What Is a Grimoire, Really?

The word grimoire floats through modern witchcraft practice as though everyone agrees what it means. A leather-bound personal journal. The Book of Shadows a teacher passed down. A medieval manuscript in a museum case. The red-covered paperback at the occult shop. All of these get called grimoires — and the conflation obscures something worth knowing: the grimoire is a specific historical genre with a specific history, and distinguishing the genuine article from the invention matters for how you read and use the texts.

This page is a reference to that genre. It defines what a grimoire is in the historical sense, walks the major surviving texts with honest dates and transmission histories, identifies which famous titles are not what they claim to be, and notes where the modern practice tradition diverged from the manuscript tradition. It is a map for the research desk, not a workshop manual.

The word and the concept

Grimoire is a French word, a corruption of grammaire — grammar. The evolution is direct: a grammar was a book of Latin instruction, Latin was the language of learning and of the Church, and by extension any mysterious book of obscure knowledge could be called a grammaire. The magic book picked up the corrupted form. Owen Davies, whose Grimoires: A History of Magic Books (2009) is the most thorough scholarly account of the genre, notes that the term circulated in French popular culture before it was exported as a general term for magic manuals.

What distinguishes a grimoire from other magical writing? Three consistent features run through the genre across centuries:

Instruction, not theory. A grimoire tells you how — how to construct a talisman, how to summon a spirit, how to write a protective word or letter combination, how to time an operation astrologically. Philosophical or theological argument about why magic works appears only as framing. The core is procedure.

Written transmission. The grimoire assumes text as the primary vehicle. This distinguishes it from oral traditions, where knowledge passes person-to-person and is not primarily a textual object. The grimoire can circulate; it can be copied, sold, stolen, and translated.

Claimed authority. Almost every grimoire attributes itself to an ancient or supernatural source — Solomon, Moses, Honorius, a named angel, Hermes Trismegistus. The attributed author is almost always pseudonymous. This was a convention of the genre, not necessarily the intent to deceive in a modern sense; it placed the text within a tradition of authorized wisdom and distinguished it from a mere practitioner’s notes.

Why the history matters for practitioners

The standard narrative sold in popular witchcraft writing runs something like: these texts are ancient, persecuted wisdom that survived underground through the centuries. The honest version is more complicated and, on closer examination, more interesting.

Most of the texts we call classic grimoires are neither ancient nor underground. They circulated openly — through booksellers, among scholars, in noble libraries. They were copied and sold. The Catholic Church condemned them repeatedly, which means the Church knew they existed and found them widespread enough to worth condemning. Some circulated in manuscript for centuries before going to print; others jumped almost immediately into commercial publishing. A text’s claim to be the secret wisdom of Solomon, suppressed by the Church and passed through a hidden lineage, is almost invariably a genre convention. The text is usually a few centuries old at most, compiled from other texts, and frequently spotted in a duke’s catalogue.

None of this makes the texts useless for practice. It makes them legible as human artifacts, which is the first step toward using them intelligently.

The Sworn Book of Honorius

Liber Iuratus Honorii — the Sworn Book of Honorius, also called Liber Sacer — is one of the oldest surviving medieval grimoires in Latin and one of the most important. Its date of composition is uncertain. Peterson’s critical edition notes that the text may be referred to as Liber Sacer as early as the thirteenth century, which would place it in the High Middle Ages; the manuscript evidence is sparse, and only a few copies survive.

The title refers to the oath: students were sworn to secrecy before being granted access to the text. The oath is part of the book’s self-presentation as endangered, suppressed wisdom — a convention the genre would repeat for centuries. The text attributes itself to one Honorius of Thebes, son of Euclid, a figure who is otherwise unknown and almost certainly fictional.

What is inside is substantial. The Sworn Book presents a complete system of ritual magic: how to attain a vision of God, how to communicate with holy angels, how to command aerial, earthly, and infernal spirits. Its elaborate “Seal of God” — a dense diagrammatic construction — appears in other texts and amulets across Europe, evidence that the Sworn Book was genuinely influential rather than merely collected. Davies identifies it as an important witness to the movement of Kabbalistic and Jewish mystical elements into Latin Christian learned magic.

For practitioners working in the ceremonial tradition, the Sworn Book is the oldest coherent system of angelic and spirit magic in European Latin. Its modern edition, with translation and commentary by Peterson (2016), is the entry point.

The Key of Solomon

Clavicula Salomonis — the Key of Solomon — is the most famous grimoire in the Western tradition and the one most frequently misrepresented as ancient. It is not.

