ZENON saith: I perceive that you, O crowd of the Wise, have conjoined two bodies, which your Master by no means ordered you todo! The Turba answereth: Inform us according to your own opinion, O Zenon, in this matter, and beware of envy! Then he: Know that the colours which shall appear to you out of it are these. Know, O Sons of the Doctrine, that it behoves you to allow the composition to putrefy for forty days, and then to sublimate five times in a vessel. Next join to a fire of dung, and cook, when these colours shall appear to you: On the first day black citrine, on the second black red, on the third like unto a dry crocus,* finally, the purple colour will appear to you; the ferment and the coin of the vulgar shall be imposed; then is the Ixir composed out of the humid and the dry, and then it tinges with an invariable tincture. Know also that it is called a body wherein there is gold. But when ye are composing the Ixir, beware lest you extract the same hastily, for it lingers.t Extract, therefore, the same as an Ixir. For this venom is, as it were, birth and life, because it is a soul extracted out of many things, and imposed upon coins:i its tincture, therefore, is life to those things with which it is joined, from which it removes evil, but it is death to the bodies from which it is extracted. Accordingly, the Masters have said that between them there exists the same desire as between male and female, and if any one, being introduced to this Art, should know these natures, he would sustain the tediousness of cooking until he gained his purpose according to the will of God.
