Give me a list of 40 of the lesser known sources of magic as a precursor to experimental science considered by Lynn Thorndike in his classic study
Below is a list of 40 lesser-known sources Lynn Thorndike discusses (or draws upon) in A History of Magic and Experimental Science. These are not the famous marquee names (Albertus, Roger Bacon, Ficino, etc.) but rather minor, obscure, or understudied authors, compilations, and textual currents that Thorndike used to reconstruct the long prehistory of experimental science through magical, astrological, and technical literature.
I focus on sources that are (a) genuinely mentioned by Thorndike, (b) often overlooked in modern summaries, and (c) represent the “background radiation” of medieval natural magic, occult experimentation, and technical lore.
Summaries ten per response
Great — here are the first 10 summaries, written in a style that reflects Thorndike’s own concerns: transmission, manuscript culture, credulity vs. rationalism, and the continuity he saw between “magic” and the emergence of experimental habits of mind.
(Each entry: what the text is, what kind of magic or proto-science it represents, why Thorndike considered it historically important.)
If you'd like, I can continue with 11–20 in the next message.

Here are 20 takeaways from Thorndike’s overall argument, each followed by how later scholarship has confirmed, revised, or fought with that move.
I’ll do it as “Thorndike → later debate” for each point.
Thorndike:
His central move is that you cannot write a serious history of medieval and early modern science without magic, astrology, and alchemy. They’re not peripheral superstitions; they’re integral to how people investigated nature. citeturn0search0turn0search28
Later scholarship:
This has basically won. Historians of alchemy and “occult sciences” (Principe, Newman, Pingree, etc.) explicitly position themselves as extending or correcting Thorndike rather than rejecting him. Principe’s “Alchemy Restored” and The Secrets of Alchemy are explicit projects to reinsert alchemy into mainstream history of science, arguing it was a key experimental discipline. citeturn0search22turn0search2
Thorndike:
He insists medieval magic, astrology, and alchemy follow a coherent internal logic—they’re not random insanity. Practitioners reasoned from premises inherited from Aristotle, Galen, Scripture, and late antique Platonism.
Later scholarship:
Kieckhefer’s “Specific Rationality of Medieval Magic” explicitly names Thorndike and builds on this idea: magic has its own specific rationality, distinct but not irrational. citeturn1search17turn1search5
Hanegraaff’s work on esotericism likewise argues that so-called “rejected knowledge” is organized and intellectually serious, shaped by polemics rather than being inherently irrational. citeturn1search32turn1search36
Thorndike:
He argues that “experimental science” did not suddenly appear in the 17th century; its roots lie in medieval recipe traditions, natural magic, and alchemy—people trying things out in the lab, garden, workshop, or pharmacy. citeturn0search0turn0search24
Later scholarship:
Newman’s Atoms and Alchemy and his broader work on “chymistry” sharpen this: specific alchemical traditions developed operational criteria for elements and corpuscles, directly feeding later mechanistic matter theory and Boyle’s chemistry. citeturn0search7turn0search23
Principe’s reconstructions of alchemical experiments strengthen Thorndike’s intuition with lab evidence: many alchemists really were doing sophisticated experimental work. citeturn0search14turn0search22
Thorndike:
Much of his “argument” is actually a massive bibliographic and manuscript map: identifying, dating, and describing hundreds of texts (including weird things like Liber vaccae). This is an implicit claim: before theorizing, you must know what the sources are. citeturn1search0turn1search29
Later scholarship:
Modern work on Liber vaccae, Picatrix, ars notoria, etc., often begins by saying “Thorndike first mapped this terrain.” A good example: Van der Lugt on Liber vaccae explicitly credits Thorndike’s pioneering manuscript work. citeturn1search29
So on this front, he’s still the big scaffolding behind more interpretive work.
Thorndike:
He treats astrology not as marginal superstition but as a core mathematical science of the medieval curriculum: built on astronomy, geometry, and complex calculations, and heavily used in medicine and politics. citeturn0search24turn0search33
Later scholarship:
Modern historians of astrology (e.g. Pingree and those cited in “Notion of Occult Sciences” discussions) broadly agree that astrology was a technical science in its own terms and a central part of learned culture. citeturn1search33
The controversy now is less whether it was central and more about how to balance its intellectual, social, and political functions.
