PARMENIDES saith:—Ye must know that envious men have dealt voluminously with several waters, brodiums, stones, and metals, seeking to deceive all you who aspire after knowledge. Leave, therefore, all these, and make the white red, out of this our copper, taking copper and lead, letting these stand for the grease, or blackness, and tin for the liquefaction. Know ye, further, that unless ye rule the Nature of Truth, and harmonize well together its complexions and compositions, the consanguineous with the consanguineous, and the first with the first, ye act improperly and effect nothing, because natures will meet their natures, follow them, and rejoice. For in them they putrefy and are generated, because Nature is ruled by Nature, which The Turba Philosophorum. 33 destroys it, turns it into dust, reduces to nothing, and finally herself renews it, repeats, and frequently produces the same. Therefore look in books, that ye may know the Nature of Truth, what putrefies it and what renews, what savour it possesses, what neighbours it naturally has, and how they love each other, how also after love enmity and corruption intervene, and how these natures should be united one to another and made at peace, until they become gentle in the fire in similar fashion. Having, therefore, noticed the facts in this Art, set your hands to the work. If indeed, ye know not the Natures of Truth, do not approach the work, since there will follow nothing but harm, disaster,and sadness. Consider, therefore, the teaching of the Wise, how they have declared the whole work in this saying:—Nature rejoices in Nature, and Nature contains Nature. In these words there is shewn forth unto you the whole work. Leave, therefore, manifold and superfluous things, and take D tee quicksilver,* coagulate in the body of Magnesia,f in Kuhul, or in Sulphur which does not burn; make the same nature white, and place it upon our Copper, when it becomes white. And if ye cook still more, it becomes red, when if ye proceed to coction, it becomes gold. I tell you that it turns the sea itself into red and the colour of gold. Know ye also that gold is not turned into redness save by Permanent Water, because Nature rejoices in Nature.} Reduce, therefore, the same by means of cooking into a humour, until the hidden nature appear. If, therefore, it be manifested externally, seven times imbue the same with water, cooking, imbuing, and washing, until it become red. O those celestial natures, multiplying the natures of truth by the will of God! Othat potent Nature, which overcame and conquered natures, and caused its natures to rejoice and be glad!* This, therefore, is that special and spiritual nature to which the God thereof can give what fire cannot. Consequently, we glorify and magnify that jspecies], than which nothing is more precious in the true tincture, or the like in the smallest degree to be found. This is that truth which those investigating wisdom love. For when it is liquefied with bodies, the highest operation is effected. If ye knew the truth, what great thanks ye would give me! Learn, therefore, that while you are tingeing the cinders, you must destroy those that are mixed. For it overcomes those which are mixed, and changes them to its own colour. And as it visibly overcame the surface, even so it mastered the interior. And if one be volatile but the other endure the fire, either joined to the other endures the fire. Know also, that if the vapours have whitened the surfaces, they will certainly whiten the interiors. Know further, all ye seekers after Wisdom, that one matter overcomes four, and our Sulphur* alone consumes all things. The Turba answereth: Thou hast spoken excellently well, O Parmenides, but thou hast not demonstrated the disposition of the smoke to posterity, nor how the same is whitened!
