Grecorius* saith: O all ye Turba, it is to be observed that the envious have called the venerable’ stone Efflucidinus,t and they have ordered it to be ruled until it coruscates like marble in its splendour.} And go they: Show, therefore, what it is to posterity. Then he: Willingly; you must know that the copper is commingled with vinegar, and ruled until it becomes’ water. Finally, let it be congealed, and it remains a coruscating stone with a brilliancy like marble, which, when ye see thus, I direct you to rule until it becomes red, because when it is cooked till it is disintegrated and becomes earth, it is turned into a red colour. When ye see it thus, repeatedly cook and imbue it until it assume the aforesaid colour, and it shall become hidden gold. Then re-. peat the process, when it will become gold of a Tyrian colour. It behoves you, therefore, O all ye investigators of this Art, when ye have observed that this Stone is coruscating, to pound and turn it into earth, until it acquires some degree of redness; then take the remainder* of the water which the envioust ordered you to divide into two parts, and ye shall imbibe them! several times until the colours which are hidden by no body appear unto you.S Know also that if ye rule it ignorantly, ye shall see nothing of those colours. I knew a certain person who commenced this work, and operated the natures of truth, who, when the redness was somewhat slow in appearing, imagined that he had made a mistake, and so relinquished the work. Observe, therefore, how ye make the conjunction, for the punic dye,* having embraced his spouse, passes swiftly into her body, liquefies, congeals, breaks up, and disintegrates the same. Finally, the redness does not delay in coming, and if ye effect it without the weight, death will take place, whereupon it will be thought to be bad. Hence, I order that the fire should be gentle in liquefaction, but when it is turned to earth make the same intense,t and imbue it until God shall extract the colours for us and they appear.
