What the volume contains
Sloane MS 3648 is a physical British Library volume rather than a standard text of the Lesser Key. The library catalogue identifies a Lemegeton component at folios 1–47 and records extracts associated with Agrippa and Paracelsus later in the volume. Those neighboring works matter because the bound object holds more than one textual tradition. The shelfmark identifies the whole volume, while the folio range locates the Lemegeton material within it. A seal or spirit name found elsewhere under the broad title Lesser Key cannot automatically be assigned to this particular copy.
A compilation changes the meaning of “the Lesser Key”
The volume-level contents complicate the modern habit of treating the Lesser Key as a single self-contained book. Its Lemegeton material occupies one part of a codex that also preserves extracts associated with Agrippa and Paracelsus. That arrangement places a catalogue of spirits beside theoretical and medical-alchemical authorities, so the manuscript behaves like a selected working library rather than an authorial fair copy. The change of text at a folio boundary is analytical evidence: it shows which materials a compiler thought worth keeping together without proving that they came from one source. The codex therefore preserves two levels of organization at once; the internal order of the Lemegeton material and the later collector’s decision to bind it with other traditions.
Worked example: how a spirit entry compresses an operation
An Ars Goetia entry is a compact technical unit. Rank establishes a spirit’s place in the hierarchy; the appearance gives the operator a recognition test; the office states what the spirit is said to do; the legion count measures command; and the seal turns the entry into something that can be drawn. Those parts are not decorative equivalents. A spelling change may only alter a name, while a missing office changes the purpose of the entry and a damaged seal changes its graphic identifier. Reading the witness closely therefore means separating verbal, numerical, and visual variants. A modern alphabetical list hides this structure because it makes every record look like an encyclopedia entry rather than one component in a repeated ritual sequence.
What a missing line can change
The most consequential variants are rarely the most visually dramatic. A copied seal may remain recognizable while a dropped phrase removes a constraint, a direction, or part of an office. Conversely, an unfamiliar spelling can be harmless when the rank, seal, and surrounding sequence still identify the same entry. The useful comparison is layered: first the position of the spirit in the list, then the title and office, then the retinue or legion count, and finally the figure. Agreement across several layers can identify a relationship even when one layer fails. That method explains why the manuscript witnesses can support the same compilation history without yielding an identical modern text.
The neighboring extracts expose a theory-practice seam
Agrippan or Paracelsian extracts beside the Lemegeton create a seam between explanatory authority and enumerated procedure. A theoretical passage can supply reasons for celestial sympathy, characters, or spirit classes, while the catalogue supplies named entries ready for use. The seam is analytically productive because it shows that a compiler did not need one text to do both jobs. Modern editions often smooth this division by adding introductions and cross-references of their own. The manuscript instead lets the juxtaposition remain visible: one textual unit explains a world, another sorts its inhabitants, and the later bound volume makes the reader perform the connection.
Differences between the Lemegeton copies
Joseph H. Peterson treats Sloane 3648 and Sloane 3825 as witnesses to the same compilation. He discusses variant spellings, shortened passages, and physical trimming. These differences help explain why two lists of names can disagree while both trace back to manuscript material. An absent word might reflect scribal omission, a later normalization, or damage to one copy. Peterson’s assessment of errors concerns particular readings, not the age or quality of every image in the codex. The two Sloane volumes remain distinct objects with their own contents and copying histories.
A conflict in the catalogue descriptions
The current British Library summary labels the Lemegeton portion “1572” and “Fr.” Peterson, by contrast, describes Sloane 3648 as an English seventeenth-century Lemegeton witness. The brief online descriptions do not explain that difference or clarify the date’s scope. The disagreement also affects language: “Fr.” in the catalogue sits uneasily beside Peterson’s English description. Neither label can confidently be extended to every text bound in the volume. The mismatch is part of the present record for Sloane 3648 and leaves its dating and linguistic description less straightforward than the shelfmark alone suggests.
