Bifrons

Bifrons does not have a mythic cosmogonic origin in the supplied sources; instead he appears as an entry in learned catalogues of spirits compiled by medieval and early‑modern demonologists and magicians. The sources place him within the taxonomy of named goetic spirits in texts such as the Lesser Key of Solomon (where he appears in the numbered list of spirits) and Johann Weyer's Pseudomonarchia Daemonum, and later reference works (e.g., Dictionnaire Infernal and modern encyclopedias) repeat that cataloged placement rather than offering a narrative origin.

The provided summaries do not supply a reliable, detailed physical description. Grimoire‑style listings that mention Bifrons (as in the Lesser Key and Pseudomonarchia summaries cited) typically emphasize rank, duties, and powers rather than full iconography; the available excerpts therefore do not permit a confident reconstruction of his visage or traditional depiction (uncertain).

Summaries in modern reference sources attribute to Bifrons the capacity to teach sciences and arts and to instruct in the virtues of gems, woods, and herbs. One modern summary also ascribes to him the ability to change or move corpses from their original graves to other places. These functions are reported in the context of grimoire entries that list powers a conjurer might compel; the exact wording and the scope of these abilities vary in the brief modern summaries available in the supplied materials.
