One royal attribution covers two architectures
Clavicula Salomonis is the manuscript family presented in English by Mathers as the Key of Solomon. His 1889 edition arranges it in two books. Book I treats timing, operations, circles, conjurations, and pentacles; Book II treats purification, places, clothing, instruments, inks, incense, water, and related materials. The work builds a ritual procedure from dependencies among time, body, object, word, and space. Its chapters repeatedly point forward or backward across that two-book division.
The Lemegeton, commonly called the Lesser Key, is a compilation with a different macrostructure. Its familiar five-part scheme is Goetia, Theurgia-Goetia, Ars Paulina, Ars Almadel, and Ars Notoria. Those books catalogue different entities or arrange different celestial and devotional systems. The shared appeal to Solomon supplies authority, but it does not produce matching contents. “Greater” and “Lesser” can make the works sound like long and short editions of one manual; their tables of contents show that this is the wrong relationship.
The five Lesser Key books use different filing systems
Ars Goetia opens with a numbered catalogue of spirits described by rank, office, appearance, legions, and seal. Theurgia-Goetia shifts to aerial chiefs and ministers organized in a directional hierarchy. Ars Paulina has one division structured by the hours of day and night and another by degrees of the zodiac. Ars Almadel centers a marked wax table and four altitudes. Ars Notoria, where included, belongs to an older family of prayers and figures associated with learning. Calling all five “Goetia” erases four different organizing systems.
The variety also shows why the Lemegeton is a compilation rather than a continuous enlargement of the first book. A numbered spirit record, an hourly table, a zodiac-degree figure, a wax device, and a prayer for learning do not perform the same textual job. Copies can also preserve only some books, and the medieval Ars Notoria tradition predates its placement at the end of a Lesser Key sequence. The five-part list maps a recognizable received arrangement; it does not guarantee that every surviving volume contains five complete units in that order.
Worked comparison: pentacle operation and spirit record
A Key of Solomon pentacle operation begins outside the drawing. The edition assigns a planetary time, a material such as prepared paper or corresponding metal, colors, divine names, a purified place, incense, prayer, orientation, and storage. The image is one component in a timed material sequence. Book I explains its role and Book II supplies many prerequisites. Even a perfectly copied outline would omit most of what the text uses to define the object.
A Goetia entry organizes information differently. It identifies one spirit within a numbered series, gives a rank and described office, may narrate an appearance, counts legions, and pairs the record with an individual seal. The seal functions as the graphic identifier inside that catalogue. It is not a planetary pentacle transferred from the Clavicula, and the surrounding entry is not a chapter on making ritual materials. The parallel makes the difference concrete: the Key constructs an operation through dependencies, while Goetia constructs a roster through repeated records. Both use diagrams, but their diagrams inherit meaning from different textual structures.
Circles, pentacles, and seals have different graphic grammar
Mathers’s Plate I already contains several graphic categories. One figure is labeled the Mystical Figure of Solomon; another is a circle for consecrating pentacles with a central incense vessel and cardinal directions; a larger layout coordinates a central circle with four censers; two smaller linear characters stand apart. Later plates group planetary pentacles. The edition’s labels prevent these forms from collapsing into one universal “Solomon seal.” A circle can organize space, a pentacle can embody names and correspondences, and a tool character can mark an instrument.
The Lesser Key multiplies other graphic roles. Goetia seals distinguish spirit entries; Theurgia-Goetia seals belong to its aerial hierarchy; Ars Paulina figures correspond to hours or zodiac degrees; the Almadel drawing specifies a material device; Ars Notoria notae bind prayers to fields of learning. Similar rings, crosses, names, or stars can recur without proving that two images belong to the same operation. Graphic resemblance is one clue among structure, caption, neighboring prose, and manuscript sequence. The book containing the figure determines what kind of sign the reader is seeing.
Print history explains the naming drift
Mathers explicitly distinguishes the Lemegeton or Lesser Key from the work he is editing in his 1888 preface, while also describing seven differing Clavicula manuscripts behind his edition. That statement shows that the naming problem existed alongside the modern print tradition rather than arising only on websites. The editor presents one reconstructed Key, omits material he considers intrusive, normalizes some lettering, and organizes chapters that differed among his manuscript sources. His clean two-book print is already an editorial synthesis.
The Lesser Key developed through its own manuscript and publication history. The separately published Goetia later became the most visible part, encouraging its seventy-two seals to stand in for the entire compilation and sometimes for Solomonic magic generally. The correction is structural: Clavicula pages belong with Key manuscripts and Mathers’s pentacle plates; Goetia spirit pages belong with the first Lemegeton book; the other four Lesser Key books retain their own systems. Neither work is an autograph by the biblical Solomon. Their names record strategies of authority, while shelfmarks, imprints, contents, and diagrams reveal the historical objects readers actually inherited.
