What is a seal in this catalog?
The Goetia assigns a graphic emblem to each of its 72 numbered spirits. The source usually calls it a seal; modern discussions also use sigil. Both words refer here to the historical drawing assigned to an entry.
A seal is one component of an entry, alongside a name, rank, description, and attributed office. Looking at the drawing beside the passage makes the source easier to study, but the drawing does not by itself establish the text’s supernatural claims.
The 1916 seal plates
The seals shown here come from numbered plates in the 1916 de Laurence edition digitized by Project Gutenberg. The descriptions follow the 1904 Mathers–Crowley text. A seal and the passage beside it therefore belong to different printed editions.
Each entry links to the printed source of its seal so the drawing can be compared with the plate and with variants in other copies.

Why the lines can differ
A seal can change as a manuscript is copied, edited, printed, or redrawn. The editor of the transcribed Goetia explicitly discusses deterioration and errors in sigils across codices. Two online images of the same spirit can therefore show different historically transmitted lines.
Uneven printing and scan marks can appear beside the drawn lines, complicating comparison with another edition.
