While researching the material in the Leipzig manuscripts I was lucky enough to stumble upon (and by stumble upon I mean dig ferociously through boring lists, academic footnotes and records fueled by coffee) a very interesting manuscript.
Seal of Gemini, Pseudo-Arnoldus de Villanova
It s far older than the Leipzig collection but has a few treatises in common and it is one of the most complete (pun not intended, the manuscript is damaged) collections of image magic treatises, full of talismans and pentacles and seals.
The manuscript can be viewed HERE and you can download full quality images for free from the library, free of copyright. One of the most astounding policies regarding scanned manuscripts I have ever encountered.
Seal of Gemini, my rendition, based on the manuscript. These were not redrawn or based loosely on the drawings, but cleaned up and colored.
The title it bears is Clavicula Salmonis en andere magische tractaten en voorschriften but it does not contain any material from the Clavicles.
This is the description i found on Ptolemaeus :
