The collected alchemical works of Dorothea Juliana Wallich (1657-1725) represent the largest existing body of writings from a practicing female alchemist. Born in Weimar, Germany, Wallich worked in an apothecary, owned a mine in Saxony, made contributions to the chemistry of cobalt chloride, and recei ved the patronage of the Thuringian aristocracy. Following in the footsteps of figures such as pseudo-Cleopatra, Maria Prophetissa, and Theosebeia, Wallich's alchemical worldview encompassed laboratory, medicinal, philosophical, and religious alchemy, all of which come together in this fascinating trilogy of writings. Translated into English for the very first time, this dual-language edition presents the original German texts alongside a facing-page translation by Dr. Alexander Kraft, together with scholarly introduction and commentary. This 2025 Rubedo Press publication commemorates the 300th anniversary of Wallich's death.
