Who was John Dee—the Tudor polymath who advised Elizabeth I, mapped the heavens, spoke (he believed) with angels, and penned a landmark preface to Euclid? Historian and writer Rachel Morris joins to unpack Dee’s strange, brilliant world at the fault line between Renaissance “natural magic” and the birth of modern science. We explore why astrology was respectable, what “as above, so below” meant to learned magi, how printing turned libraries into engines of ideas, the hazards of practicing magic in an age of heresy trials, and why Dee still feels uncannily modern. We also touch on his years in Prague, his uneasy return to England, and the beautiful—if perilous—idea that the cosmos is alive with meaning.
Rachel’s new book The Years of the Wizard: The Strange History and Home Life of Renaissance Magicians (Duckworth) is out now. Please support independent bookshops or buy direct from the publisher.

John Dee and the Beautiful Logic of a Magical Universe
John Dee’s reputation tends to arrive shrouded in incense: scrying mirrors, angelic alphabets, whispers of alchemy. Yet to his Tudor contemporaries, Dee was not a sideshow mystic but a learned man—mathematician, linguist, navigator, astrologer—whose curiosity pressed at the edges of what could be known. He stood on a narrow ridge between two worlds: one we now call “magic,” the other we recognise as early science.
This essay explores that ridge—how Dee thought, the intellectual weather he breathed, the risks he ran, and why his mind still feels startlingly contemporary.
A Renaissance Mind on the Boundary
Dee believed the universe was governed by intelligible forces. Like a proto-scientist, he wanted to understand them; like a magician, he believed they could be addressed and directed. In the 16th century those aims were not contradictory. Astrology sat in university curricula; medicine drew on planetary correspondences; mathematics was a sacred grammar of nature. Dee’s celebrated work on Euclid (he wrote a major introductory preface for an English edition) made him a champion of number as the key to creation’s order.
At the same time, he pursued angelic counsel. For Dee, angels were not fairy-tale beings but intelligences within a divinely structured cosmos. If creation spoke in a lawful language, why shouldn’t its stewards answer a learned man’s questions about first principles—when the world began, how it would end, and according to what patterns it ran?
To modern ears that double stance sounds paradoxical. In Dee’s England it was a single project.
“As Above, So Below”: How a Magical Cosmos Worked
Two ideas help decode Dee’s worldview.
First, “as above, so below.” The heavens and the sublunary world were mirrors, macrocosm and microcosm. A comet was not a spectacle without consequence; it signified. Planetary motions and earthly events belonged to the same grammar. To cast a horoscope was not to dabble in superstition; it was to read a text God had inscribed on the night.
Second, the agency of celestial influences. Learned astrology imagined stars and planets issuing “rays” that touched bodies and temperaments. Your natal configuration spoke because the sky was active. The question was never whether the heavens affected life, but how they did so and to what ends a wise person might apply that knowledge—ethical, medical, political.
Set against that logic, Dee’s “angelic conversations” look less like a break with reason than a determined extension of it: if the cosmos is a book, angels are its native readers.
Books, Letters, and the Printing-Press Wind
Dee adored books. He built one of England’s great private libraries and kept careful catalogues of his holdings. Crucially, he lived just after the printing revolution. Within a few decades of Gutenberg, presses flowered across Europe; a tidal surge of Latin and vernacular volumes turned scholars’ rooms into crossroads. Letters circulated semi-publicly; treatises leapt borders in saddlebags.
That medium mattered. Plato, Neoplatonism, Hermetic texts, cabalistic speculation—materials that had filtered slowly through scriptoria now spread rapidly in printed form. Dee’s mind was fed by this abundance. The Renaissance passion for recovering antiquity did not feel antiquarian; it felt like the cutting edge. To be “modern” was to be newly intimate with the ancients.
Court Favor, Church Suspicion
Practicing magic, even “natural magic,” was always precarious. Class, gender, and timing shaped outcomes brutally. An upper-class male scholar might survive controversy that would consume a poorer woman. Still, the line was thin. Giordano Bruno was burned in Rome; English magi learned to watch their words.
Dee’s fortunes rose because his learning was useful—especially to a monarch. Elizabeth I liked clever men and cultivated a scholarly persona herself. An astrologer could read auspicious moments, interpret ominous sky-signs, and (crucially) forward political hopes in the reassuring language of the stars. Dee could also map coasts, advise navigators, and dream imperial dreams. That intellectual versatility, more than occult glamour, explains his access.
Yet favour was fickle. After his Prague sojourn in the 1580s, he returned an old man into a chillier climate, took a post in Manchester that proved unhappy, and died in straitened circumstances. A life spent pursuing the deep grammar of the world did not guarantee worldly reward.
The Ethics and Psychology of “Struggle”
One reason Dee’s world still unsettles is its frank recognition that ideas have psychic force. From self-criticism in monastic cells to learned “examinations” of conscience among early modern intellectuals, Europeans treated interior life as a site of moral and epistemic struggle. In more radical movements—whether revolutionary or religious—public rituals could demand confession, denunciation, and remaking. Dee’s magic was gentler than that, but it was born into a culture that believed minds could be reshaped, purified, or corrupted by practices of thought.
Seen this way, the magician’s work—prayer, fasting, disciplined study, the “polishing” of an inner mirror to catch celestial light—rhymes with the scientist’s cultivated habits: patience, method, careful attention. Different theologies, eerily similar psychologies.
Why John Dee Feels Modern
Three things make Dee feel close.
1) The hunger to unify knowledge. Dee wanted a total picture: mathematics, cosmology, language, metaphysics. Today we chase “theories of everything,” not angelic alphabets, but the impulse is recognisable.
2) A living universe. Dee treasured ideas (from Plato and his heirs) that the cosmos possesses a kind of soul, that matter and meaning are entangled. You need not share the metaphysics to sense the appeal. Even hard-headed physicists sometimes describe a world stranger than common sense allows; the intuition that reality is richer—and more relational—than appearances remains powerful.
3) The enduring pull of pattern. Humans are meaning-makers. When uncertainty surges, magical thinking resurfaces—not because people are credulous, but because anxiety hunts for form. Pandemic years showed how fast rumor, symbol, and system can reorder experience. Dee reminds us that the desire to read the sky, to ask what time it is in the grand scheme of things, is human before it is “scientific” or “superstitious.”
What, Finally, Was the Point?
It is tempting to judge Dee by the yardstick of later science and find him wanting. That would miss the point. He was not a failed Newton; he was a successful Renaissance magus, a man who treated mathematics as prayer and experiment as devotion. He helped carry Europe from a sacramental cosmos into a lawful one without surrendering wonder. He believed the world had a grammar—and that we might learn to speak it without violating humility before its maker.
That double aspiration—to understand and to revere—may be Dee’s deepest legacy. In an age of clever cynicism, it is no small thing to recover a version of curiosity that is also a posture of care.
