Mylius: Philosophia Reformata

[Paul Ferguson]

"The physician Johann Daniel Mylius illustrated his edition of the 15th-century Scala philosophorum (Ladder of the Philosophers) with twelve alchemical engravings, including the Chemical Wedding. The sequence shown here was originally designed for a later work, the Twelve Keys of Basil Valentine, which describes a different chemical approach, based on antimony. Mylius has retrofitted the sequence by adding titles that correspond to the first four steps of the Scala: Calcination, Dissolution, Separation, and Conjunction."
