Verae alchemiae artisque metallicae, published in 1561 by Henricus Petrus, remains a primary historical source for alchemical thought largely due to the editorial efforts of Guglielmo Grataroli. Born in Bergamo in 1516, he navigated a volatile era as both a physician and a philosopher, ultimately leaving a substantial mark on the intellectual landscape of sixteenth-century Europe.
Academic Foundations and Exile
Grataroli pursued his formal education in Padua and Venice. His professional trajectory shifted significantly due to his religious convictions as a Calvinist. Seeking sanctuary from persecution, he moved through Graubünden and Strasbourg before establishing a permanent base in Basel in 1552. This transition to Basel provided him with the stability to focus on his medical practice and his scholarly editorial projects.

His most recognized work, the 1561 collection Verae alchemiae artisque metallicae, served as a crucial repository for alchemical texts. He drew extensively from the earlier De Alchemia and systematically organized a wide range of treatises. The collection prioritized works by authors such as Pseudo-Lull and Pseudo-Geber, though he notably excluded the Tabula Smaragdina and the commentary by Ortulanus from the first volume. His efforts provided a foundation for later compilations like the Theatrum Chemicum, ensuring these documents remained in circulation for subsequent generations of scholars.
Medical and Philosophical Writings
Beyond his alchemical compilations, Grataroli produced original medical and philosophical texts. In 1553, he published De Memoria Reparanda, Augenda, Servandaque, which addressed techniques for memory maintenance. He authored practical guides for travelers, such as the 1556 work Regimen omnium iter agentium, which saw an updated edition in 1563. Additionally, his 1561 text Pestis descriptio, causa signa omnigena et praeservatio focused on the analysis and prevention of the plague, demonstrating his engagement with contemporary public health concerns.
