Acsubofen* saith: Master, thou hast spoken without envy, even as became thee, and for the same may God reward thee! PyTHacoras saith: May God also deliver thee, Acsubofen, from envy! Then he: Ye must know, O Assembly of the Wise, that sulphurs are contained in sulphurs, and humidity in humidity.t The Turba answereth: The envious, O Acsubofen, have uttered something like unto this! Tell us, therefore, what is this humidity? And he: Humidity is a venom, and when venom} penetrates a body, it tinges it with an invariable colour, and in no wise permits the soul to be separated from the body, because it is equal thereto. Concerning this, the envious have said: When one flies and the other pursues, then one seizes upon the other, and afterwards they no longer flee, because Nature has laid hold of its equal, after the manner of an enemy, and they destroy one another. For this reason, out of the sulphureous mixed sulphur is produced a most precious colour, which varies not, nor flees from the fire, when the soul enters into the interior of the body and holds the body together and tinges it. I will repeat my words in Tyrian dye.* Take the Animal which is called Kenckel, since all its water is a Tyrian colour, and rule the same with a gentle fire, as is customary, until it shall become earth, in which there will be a little colour. But if you wish to obtain the Tyrian tincture, take the humidity which that thing has ejected, and place it therewith gradually in a vessel, adding that tincture whereof the colour was disagreeable to you. Then cook with that same marine water* until itshall becomedry.t Afterwards moisten with that humour, dry gradually, and cease not to imbue it, to cook, and to dry, until it be imbued with all its humour. Then leave it for several days in its own vessel, until the most precious Tyrian colour shall come out from it to the surface. Observe how I describe the regimen to you! Prepare it with the urine of boys, with gigt water of the sea, and with permanent clean water, so that it may be tinged, and decoct with a gentle fire, until the blackness altogether shall depart from it, and it be easily pounded. Decoct, therefore, in its own humour until it clothe itself with a red colour. But if ye wish to bring it to the Tyrian colour, imbue the same with continual* water, and mix, as ye know to be sufficient, according to the rule of sight; mix the same with permanent water sufficiently, and decoct until rust absorb the water. Then wash with the water of the sea which thou hast prepared, which is water of desiccated calx;+ cook until it imbibe its own moisture; and do this day by day. I tell you thata colour will thence appear to you the like of which the Tyrians have never made. And if ye wish that it should be a still more exalted colour, place the gum in the permanent water, with which ye shall dye it alternately, and afterwards desiccate in the sun. Then restore to the aforesaid water and the black Tyrian colour is intensified. But know that ye do not tinge the purple colour except by cold. Take, therefore, water which is of the nature of cold, and steep wool* therein until it extract the force of the tincture from the water. Know also that the Philosophers have called the force which proceeds from that water the Flower. Seek, therefore, your intent in the said water; therein place what is in the vessel for days and nights, until it be clothed with a most precious Tyrian colour.
