“The drawers at the Making and Knowing Lab, at Columbia University, have labels rarely seen outside a Harry Potter novel: ‘Ox Gall,’ ‘Spiderwebs,’ ‘Powder for Hourglasses,’ ‘Dragon’s Blood.’ The denizens of the lab re-create old recipes from alchemy-era texts—primarily of the sixteenth century—and this brings them into contact with some unusual ingredients. On a recent Monday morning, Joel Klein, a redheaded history-of-science postdoc who studies Isaac Newton’s alchemical work, sniffed a bag of flakes labelled ‘Rabbit-Skin Glue.’ ‘It smells like skin,’ he said. Another sniff. ‘Although I’m not sure what a sommelier would say.'”

“IN A LIGHT-FILLED ROOM in a building behind the State Museum of Prehistory in Halle, Germany, a row of tables is lined with oddly shaped glass vessels. When Christian-Heinrich Wunderlich saw them for the first time three years ago, they were in thousands of pieces, enough to fill six crates. Archaeologists had discovered the fragments during a rescue excavation in nearby Wittenberg in a niche underneath what had been a fifteenth-century monastery’s basement stairway.”

“In the dim illumination of a library devoted to protecting ancient books from light degradation, James R. Voelkel gingerly picks up a nearly 600-year-old alchemy text. Written by hand sometime around 1438, the thick tome is bound by a leather and wooden cover that is studded with metal nails in the shape of a hexagonal star lying within a circular disk. Inside, worms have eaten through small sections of the text, which features more than 500 alchemical recipes.”

“A group of Columbia University students is keeping a close watch on a bright red liquid swirling in a pot. They keep checking the temperature through masks and protective goggles. Eventually, they declare the liquid to be ready, and dip thin branches into the mixture, creating what looks very similar to pieces of coral.”

Alchemists are known for equally dreamy and practical pursuits—trying to turn base metals into gold and achieve immortality while also conducting the experiments that would lay the groundwork for modern chemistry. But it turns out the alchemists had another trick up their sleeves: speaking the language of love—and lust. On today’s show we sit down with historian Joel Klein to find out why so many alchemy texts are rife with blush-inducing romantic and sexual metaphors. Then CHF’s James Voelkel recites some of our favorite steamy passages.”

“Intrigued observers have been puzzled for centuries by the graphic portrayals of copulating bodies and hermaphrodites found in alchemical texts. Where does this imagery come from, and what does it actually mean? On May 3, 2013, CHF fellow Joel Klein explored the steamier side of alchemy.”

'I've never wanted to be a witch, but an alchemist, now that's a different matter. To invent this wizard world, I've learned a ridiculous amount about alchemy.'~J.K. Rowling The Herald, 1998

“In the Harry Potter series of books, J.K. Rowling has created an extremely imaginative and enchanting world that has captivated the minds of millions of readers. Part of that world, in fact, was not invented wholesale but was taken from the history of alchemy. For instance, in the title of the very first book (at least in the U.K. edition), Rowling mentions the philosophers’ stone, perhaps the most common subject of alchemical texts. In addition, historical alchemists such as Nicolas Flamel have characters named after them in the series. On the internet, a reader can quickly find any number of theories that use an understanding of alchemy to explain themes, characters, and imagery within the books. The historical world of alchemy is replete with fantastic imagery involving resplendent suns, dragons, griffins, hermaphrodites, homunculi, resurrections, and many other varieties even more bizarre and peculiar, providing fertile soil for multiple alchemical interpretations. Even so, alchemy is a widely misunderstood discipline. Many continue to think of it solely as a mystical or spiritual endeavor, even though we now know that major scientific figures such as Isaac Newton (1643-1727) and Robert Boyle (1627-1691) sought to transmute base metals into gold, were widely read in alchemical authors, and sometimes kept company with other alchemists. This highlights just how complex the historical world of alchemy really is, for there were many who did treat it as a mystical journey of enlightenment, many alchemists did fill their books with confusing imagery and bizarre pictures, but alchemy was also often an empirical and theoretical discipline that involved quantification, step-by-step laboratory processes, and a rich history that stretches back through the Middle Ages to the ancient world.”
