This paper analyzes the development of the concept of alkahest from its origins in the Paracelsian corpus to its mature form in the works of Joan Baptista van Helmont (1579-1644) and his successors. Historians of science have usually focused on the chemical aspects of the alkahest, taking into account especially the claims that it was a substance capable of dissolving all kinds of matter. This paper shows the medical implications of the alkahest: it was not only a "solvent," but an important means of revealing nature's secrets and of producing medicines. The properties ascribed to the alkahest fit perfectly within Helmontian theories about matter, disease, and cure.
This article considers two paintings by the English painter, Joseph Wright of Derby (1734-97), 'An Experiment on a Bird in the Air Pump' and 'The Alchemist in Search of the Philosopher's Stone' as painterly reflections on the early industrial culture. Particularly interesting in the "Experiment on a Bird" is the broad spectrum of spectator's reactions to the experiment; this can be related to the contemporary debate on the contextualization of science.
