Turba Philosophorum
The Twenty-Fourth Dictum
Bocascus* saith: Thou hast spoken well, O Belus, and therefore I follow thy steps!
He answereth: As it may please you, but do not become envious, for that is not the part of the Wise. And Bocascus: Thou speakest the truth, and thus, therefore, I direct the Sons of the Doctrine. Take lead, and, as the Philosophers have ordained, imbue, liquefy, and afterwards congeal, until a stone is produced; then rule the stone with gluten of gold and syrup of pomegranates until it be broken up. But you have already divided the water into two parts, with one of which you have liquefied the lead, and it has become as water; cook, therefore, the same until it be dried and have become earth; then pound with the water reserved until it acquire a red colour, as you have been frequently ordered.*
The Turba answereth: Thou hast done nothing but pile up ambiguous words, Return, therefore, to the subject. And he: Ye who wish to coagulate quicksilver,t must mix it with its equal.
Afterwards cook it diligently until both become permanent water, and, again, cook this water until it be coagulated. But let this be desiccated with its own equal vapour, because ye have found the whole quicksilver to be coagulated by itself.* If ye understand, and place in your vessel what is necessary, cook it until it be coagulated, and then poundt until it becomes a crocus like to the colour of gold.
