Initial release of Ars Theurgia-Goëtia is now up on Scribd. There are some minor typos I've already discovered since posting it, but not enough to currently warrant doing a full rebuild of the thing. Because the antiquated version of Word I'm using doesn't play nice with the vector graphics software I'm using (i.e. I can't simply copy and paste .svg vector objects from Inkscape into Word 2007), all figures have been turned into 300 dpi bitmaps.
Possibly going to take another stab at the remaining bits of Longobardus (i.e. my typeset of Sloane 3824). The only text still to be transcribed is the latter half of Trithemius Redivivus (about five leaves), but a large number of talismanic figures still remain to be redrawn (those forming the bulk of the second division of the codex, and a page embedded in the reworked Heptameron but nowhere explained or even mentioned in the text).
While working on the Theurgia-Goëtia I turned up a few things that suggest that the original redactor used Trithemius Redivivus (not the Sloane 3824 copy -- it has some errors in spirit names not found in the Lemegeton, not to mention it breaks off abruptly in ch. 13) rather than a printed Latin Steganographia. Specifically this is based on the rearrangements of some of the tables of "Dukes" under the chief spirits, which as set out in the 3824 copy do not generally preserve the arrangement from the printed Steganographia but are set out in two columns for day and night, and in the specific case of those under Raysiel, disarrange the order, displacing Lamas and Thurcal to the bottom of the list of nocturnal spirits, in which position they appear in the Theurgia-Goëtia (compare Sloane 3824 fol. 130r with p. 41 of the 1606 printing).