The earliest known reference to a text by this name appears in Peter of Abano’s Lucidator dubitabilium astronomiae, written between 1303 and 1310 — giving us a terminus ante quem of the early fourteenth century. The oldest surviving manuscript fragment, discovered in the Biblioteca capitolare di Trento, dates to 1380–1410. An Italian manuscript held at the Bibliothèque nationale de France (BNF Ital. 1524) dates to 1446, probably translated from a Latin copy documented in the library of the Duke Filippo Maria Visconti of Pavia in 1426.

What does this mean in practice? The Key of Solomon in the form that survives is a late medieval or early Renaissance text, compiled in a Christian European context, with evident debts to Jewish mysticism (Kabbalah, Hebrew divine names) and classical demonological tradition. It is not a book of Hebrew origins or a survival of ancient Israelite religion. The attribution to Solomon is the genre convention at work.

The Key is not one text but a family of manuscripts. They vary significantly, share a recognizable skeleton — preparations, prayers, pentacles, instructions for tools and circle-casting — and show signs of continuous scribal revision and addition. Manuscripts are held in the British Library (Sloane MS 3847, among others) and the Bibliothèque de l’Arsenal in Paris.

S. L. MacGregor Mathers published the first widely circulated English translation in 1889. His edition drew on several British Library manuscripts but is not a critical edition by modern standards; it lacks a proper analysis of manuscript families, and his romantic Victorian framing influenced the text’s reception in the emerging occult revival. Practitioners using the Mathers edition are working with a Victorian mediation of a late medieval text — which is itself a legitimate tradition, so long as you know that is what it is.

The Picatrix

The Picatrix has a cleaner and more genuinely impressive pedigree than most of its competition. The original text, Ghāyat al-Ḥakīm (The Goal of the Wise), was compiled in Arabic from over two hundred sources in the latter half of the tenth century or the eleventh. The attribution to the Andalusian mathematician al-Majriti (d. ca. 1004–7) is considered pseudepigraphic — a familiar pattern.

The text was translated into Castilian Spanish in the mid-thirteenth century and then into Latin in 1256, at the court of Alfonso X of Castile, called Alfonso the Wise. The Latin text, edited by David Pingree (Warburg Institute, 1986), is the standard scholarly reference for the European tradition. The Arabic-to-Latin transmission is unusually well-documented, and the Castilian version serves as an important bridge.

What is the Picatrix? It is a manual for planetary magic: how to construct talismans keyed to the seven classical planets, how to mix the correct incenses and suffumigations for each planetary operation, how to determine the right astrological conditions, and how to summon and propitiate planetary spirits. It is also a theoretical treatise — it has more interest in explaining why its system works, in terms of Neoplatonic cosmology and astral physics, than most grimoires do.

The Picatrix sits at a genuine crossroads of traditions. It synthesizes Hellenistic astral magic, Arabic astronomical science, and late-antique Neoplatonic philosophy. It is the channel through which much of this synthesis passed into Renaissance learned magic — Ficino, Cornelius Agrippa, and others drew on the Picatrix tradition directly. A modern English translation by Dan Attrell and David Porreca (2019, Broadview Press), based on Pingree’s Latin edition, has made it accessible without the distortions of earlier popular versions.

For practitioners, the Picatrix is one of the best-sourced and historically richest grimoires in the tradition — and one of the most demanding. Its operations require working knowledge of astrological timing and planetary correspondence that goes well beyond the simplified systems in most modern correspondence books.

The Lemegeton (Lesser Key of Solomon)

The Lemegeton, also known as the Lesser Key of Solomon, is frequently discussed in the same breath as the Clavicula Salomonis, as though they are companion volumes from the same era. They are not.

The Lemegeton is a seventeenth-century compilation. It gathers several distinct parts — the Ars Goetia (demon conjurations, with the famous list of seventy-two spirits), the Ars Theurgia-Goetia, the Ars Paulina, the Ars Almadel, and the Ars Notoria — each of which has its own separate textual history. The Ars Notoria, the briefest of the component parts, is itself a much older text circulating separately under that name from at least the thirteenth century. The compilation into what we now call the Lemegeton is an early modern editorial act, not an ancient transmission.

The Goetia, the first book, achieved its widest circulation in the twentieth century through Aleister Crowley’s edition (1904), which introduced it to the occult revival with significant editorial additions. The lineage most practitioners are inheriting when they work the Goetia is, in chronological order: manuscript fragments from the seventeenth century; a nineteenth-century British Library copy; Crowley’s Edwardian edition; and post-Golden-Dawn ceremonial magic pedagogy. That is a real lineage — but calling it “ancient Solomonic tradition” papers over four centuries of documented human editorial work.

The Sixth and Seventh Books of Moses

The Sechstes und Siebentes Buch Mosis is the canonical example of a grimoire that presents itself as ancient and is not. It appeared in print in the nineteenth century in the German-speaking world, attributing itself to the biblical Moses as author of two additional hidden books beyond the Pentateuch. The text presents an elaborate system of seals, conjurations, and magical formulae, framed as secret Mosaic and Kabbalistic wisdom.