Thorndike:
He pushes hard that alchemy involved genuine laboratory work, not just weird symbolism or psychological allegory. He links it directly to the emergence of experimental methods, especially in the 16th–17th centuries (Boyle, etc.). citeturn0search24turn0search17
Later scholarship:
Principe and Newman have basically turbocharged this, arguing that alchemists were central to the development of chemistry, not a sideshow. They show that alchemists developed corpuscular theories and techniques that Boyle and others directly used. citeturn0search2turn0search23
The controversy is now mainly with older, more dismissive views (e.g. Jungian “it’s all allegory”), not with Thorndike.
Thorndike:
He repeatedly shows clerics copying, using, and sometimes defending magical texts (Solomonic, ars notoria, angel magic, etc.). The Church represses some things, but is also a major carrier of magical knowledge. citeturn1search25turn0search24
Later scholarship:
Kieckhefer’s Magic in the Middle Ages and work on Christian ritual magic make this much more nuanced: ecclesiastical ritual and “magic” sit on a continuum; inquisitors, theologians, and ritual magicians share assumptions. citeturn1search5turn1search9
Hanegraaff likewise shows that “esotericism vs. orthodoxy” is a constructed boundary shaped by confessional polemics. citeturn1search32turn1search16
Thorndike:
He is fascinated by “marvels books” and miracle-like phenomena (strange stones, monstrous births, odd optical effects). He treats wonder as a driver of investigation: marvels prompt classification and causal speculation. citeturn0search0turn0search24
Later scholarship:
Daston & Park’s Wonders and the Order of Nature gives this its full theoretical spin: wonder and “wonders” structure natural inquiry between 1150 and 1750, and the style of wonder changes over time. citeturn1search14turn1search1
They move beyond Thorndike’s mostly descriptive approach, arguing that the affect of wonder is central to how naturalists conceptualized “nature” itself.
Thorndike:
He devotes huge space to writers like Vincent of Beauvais, Thomas of Cantimpré, Albertus, and pseudo-Albertine compilations, arguing that encyclopedias and “books of secrets” are crucial sites where magical and scientific lore are reorganized and conserved. citeturn0search24turn0search28
Later scholarship:
Recent work on “books of secrets,” household recipe books, and artisanal knowledge (Smith, Eamon, etc.) echoes this but pushes it down into craft and domestic contexts as well. Daston & Park also treat collections of wonders as epistemic instruments, not just trivia dumps. citeturn1search14turn1search18
Thorndike:
His archive is overwhelmingly Latin learned texts in institutional libraries. He’s explicit that he’s following the “learned tradition,” which means he underplays vernacular, oral, and popular magic.
Later scholarship:
Kieckhefer, Bailey, and others put much more emphasis on social history, vernacular magic, and legal records, showing how elite and popular practices intersect. citeturn1search5turn1search31
So Thorndike’s framework is still influential, but his archive looks narrow compared to current work that includes archaeology, material culture, and judicial sources.
Thorndike:
Despite his sympathy for medieval thinkers, he still has a fairly progressive narrative: over time, the “experimental” side of magic is retained and rationalized; the more superstitious or demonic elements drop away, culminating in “real science.”
Later scholarship:
The “Scientific Revolution” literature tends to be more suspicious of simple progress narratives. Daston & Park, Shapin, Dear, etc. stress contingency and plurality of scientific styles rather than a straight line of progress. citeturn1search1turn1search26
Principe and Newman accept continuity but downplay any triumphalist story that sees magic purely as something to be transcended. citeturn0search22turn0search23
Thorndike:
He’s classic early-20th-century intellectual history: ideas, texts, and learned figures dominate; printing, patronage, artisanal economies, and state formation play a minimal role.
Later scholarship:
Historians like Newman (with attention to artisanal practice), Principe (recreating lab work), and the broader “practice turn” in history of science shift focus to labs, workshops, courts, and economies. citeturn0search14turn0search23
Historians of magic and medicine similarly integrate legal, economic, and gendered contexts, complicating Thorndike’s text-heavy portrait.
