Catalogue Note

This is a reissue of Barchusen's Pyrosophia of 1698, "a formal, systematic textbook that deals with the principles of chemistry, both theoretical and practical, and then attempts to demonstrate their applications to natural philosophy, medicine, metallurgy, and alchemy" (DSB I, p.451).

The folding plate depicts the chemistry laboratory at the University of Utrecht where Barchusen was professor, and another four of the plates show chemical apparatus. The rest contain 78 symbols representing alchemical processes.
