The autographs of the writings of Paracelsus were completely lost. Fortunately, Johannes Huser (ca. 1545-1600/1601) had early collected a large number of autographs and copies of these works, so that he was able to publish a monumental complete edition of Paracelsus. The edition of Paracelsus's medical and natural-philosophical works was printed in ten volumes in Basel from 1589 to 1591. Huser had also prepared further volumes with the surgical writings. However, since there were competing editions in Basel with surgical writings by Paracelsus, these remaining writings could only be published in Strasbourg in 1605, when Huser had already died. Huser had taken great care to change the original wording as little as possible, apart from modernising the language. We can therefore assume that with this edition we have a very reliable text at our disposal.
