The Golden Calf, Which the World Adores, and Desires

This work offers a glimpse into the secretive world of 17th‑century alchemy, where the boundary between chemistry and mysticism was still fluid. Written originally in Latin and later rendered into English, the author recounts a striking experiment performed in The Hague in 1666, in which a lump of lead was said to turn instantly into gold by means of a tiny fragment of the legendary Philosopher’s Stone. The narrative blends meticulous observation of the fire and the material with the lofty language of a learned physician addressing his learned peers.

The treatise is addressed to several distinguished physicians of the time, presenting the author’s modest testimony as a gift to fellow seekers of the “Vulcanian anatomy.” Interwoven are conversations with a shadowy figure called Elias the Artist, whose cryptic instructions hint at a broader spagyric system. Readers interested in the early development of chemical theory, the cultural allure of transmutation, or the literary style of early modern scientific writing will find this compact manuscript both intriguing and thought‑provoking.
