies are but few, though certain and quick; as being little broken, or weakened, and not counterbalanced by mixture; but excellence and quantity of energy reside in mixture and composition. Man, however, in his first origin, seems to be a defenceless, naked creature, slow in assisting himself, and standing in need of numerous things. Prometheus, therefore, hastened to the invention of fire, which supplies and administers to nearly all human uses and necessities, insomuch that, if the soul may be called the form of forms, if the hand may be called the instrument of instruments, fire may, as properly, be called the assistant of assistants, or the helper of helps; for hence proceed numberless operations, hence all the mechanic arts, and hence infinite assistances are afforded to the sciences themselves. The manner wherein Prometheus stole this fire is properly described from the nature of the thing; he being said to have done it by applying a rod of birch to the chariot of the Sun; for birch is used in striking and beating, which clearly denotes the generation of fire to be from the violent percussions and collisions of bodies; whereby the matters struck are subtilized, rarefied, put into motion, and so prepared to receive the heat of the celestial bodies; whence they, in a clandestine and secret manner, collect and snatch fire, as it were by stealth, from the chariot of the Sun.
