Preface.

O happy science, which is sought in the one who knows: Not undeservedly it is to be searched for above all the sciences of this world, because whoever has it, has an incomparable treasure: he is born into this age in a healthy constellation.

Rich in infinite wealth, above the kings and princes of this world, who would not love such things? He who preserves himself, using it, healthy and long-lived above all the medicines of doctors.

These are goods just before GOD and men, not acquired through usury, or through the fraud and deception of many: but it is a special gift of GOD, as the Psalm says: You shall eat the labors of your hands; blessed are you, etc.

Hermes) Whoever has once perfected this art, if he were to live for a thousand thousand years, and nourish four thousand people every single day, he would not be in need.
