Prato saith: It behoves you all, O Masters, when those bodies are being dissolved, to take care lest they be burnt up, as also to wash them with sea water, until all their salt be turned into sweetness, clarifies, tinges, becomes tincture of copper, and then goes off in flight! Because it was necessary that one should become tingeing, and that the other should be tinged, for the spirit being separated from the body and hidden in the other spirit, both become volatile. Therefore the Wise have said that the gate of flight must not be opened for that which would flee, (or that which does not flee),* by whose flight death is occasioned, for by the conversion of the sulphureous thing into a spirit like unto itself, either becomes volatile, since they are made aeriform spirits prone to ascend in the air. But the Philosophers seeing that which was not volatile made volatile with the volatiles, iterated these to a body like to the non-volatiles, and put them into that from which they could not escape.* They iterated them to a body like unto the bodies from which they were extracted, and the same were then digested. But as for the statement of the Philosopher that the tingeing agent and that which is to be tinged are made one tincture, it refers to a spirit concealed in another humid spirit. Know also that one of the humid spirits is cold, but the other is hot, and although the cold humid is not adapted to the warm humid, nevertheless they are made one. Therefore, we prefer these two bodies, because by them we rule the whole work, namely, bodies by not-bodies, until incorporeals become bodies, steadfast in the fire, because they are conjoined with volatiles, which is not possible in any body, these excepted. For spirits in every wise avoid bodies, but fugitives are restrained by incorporeals. Incorporeals, therefore, similarly flee from bodies; those, consequently, which do not flee are better and more precious than all bodies. These things, therefore, being done, take those which are not volatile and join them; wash the body with the incorporeal until the incorporeal receives a non-volatile body; convert the earth into water, water into fire, fire into air, and conceal the fire in the depths of the water, but the earth in the belly of the air, mingling the hot with the humid, and the cold with the dry. Know, also, that Nature overcomes Nature, Nature rejoices in Nature, Nature contains Nature.
