On alchemy original Greek: "περὶ χημείας" When I wished to grant several selected books of the ancients on alchemy from our library to the printers to be published, so that a greater benefit might flow from them to the students of Philosophy, I thought I should provide a brief preface. I do not doubt that many men, who are indeed good but unskilled in the nature of things, think this whole kind of art should be entirely rejected and covered in silence.

Therefore, decide for yourself whether the knowledge of their nature is more useful or more pleasant—
