Preface.

...want to add the judgment of the incomparable Chemist and Polymath Polyhistor original: "Polyhistoris"; a scholar of vast and diverse learning across many fields. Olaus Borrichius original: "Olai Borrichii"; a prominent 17th-century Danish physician and alchemist who wrote early histories of chemistry., which he delivers regarding this author of ours in his Overview of More Illustrious Chemists original: "Conspectu Chymicorum illustriorum" section 51, page 33:

Heinrich Khunrath comments in a proper work on the fires of the Magi, and on various kinds of fires; but it is a wonder that he does not touch upon that true fire of the Philosophers by even a single word, and nonetheless he is quite long-winded in his assessment of others. original Latin: "Henricus Khunrad de Ignibus Magorum, deque variis ignium generibus justo opere commentatur, sed mirum, quod verum istum Philosophorum ignem ne verbo quidem attingat, & nihilominus in aliis censendis prolixus est." Borrichius is offering a common academic critique of the time: that Khunrath talks around the "secret" of alchemy without revealing it directly.

We heartily wish that this work may be blessed, and that it may create much benefit for all who research the impartial truth; and with this, we recommend the well-disposed reader to the Divine goodness for all that is good.
