Wolte nun einer weiter sagen; Jn der Philosophen Schrifften / findet man gleichwol hin vnd wieder also viel bericht vnd Lehren / daraus dannoch zu vernehmen / Ja Klar vnd hell zu sehen ist / das diese Kunst in Metallis, als in Silber vnd Golde / stecke; vnd also JN / MJT vnd DVRCH die Metalla / gewißlich müsse gesuchet vnd verrichtet werden: Wie hat es dann darmit eine meynung?

About This Reading Edition

Heinrich Khunrath’s Magnesia Catholica Philosophorum argues that alchemy has one universal subject, that this subject cannot be extracted from the metals, and that nothing in the work can begin without recognizing it. This complete reader begins with the supplied seven-part introduction and orientation, then presents every printed page of the 1599 German treatise opposite its new English translation.

Historical Text and Translation

The German reading text is a fresh diplomatic transcription from 600 dpi images of the Magdeburg copy printed by Johann Bötcher in 1599. It preserves Khunrath’s capitalization, word division, authorial marginal keys, glosses, errata, and three unnumbered closing pages: the errata leaf, owl emblem, and colophon.
