Fire, Vulcanus, Archeus, and Alchemy: A Hybrid Close-Distant Reading of Paracelsus's Thought on Active Agents

The Swiss physician and philosopher Theophrastus von Hohenheim, called Paracelsus (1493-1541) is known for his strong advocacy of medical alchemy. That his natural philosophy was tied to medical alchemy is perhaps uncontroversial, but just how it was so is less straightforward. This article provides an insight into the connection between the two by means of Paracelsus's concept of active agents, with an emphasis on fire, its master Vulcanus, and the associated term Archeus. I will show how these evolved in the thought of Paracelsus by taking an evolutionary view of his works. The complexity of his views comes to light as a result of employing the method of hybrid reading, which integrates the traditional close reading technique with the much more novel one of distant reading. The latter is part of the emerging field of digital and computational humanities, and involves the analysis of corpora by means of digital tools, including computer programming (Python). In the article, I will attempt to combine distant and close reading and showcase how such hybrid reading approaches may provide new insights into historical corpora.
