§ Introduction
Andrealphus is the Sixty-fifth Spirit in the Ars Goetia. Compared to many entries, his portfolio is unusually academic: geometry, measurement, and astronomical reasoning show up as core themes.
§ Grimoire Profile
Rank: Mighty Marquis
Legions: 30
Attributed office: Geometry, mensuration, astronomy
§ Appearance (Traditional Description)
The text describes an initial form as a peacock with "great noises," followed by a human shape. The peacock is a perfect medieval emblem for flamboyant display—fitting for a spirit linked to showy, intricate knowledge.
§ Powers and Attributions
- Teaching geometry "perfectly"
- Making people subtle in mensuration and astronomy
- Transforming a man "into the likeness of a bird" (a frequent magical image of altered state / altered identity)
§ Historical and Practical Context
Read historically, Andrealphus represents the era's belief that mathematics was not just practical—it was mystically structural, a key to how reality "locks together."
