Synopsis
The Processus Universalis related to Sendivogius (1566–1636) was subject to much experimentation between 1600 and 1750. One of the contributing alchemists was Andreas Orthelius (1583-?). In his tractatus Michaelis Sendivogi Poloni Lumen Chymicum Novum XII. Tractatibus (1624) he reconstructed not only a corrupted text fragment, but also contextualized its individual steps with regard to philosophical background and experimental realization. For his contemporaries this piece of work provided interpretational and experimental assistance. For modern researchers these explanations allow insight into contemporary process developments. In addition to his broad knowledge of literature, an evaluation of Saxonian archive records also demonstrates his practical skill concerning the Processus Universalis.
