Betus saith: O all ye Philosophers, ye have not dealt sparingly concerning composition and contact, but composition, contact, and congelation are one thing! Take, therefore, a part from the one composition and a part out of ferment of gold,* and on these impose pure water of sulphur. This, then, is the potent (or revealed)arcanum which tinges every body. PyTHAGORAS answereth: O Belus, why hast thou called it a potent arcanum, yet hast not shown its work? And he: In our books, O Master, we have found the same which thou hast received from the ancients! And PyTHAGORAS: Therefore have I assembled you together, that you might remove any obscurities which are in any books. And he: Willingly, O Master! It is to be noted that pure water which is from sulphur is not composed of sulphur alone, but is composed of several things, for the one sulphur is made out of several sulphurs.t How, therefore, O Master, shall I compose these things that they may become one? And he: Mix, O Belus, that which strives with the fire with that which does not strive, for things which are conjoined in a fire suitable to the same contend, because the warm venoms of the physician are cooked ina gentle, incomburent fire!* Surely ye perceive what the Philosophers have stated concerning decoction, that a little sulphur burns many strong things, and the humour which remains is called humid pitch, balsam of gum, and other like things. Therefore our Philosophers are made like to the physicians, notwithstanding that the tests of the physicians are more intense than those of the Philosophers. The Turba answereth: I wish, O Belus, that you would also shew the disposition of this potent arcanum! And he: I proclaim to future generations that this arcanum proceeds from two compositions, that is to say, sulphur and magnesia. But after it is reduced and conjoined into one, the Philosophers have called it water, spume of Boletus (z.e., a species of fungus), and the thickness of gold. When, however, it has been reduced into quicksilver, they call it sulphur of water; sulphur also, when it contains sulphur, they term a fiery venom, because it is a potent (or open) arcanum which ascends from those things ye know.
