Gusion

Gusion appears in the catalog-style cosmology of the Ars Goetia, part of the Lesser Key of Solomon, where many nonhuman intelligences are listed with ranks and duties. Within that ritual-magical framework Gusion is presented as one of the rostered spirits that a magician might summon, interrogate, or command; the supplied sources do not provide a narrative origin myth or pre-grimoire legend for the entity, and they treat the name as transmitted through Latin/English grimoire compilations rather than as derived from a separately attested folkloric origin.

The provided materials do not include a direct, detailed physical description of Gusion from primary Ars Goetia texts. Secondary summaries characterize him in general terms (for example, as having a 'dignified and authoritative presence' in a fandom summary), but no concrete iconographic or bodily details are documented in the supplied sources.

In the grimoire-derived listings summarized in the available sources, Gusion is described as a high-ranking spirit (styled a 'Great Duke of Hell' in modern summaries and catalog entries) who commands many subordinate spirits and is attributed the ability to answer truthfully about the past, present, and future. The number '40 legions' is given in a later secondary summary drawing on Ars Goetia material; primary ritual texts and fuller attributions or step-by-step conjurations are not present among the supplied excerpts, so these capabilities are recorded here as functions reported in grimoire catalog tradition and later compendia rather than as independently corroborated by additional primary-source ritual instructions in the provided materials.