Thorndike:
He tends to classify magic alongside astrology and alchemy as occult sciences, distinct from theology and devotion. Religious frameworks matter, but he treats magic mainly as a form of natural philosophy rather than as religious practice. citeturn1search0turn0search24
Later scholarship:
The esotericism field (Faivre, Hanegraaff, etc.) shows that religion, philosophy, and “occult science” are deeply entangled, and that “occult sciences” are themselves a category produced in early modern polemics and Enlightenment historiography. citeturn1search32turn1search20
Kieckhefer’s work on Christian ritual magic also blurs Thorndike’s neat line between theology and occult practice. citeturn1search9turn1search5
Thorndike:
He constantly notes how medieval thinkers assume occult qualities—hidden virtues in stones, herbs, metals—that produce effects not obvious from surface properties. For him, this is the conceptual core linking magic to natural philosophy. citeturn0search0turn0search28
Later scholarship:
New work on “occult qualities” (in both scholastic philosophy and chymistry) often shows that these are serious theoretical entities, not lazy gap-fillers: they’re linked to debates on causality and matter theory. Newman’s work, for example, shows alchemists turning occult behavior into micro-mechanistic explanation. citeturn0search23turn0search15
Thorndike:
He treats medical astrology, image magic, and talismans as major fields where celestial theory and practical health care meet. They show how far “scientific” medicine is intertwined with astral lore. citeturn0search24turn1search21
Later scholarship:
Historians of medicine and astrology generally confirm this integration and deepen it: studies of astral medicine, hospitals, and learned physicians stress that astrological diagnosis and timing were routine, not fringe. The present debate is more about regional differences and reception than about whether Thorndike was right to see this as central. citeturn1search33turn1search5
Thorndike:
He reads early modern figures like Boyle, Kepler, and Newton as transitional: still soaked in astrology, alchemy, and biblical chronology while also pioneering “modern” methods. Science grows out of magic rather than abruptly replacing it. citeturn0search17turn0search29
Later scholarship:
This idea has been enthusiastically taken up and sharpened—especially for Boyle and Newton. Principe’s Aspiring Adept argues that Boyle was actively alchemical; Newman shows how chymistry underpins his mechanical philosophy. citeturn0search10turn0search23
For Newton, studies of his alchemy and theology likewise echo Thorndike’s intuition that the “founders” of modern science are deeply entangled with magical and theological projects.
Thorndike:
He is quite anti-romantic about Hermetism, Rosicrucianism, and similar trends. He doesn’t deny their importance, but he resists reading them as bearers of timeless mystical wisdom. For him they’re historical, often confused, sometimes credulous.
Later scholarship:
Post-Yates debates about Hermeticism and the “Yates thesis” (Renaissance Hermetism as root of modern science) often use Thorndike as an earlier, more skeptical foil. Esotericism scholars today try to steer between Yates-style over-celebration and Thorndike’s cooler stance, emphasizing both the cultural power of Hermetic/esoteric currents and the dangers of mythologizing them. citeturn1search16turn1search32
Thorndike:
By spending energy on Liber vaccae, obscure Solomonic manuals, talismanic tables, cosmetic books, and secret books, he implicitly argues that minor magical texts are structurally important, not just curiosities. citeturn1search29turn1search25
Later scholarship:
This has become standard; scholars now write whole monographs on things like Picatrix, Liber vaccae, ars notoria, or individual grimoires. Thorndike’s sense that the “weird little stuff” reveals the texture of actual practice is very much in line with current micro-historical and material-culture approaches. citeturn1search25turn1search21
Thorndike:
Although he doesn’t use the language, his practice shows magic as a crossroads where medicine, astronomy, theology, philosophy, and artisanal crafts meet.
Later scholarship:
Kieckhefer literally describes magic as a “crossroads” of medieval culture, making explicit what Thorndike does implicitly. citeturn1search23turn1search35
Daston & Park similarly treat marvels as points where natural philosophy, theology, and courtly culture intersect. citeturn1search14turn1search18
Thorndike:
His eight volumes are essentially a giant historiographical infrastructure project: map the terrain of texts, show that magic belongs in the history of science, hint at continuities, and leave reinterpretation to the future.
Later scholarship & controversies:
Modern debates about:
