Glasya-Labolas appears in the major European grimoire compilations of the sixteenth and seventeenth centuries, cataloged as the President and Earl of the Goetia's infernal hierarchy. The spirit commands 36 legions and holds dominion over matters of teaches sciences and hidden secrets.
The name Glasya-Labolas does not appear in pre-medieval sources with certainty, suggesting this spirit may represent a later codification of older folk beliefs about elemental air spirits, planetary mercury intelligences, or localized spirits of place that were systematized during the great period of grimoire compilation.
