There are several versions of the manuscript and depending on the library, the number, order and certain details of the figures differ. The Zurich manuscript is the oldest. We also recovered the additional figures present in the Leiden manuscripts ( Vossiani Chemici F. 29. Glasgow Ferguson 6 figures are available PSI
To the extent that the text accompanying the images is an anthology of biblical and alchemical texts which are not necessarily linked to the images, we will not reproduce it here, especially since the French translation is not a priori free from right.




































































Quote of the Day
“It is necessary therefore, to dissolve and liquefy these bodies by our water, and to make them a permanent or fixed water, a pure, golden water leaving in the bottom the gross, earthy, superfluous and dry matter. And in this subliming, making thin and pure, the fire ought to be gentle; but if in this subliming with soft fire, the bodies be not purified, and the gross and earthy parts thereof (note this well) be not separated from the impurities of the dead, you shall not be able to perfect the work. For thou needest nothing but the thin and subtile part of the dissolved bodies, which our water will give thee, if thou proceedest with a slow or gentle fire, by separating the things heterogene from the things homogene.”
