Vapula

Vapula appears in the milieu of goetic grimoires and their modern derivatives: his name is recorded among the named spirits of the Ars Goetia tradition (see consolidated lists such as Wikipedia's list of demons in the Ars Goetia), and contemporary occult encyclopedias and blogs (e.g., Thelemapedia, LiberNeglecta) treat him as a ranked supernatural officer. The material at hand does not include an original manuscript quotation from the Ars Goetia or Pseudomonarchia Daemonum, but cites the goetic tradition as the provenance for Vapula's inclusion in lists of named, ranked spirits. Modern sources have adapted this persona into new contexts (encyclopedic entries, occult blogs, and role-playing/game writeups), framing Vapula as a bureaucratic, teachable spirit repurposed for contemporary themes such as technology and technical skill.

The provided sources do not supply a consistent, primary description of Vapula's physical form. Thelemapedia and other cited modern references identify his rank and functions but the excerpts supplied here lack a concrete bodily description; no reliable traditional iconography or description from an original Ars Goetia entry is present in the provided material, and therefore no canonical appearance can be asserted from these sources.

Across the cited materials Vapula is described primarily as an ordered specialist spirit and teacher: Thelemapedia identifies him as a powerful Great Duke who 'teaches ... and sciences' and commands thirty-six legions (fragmentary wording preserved in the excerpt). Modern commentary (LiberNeglecta/Book of the Neglected) frames him as a 'Prince of Technology' whose temperament inclines toward mechanical and analytical scrutiny — 'the world is an experiment gone awry — just waiting to be taken apart and examined, piece by piece, to see what broke.' Gaming and rolewriting sources (PathfinderWiki, IN NOMINE writeups, other RPG writeups) treat him as associated with technology, secrets, and technical arts. The corpus thus supports claims that Vapula functions as a patron/teacher of technical knowledge and commands subordinate spirits, but does not provide ritual conjurations or spells in the supplied excerpts.
