BoneE.tuus saith: I will speak a little concerning Magnesia. The Turba answereth: Speak. And he: O all ye Sons of the Doctrine, when mixing Magnesia, place it in its vessel, the mouth of which close carefully, and cook with a gentle fire until it liquefy, and all become water therein! For the heat of the water acting thereupon, it becomes water by the will of God. When ye see that the said water is about to become black, ye know that the body is already liquefied. Place again in its vessel, and cook for forty days, until it drink up the moisture of the vinegar and honey.* But certain persons uncover it, say, once in each week, or once in every ten nights; in either case, the ultimate perfection of pure water appears at the end of forty days, for then it completely absorbs the humour of the decoction. Therefore, wash the same, and deprive of its blackness, until, the blackness being removed, the stone becomes dry to the touch. Hence the envious have said: Wash the Magnesia with soft water, and cook diligently, until it become earth, and the humour perish. Then it is called copper. Subsequently, pour very sharp vinegar upon it, and leave it to be soaked therein. But this is our copper, which the Philosophers have ordained should be washed with permanent water, wherefore they have said: Let the venom* be divided into two parts, with one of which burn up the body, and with the other putrefy. And know, all ye seekers after this Science, that the whole work and regimen does not take place except by water, wherefore, they say that the thing which ye seek is one, and, unless that which improves it be present in the said thing, what ye look for shall in no wise take place. Therefore, it behoves you to add those things which are needful, that ye may thereby obtain that which you purpose. The Turba answereth: Thou has spoken excellently, O Bonellus! If it please thee, therefore, finish that which thou art saying; otherwise repeat it a second time. But he: Shall I indeed repeat these and like things? O all ye investigators of this Art, take our copper; place with the first part of the water in the vessel; cook for forty days; purify from all uncleanliness; cook further until its days be accomplished, and it become a stone having no moisture. Then cook until nothing remains except feeces.* This done, cleanse seven times, wash with water, and when the water is used up leave it to putrefy in its vessel, so long as may seem desirable to your purpose. But the envious called this composition when it is turned into blackness that which is sufficiently black, and have said: Rule the same with vinegar and nitre. But that which remained when it had been whitened they called sufficiently white, and ordained that it should be ruled with permanent water. Again, when 122 The Turba Philosopherum. they called the same sufficiently red, they ordained that it should be ruled with water and fire until it became red. The Turba answereth: Show forth unto posterity what they intended by these things. And he: They called. it [xiv satis, by reason of the variation of its colours. In the work, however, there is neither variety, multiplicity, nor opposition of substances; it is necessary only to make the black copper white and then red. However, the truth-speaking Philosophers had no other intention than that of liquefying, pounding, and cooking Ixir until the stone should become like unto marble in its splendour. Accordingly, the envious again said: Cook the same with vapour until the stone becomes coruscating by reason of its brilliancy. But when ye see it thus, it is, indeed, the most great Arcanum. Notwithstanding, ye must then pound and wash it seven times with permanent water; finally, again pound and congeal in its own water, until ye extract its own concealed nature. Wherefore, saith Maria, sulphurs are contained in sulphurs, but humour in like humour, and out of sulphur mixed with sulphur, there comes forth a great work. But I ordain that you rule the same with dew * and the sun, until your purpose appear to you. For I signify unto you that there are two kinds of whitening and of making red, of which one consists in rustt and the other in contrition and decoction. But ye do not need any contrition of hands. Beware, however, of making a separation from the waters lest the poisons get at you, and the body perish with the other things which are in the vessel.t
