Paracelsus (1493-1591)

Paracelsus is the common name for the Swiss alchemist Filipe Aurelio Teofrasto Bombastus von Hohenheim which was born in Zurich, in 1493, and died in Salzburg, in 1541.

Its education, guided by his father, was strongly biased to the study of Medicine and used the basic concepts of Chemistry. One of the inspiring principles was the concept of "arqueu", a kind of the so-called caloric thought to be a fire resident in the Earth's core, that would govern the metal forming, the vegetation, etc.

For Paracelsus and von Helmont, the "arqueu" was the main origin and constituent of matter and thought, therefore explaining the development of the living creatures.