Davies gives the Sixth and Seventh Books of Moses substantial attention precisely because of its later global reach. Carried by German immigrants to North America and disseminated through cheap print editions, it became foundational to Hoodoo, Pennsylvania Dutch powwow practice, and various African diasporic traditions. Peterson’s scholarly edition (2008) documents this dissemination carefully. The text is genuinely nineteenth-century — not ancient, not medieval — but its influence on living practice traditions makes it significant in its own right.

The distinction matters: a practitioner working with the Sixth and Seventh Books of Moses in a Hoodoo context is working within a coherent nineteenth-and-twentieth-century tradition with real depth. A practitioner invoking it as a record of ancient biblical magic is working with the book’s own false advertising.

The 19th-century publishing boom

The Sworn Book, the Key of Solomon, and the Picatrix circulated in manuscript for centuries. The print revolution opened a new economy for grimoires. By the eighteenth and nineteenth centuries, cheap editions of magic books — grimoires de sorciers in France, the Petit Albert and Grand Albert, the Dragon Rouge — were sold openly at fairs and through booksellers. Davies documents this commercialization in detail, including the extent to which the books were bought by people who could not read them, or whose use of them was primarily as material objects with talismanic rather than instructional function.

The nineteenth century produced a second wave: the deliberate reconstruction and invention of ancient-seeming grimoires, often in the context of nationalist or occultist projects. This is the era of the Sixth and Seventh Books of Moses, of the early Golden Dawn’s textual borrowings, and of figures like Frederick Hockley and Mathers who edited and sometimes embellished medieval manuscripts for occultist audiences. The Victorian occult revival was simultaneously an act of recovery and an act of invention, and it is not always easy to see where one ends and the other begins.

What this means for modern practitioners

The modern practice of calling a personal magical journal a “grimoire” is a late-twentieth-century extension of the term. There is nothing wrong with it — language expands — but conflating the personal journal with the historical genre muddles both.

The historical grimoires are not personal journals. They are technical manuals, in the same genre as a surgical textbook or a musical treatise, compiled by scribes and editors with their own agendas, circulating through markets, subject to the economics of copying and printing and censorship. They carry their histories in their texts: a pentagram borrowed from an earlier tradition here, a Christian prayer bolted onto a Jewish divine name there, a sixteenth-century Italian scribe’s addition to a fourteenth-century French original over there.

Reading them as practitioners means holding two things at once: the operations they describe can be engaged seriously, and the texts themselves are artifacts that require critical reading. The one does not cancel the other.

A working library for this subject has at minimum: Davies’s Grimoires for the historical overview; Peterson’s editions for critical texts (Clavicula Salomonis, Sworn Book, Lemegeton, Sixth and Seventh Books of Moses); and Pingree’s Picatrix for the astrological magic tradition. From that desk, the genre starts to make sense — not as ancient secrets but as a living, contentious, endlessly copied argument about how to make contact with forces beyond the ordinary.

A note on fakes and reconstructions

Three texts deserve explicit mention as things that are not what they claim:

The Necronomicon (Simon edition, 1977) is a twentieth-century invention with no connection to genuine medieval magic. It borrows names from H. P. Lovecraft’s fiction. Davies covers it in Grimoires as an example of modern grimoire manufacture; it belongs to the history of publishing, not the history of magic.

The Book of Shadows as transmitted in Gardnerian Wicca was composed primarily by Gerald Gardner and Doreen Valiente in the mid-twentieth century, drawing on Crowley, the Golden Dawn, and other sources. It is a legitimate twentieth-century ritual text with genuine depth. It is not “ancient.” The work of Ronald Hutton (Triumph of the Moon, 1999) documents this clearly.

The Grand Grimoire and related French popular grimoires that claim fifteenth or sixteenth-century dates are generally later — most surviving copies postdate their stated composition dates by a century or more, and the claimed lineages do not hold up to manuscript analysis.

The pattern across all three is the same one that runs through the genre from the beginning: claimed antiquity as a credential. The honest response is not to dismiss the texts but to read the credentials skeptically and the content on its own terms.

Where to go from here

The natural next step from this page is the companion guide on Reading Old Grimoires — how to approach a historical magical text practically: what to take at face value, what to bracket, how to work the gap between the historical context and your own.

For specific texts: the Key of Solomon correspondence page on this site will cross-reference planetary pentacles and their relationship to the modern correspondence system. The Picatrix’s system of planetary suffumigations is one of the most coherent pre-modern frameworks for working with incense as a magical material.

The grimoire tradition is not a monument. It is a working archive — one that was always being added to, revised, and argued with. That is the part that tends to get lost in the romance of the locked and leather-bound.
