Abstract: This paper defines the nature and extent of transmutation theory in the Greek alchemical corpus as found in the texts attributed to Zosimus of Panopolis, “the philosopher Synesius,” and “the philosopher Olympiodorus of Alexandria.” By transmutation theory, I understand all explicit attempts made by Greek alchemical writers to explain how one substance can be entirely transformed into another.

Aaron Kitch situates the Ripley scrolls in the context of English alchemy in the sixteenth century, especially the tradition of emblematic alchemy and John Dee’s efforts to establish George Ripley as England’s chief alchemical authority. He analyzes the pattern of imagery on the scrolls in relation to the ancient and early modern philosophy of generation, which focused on questions about sexual reproduction and the emergence of new matter in nature.

'On close examination Gabriele Ferrario discovered it was in fact a collection of alchemical recipes. What makes it special, compared to many other alchemical recipes in the Genizah, is that there are not only technical instructions but they reference in quite a lot of detail books of Arabic alchemical literature – works from the Jabirian corpus.'

Surrealist artist Max Ernst defined collage as the "alchemy of the visual image." Students of his work have often dismissed this comment as simply a metaphor for the transformative power of using found images in a new context. Taking a wholly different perspective on Ernst and alchemy, however, M. E. Warlick persuasively demonstrates that the artist had a profound and abiding interest in alchemical philosophy and often used alchemical symbolism in works created throughout his career.

Can alchemy be described as a protoscience? Do ancient texts with obscure formulas and procedures describe mystic rituals and allegoric visions? Or do they record instructions to carry out real scientific experiments? In other words, can alchemy be considered the ancestor of chemistry?

A group of scholars at the University of Bologna comprising philologists, historians of science, and chemists has attempted to answer these questions. To do so, they not only revived and studied ancient alchemical texts in detail but also put the described procedures into practice in the laboratory. The results of this interdisciplinary work - developed within the AlchemEast ERC project awarded to Prof. Matteo Martelli, Department of Philosophy and Communication Studies - have been published in the journal PNAS.

I've just been reading about Arthur Machen. It's thought that this charming article about alchemy in Household Words first inspired his interest in esoterica at the tender age of 8:

The Alchemy of Glass Counterfeit, Imitation, and Transmutation in Ancient Glassmaking

Marco Beretta
Published 2009
The book illustrates how glass played an important role in ancient technical and alchemical literature and how the chemical operations devised to improve glass-making inspired alchemists to better define the theoretical boundaries of their discipline and, more specifically, the notion of transmutation.

"Any student of history can tell you there is a myriad of professions that no longer exist due to technological advancement, societal trends, or some combination of the two. One such profession is alchemist, which was a term for the earliest students of chemistry, though they didn’t know it at the time. Potion Craft: Alchemist Simulator developed by niceplay games and published by tinyBuild gives a peek into what that lifestyle could have been like in ye olden times."

I recently found this rather puzzling alchemical emblem. I can't recall seeing anything quite like it
It is a folded parchment sheet in

University of Kassel, 2° Ms. chem. 24

It is entitled, Spherae sive Compassi mineralis Nova inventio  (A New Discovery of the Mineral Sphere or Compass)

It was created by Justus de Buschia, probably in 1552.


Six rays stream down from heaven and are being collected in a hemispherical vessel. It has a number of holes in its base, and beneath this, on the platform supporting the hemisphere, there are six circular discs. The rays from above shine through the holes onto these discs, which are labelled, Iovis, Solis, Lunae, Martis, Saturni, and Veneris. These discs each bear a symbol that I cannot quite make out.
