Among the many treasures held at the John Rylands Research Institute and Library, German MS 3, The Sammlung Alchymistischer Schriften, stands out as one of the most enigmatic, intriguing and visually stunning manuscripts in the collections.
Dated to 1767, this 18th-century volume is filled with Hermetic texts, striking alchemical imagery, and a mythical narrative that weaves together secrecy, immortality, and the transmutation of metals. It also carries a storied provenance, featuring a cast of colourful historical figures. During a recent placement at the Rylands, I undertook the task of enhancing its metadata for the Manchester Digital Collections (MDC) platform, working alongside metadata specialist Ourania Karapasia.
Digitised and made available through MDC, German MS 3 is part of a curated set of special collections presented with scholarly context and structured metadata, following the Text Encoding Initiative (TEI) guidelines. TEI allows us to describe manuscripts not just in terms of their content, but their structure, materials, provenance, and interpretive nuances.
The text opens with a title page (Fig. 1) bearing the name Theobaldo Corsini, who is said to have “left behind” the work to his heir, friend, and student, Johann Joseph Hubert, Baron von Conrath. These figures, definitely pseudonymous or totally fictitious, reflect a common feature of early modern alchemical writing, in which legendary or fabricated identities were used to convey mystical authority.
Conrath is described as having achieved the Philosopher’s Stone four times between 1460 and 1713, over a lifespan of 283 years. These claims, though fantastical, are emblematic of alchemical traditions, where symbolic truth often supersedes historical fact.

Left behind by Theobaldo Corsini To his heir, friend, and student, Johann Joseph Hubert, Baron von Conrath, who worked on it four times during his 283-year lifespan: in 1460 in Florence, 1508 in Koblenz, 1604 in Strasbourg, and 1713 in Vienna.
Various alchemical tools including flasks, retorts, and crucibles, pestle and mortar are scattered throughout emphasising practical alchemy and laboratory work. Johann Reuchlin’s ‘Pentagrammaton’ or five-letter name of Christ YHSVH at the bottom. The images of the three alchemical authorities feature, at the top Hermes Trismegistus, Morienus on the left and Geber on the right.
The manuscript’s most distinctive feature is the series of 37 full-page miniatures, executed in brilliant colour throughout the volume (Fig. 2). These illustrations present a complex visual grammar of planetary spirits, hybrid creatures, mystical emblems, and allegorical figures. Their meanings are deliberately obscure. Alchemical art is rarely literal; instead, it operates through metaphor and transformation, inviting contemplation rather than offering clear answers. Some folios depict heavenly spheres over alchemical vessels; others show crowned figures, dismembered animals, or symbolic marriages, imagery drawn from a deep visual tradition shared across European alchemical texts.
This scene depicts the personifications of the three Paracelsian principals of matter, the ‘Tria Prima’, in a hot tub. Three crowned figures; the White Queen (Salt), Red King (Sulphur), and a multicolured Mercury in the centre. The circular tub acts as the ‘vas Hermeticum’, the sacred alchemical vessel, where dissolution and rebirth take place. Behind them, a tall tree symbolizes the Tree of Life in an ornate garden, surrounding the bath white and red rose bushes evoke the Rosicrucian theme of duality, white for purity and lunar energy, red for transmutation and solar force.
Describing these images required more than conventional cataloguing. To support interpretation, I consulted many secondary literature sources, the wonderfully in-depth Alchemy Website and reviewed two detailed YouTube commentaries dedicated to the manuscript’s illustrations. I also used ChatGPT to generate hypotheses about the iconography, which proved to be wildly inaccurate to begin with. I then verified and corrected using established scholarly sources.
The manuscript’s provenance offered another fascinating avenue of intrigue. We don’t know where it first originated. However, a translation of the text on page 2v offers a clue, pointing to a library of the mysterious society of Rosicrucians:
“Out of grace and special friendship, and upon taking the customary oath of secrecy and safekeeping, the work was granted from the invaluable archive of the very renowned and highly learned Philosophical Society of the Gentlemen of the Rosy Cross, along with their coat of arms, on the 1st of January, 1767.”
The first known purchase date is hidden on a blank front page (Figs. 1 & 2). It was acquired in 1868 by Charles F. Zimpel, an engineer and occultist with interests in esoteric materials and architecture from Johann Scheible. Scheible was an antiquarian bookseller and publisher based in Stuttgart, best known for his popularisation of occult and mystical works in 19th-century Germany. An inscription on the first page of the manuscript was recovered using Multispectral Imaging (MSI) in the Rylands Heritage Imaging Lab. By capturing images in the infrared spectrum (850nm–940nm), the faded ink became legible, confirming the date of purchase and the price of 130 florins.
Another imaging session using the Selene Photometric Stereo System (PSS) focused on surface textures, revealing a previously illegible book stamp hidden beneath insect damage and paper remnants. This revealed the text had once been in the hands of another 19th-century dealer in occult books, Carl Helf.
Archival research led me to another discovery, filling in a gap of the manuscript’s history. Two letters in the Crawford Papers held at the National Library of Scotland talk of an ‘eccentric collector’, Mr. Calvert:
“I have seen in my life many strange individuals, but I never knew a more extraordinary man than Mr. Calvert, Civil Engineer; he professes to be a descendant of Lord Baltimore’…. “Mr. Calvert is a man of 63, in his youth he went to Australia, as one of the earliest gold-seekers. He returned with — as he says — 90,000£ worth of gold. He then became a book collector, buying books & MSS. on alchemy and early printed works”.
Wallace, Albert. (1890). Jottings referring to the early discovery of gold in Australia : and some remarks relative to the veteran gold miner John Calvert.
The manuscript was sold in 1878 by John Frederick Calvert, and online research confirmed his identity as a self-styled aristocrat, engineer, gold prospector and mineral dealer, described elsewhere as a genius, swindler, fantasist, and a notorious rouge of Victorian England with a long history of questionable dealings. Calvert sold the manuscript to Bernard Quaritch, who shortly after sold it to the 25th Earl of Crawford for £50, forming part of the Bibliotheca Lindesiana, subsequently sold to Enriqueta Rylands, now in the John Rylands Library.
What this project revealed is that even a single manuscript can demand expertise across languages, technologies, and scholarly disciplines. From interpreting alchemical symbolism to encoding TEI-compliant metadata, the process was a reminder that manuscript description can be as much a creative and interpretive act as it is a technical one.
The digitised German MS 3 is available on MDC to readers worldwide, offering access to a document that remains, as ever, full of secrets.
