Tueopuitus saith: Thou hast spoken intelligently and elegantly, and art held free from envy. Saith the Turba: Let your discretion, therefore, explain to us what the instructing Pandolfus has stated, and be not envious. Then he: O all ye seekers after this science, the arcanum of gold and the art of the coin is a dark vestment, and no one knows what the Philosophers have narrated in their books without frequent reading, experiments, and questionings of the Wise. For that which they have concealed is more sublime and obscure than it is possible to make known in words, and albeit some have dealt with it intelligibly and well, certain others have treated it obscurely; thus some are more lucid than others. The Turba answereth: Thou hast truly spoken. And he: I announce to posterity that between boritis and copper there is an affinity, because the boritis of the Wise liquefies the copper, and it changes as a fluxible water. Divide, therefore, the venom into two equal parts, with one of which liquefy the copper, but preserve the other to pound and imbue the same, until it is drawn out into plates; cook again with the former part of the venom, cook two to seven in two; cook to seven in its own water for 42 days;* finally, open the vessel, and ye shall find copper turned into quicksilver; wash the same by cooking until it be deprived of its blackness, and become as copper without a shadow. Lastly, cook it continuously until it be congealed. For when it is congealed it becomes a very great arcanum. Accordingly, the Philosophers have called this stone Boritis;* cook, therefore, that coagulated stone until it becomes a matter like mucra. Then imbue it with the Permanent water which I directed you to reserve, that is to say, with the other portion, and cook it many times until its colours manifest. This, therefore, ls the very great putrefaction which extracts (or contains in itselt) the very great arcanum. Saith the Turba: Return to thine exposition, O Theophilus! And he: It is to be known that the same affinity which exists between the magnet and iron, also exists assuredly between copper and permanent water. If, therefore, ye rule copper and permanent water as I have directed, there will thence result the very great arcanum in the following fashion. Take white Magnesia and quicksilver,* mix with the male, and pound strongly by cooking, not with the hands, until the water become thin. But dividing this water into two parts, in the one part of the water cook it for eleven, otherwise, forty days, until there be a white flower, as the flower of salt in its splendour and coruscation: but strongly close the mouth of the vessel, and cook for forty days, when ye will find it water whiter than milk; deprive it of all blackness by cooking; continue the cooking until its whole nature be disintegrated, until the defilement perish, until it be found clean, and is wholly broken up (or becomes wholly clean). But if ye wish that the whole arcanum, which I have given you, be accomplished, wash the same with water, that is to say, the other part which I counselled you to preserve, until there appear a crocus, and leave in its own vessel. For the Iksir pounds (or contains) itself; imbue also with the residue of the water, until by decoction and by water it be pounded and become like a syrup of pomegranates; imbue it, therefore, and cook, until the weight of the humidity shall fail, and the colour which the Philosophers have magnified shall truly appear.
