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
“Its grossness is clearly perceived in an actual experiment: for first it is black and looks like lead or antimony; then it is of a whitish colour, and is called Jupiter (or tin, or magnesia), and this also before it has attained true whiteness, but when it has passed the white stage, it is called Mars and Venus; after that it becomes perfect and red.”
