The Book of Soyga, also titled Aldaraia, is a 16th-century Latin treatise on magic, one copy of which was owned by the Elizabethan scholar John Dee. After Dee's death, the book was thought lost until 1994, when two manuscripts were located in the British Library (Sloane MS 8) and the Bodleian Library (Bodley MS. 908), under the title Aldaraia sive Soyga vocor, by Dee scholar Professor Deborah Harkness.

"Alongside the importance placed on the art of conversation in the eighteenth century, salon society took an amateur’s interest in science and philosophy. Also
prevalent in this period, was the continued significance of the pursuit of gold. This was observed in literature also, and it became a common theme found in
seventeenth- and eighteenth-century airs. The air à boire, ‘Pour guérir sans retour la vive bléssure’, whose text was written by an anonymous author, illustrates this... 

As well as the loose reference to alchemy in the air à boire discussed above, ‘Ah que l’homme est sçavant’ presents us with a particularly unusual air on this very topic. The text, by Pinel, clearly points to alchemy, through its basic description of the alchemic process:

L’on fixe le mercure on a beau me le dire,
Dans un creuset je vois mettre de l’or
Et de soufleur confus jamais ne l’en retire."

"Describing the relationship between the alchemical oblong square and the electrical circuit of the brain, the author details the operative process of the Philosophers' Stone, likening it to the servomechanism of the third eye located between the twin pillars of the cerebral hemispheres. He explores how to navigate the twin pillars of the brain to find equilibrium—the third pillar. When the energies of our third eye are in equilibrium, we resonate as a harmonic waveform generator, and he shows how this can be achieved through meditation and the synchronizing vibration of vocal mantras."

"The Alchemist". A short story by a teenaged H P Lovecraft.
 
"When at last I turned and faced the seat of the sound, my eyes must have started from their orbits at the sight that they beheld. There in the ancient Gothic doorway stood a human figure. It was that of a man clad in a skull-cap and long mediaeval tunic of dark colour. His long hair and flowing beard were of a terrible and intense black hue, and of incredible profusion. His forehead, high beyond the usual dimensions; his cheeks, deep-sunken and heavily lined with wrinkles; and his hands, long, claw-like, and gnarled, were of such a deathly, marble-like whiteness as I have never elsewhere seen in man. His figure, lean to the proportions of a skeleton, was strangely bent and almost lost within the voluminous folds of his peculiar garment."

Thesis by Lynette Dawn Grant.

"The examination of alchemical art in Europe during
the sixteenth and seventeenth centuries brings to light the
fact that the symbols employed invariably had multiple meanings,
but embodied a consistent polarity.
In pictorial representation the secret meanings implied
in the symbols were sometimes less concealed, and the possibility
of gaining more insight into the true nature of alchemy is therefore
probably greater by this type of examination than by scrutiny of
literary records alone. The process not only reveals something of
the nature of alchemy but gives an indication of the attitudes of
the various artists to alchemy and the degree to which they were
truly initiated into the secrets of the alchemical doctrine."

The Alchemy of Paint is a critique of the modern world, which Spike Bucklow sees as the product of seventeenth-century ideas about science. In modern times, we have divorced color from its origins, using it for commercial advantage. Spike Bucklow shows us how in medieval times, color had mystical significance far beyond the enjoyment of shade and hue.

Each chapter demonstrates the mindset of medieval Europe and is devoted to just one color, acknowledging its connections with life in the pre-modern world. Colors examined and explained in detail include a midnight blue called ultramarine, an opaque red called vermilion, a multitude of colors made from metals, a transparent red called dragonsblood, and, finally, gold.

Thesis by Susan Hemmens. Several alchemical references, e.g. William Petty.

"This thesis offers a re-evaluation of the activities and mindset of a community of
natural philosophers who described themselves as curious: the members of the
Dublin Philosophical Society (1683—1709) (DPS) and their circle in Ireland and
further afield. Although they sometimes perceived themselves as being on the
periphery of the learned world, members of the DPS engaged self-consciously and
with reflection in that world. The thesis argues that the DPS, along with like-minded
individuals in Ireland and abroad, participated in the making of knowledge in ways
that they regarded as new. By way of a series of case studies, the thesis delineates the
influences on the DPS, details the workings of the society, and discusses the reception
of its outputs by peers."
