Provenance
Gusion appears in Weyer as Gusoyn or Gusoin, a strong great duke, within the same tradition of offices inherited by the Ars Goetia. The Goetia preserves him as the eleventh spirit, with variation of name and with the obscure form called xenophilus or zenocephalus in some readings. Already attested in the Livre des Esperitz (15th c.) as «Gazon (f180v)».
The seal: printed edition and facsimile
Gusion's main seal follows the printed Mathers–Crowley (1904) form; the Sloane MS 2731 manuscript facsimile is shown separately for comparison.
The main image and SVG/PNG downloads reproduce the printed form of S. L. MacGregor Mathers and Aleister Crowley's 1904 edition, using the normal vector pack documented on Wikimedia Commons (public domain/CC0). The Sloane MS 2731 facsimile remains separate for comparing manuscript variants; it is not used as the main image.
The FULL manuscript facsimile («Lemegeton, Clavicula Salomonis», Sloane MS 2731) is in our library; the original is held at the British Library (Sloane MS 2731).
How it is summoned
In antiquity
According to the Ars Goetia, the operation is the same for all 72 spirits:
- The magician draws the magic Circle and never steps out of it during the whole work.
- A few paces away he draws the Triangle of Art: there, and only there, must the spirit manifest.
- On his breast he wears the lamen bearing the demon's seal, engraved in metal.
- He recites the conjurations, calling it by its names and by the divine names.
- If the spirit resists or delays, the constraint and the 'chain of spirits' are used.
- Once the request is granted, he gives it the license to depart, and never before.
The ancient sources attribute to him the answering of past, present, and future matters, the clarification of questions, the reconciliation of friendships, and the granting of honor and dignity. They assign him no operative orientation, astrological time, offering, or caution of his own.

The common Goetic operation also adds, when needed: to constrain a resisting spirit (Wellcome MS 110, c74–c78), to show it the Pentacle of Solomon once manifested (Ars Theurgia-Goetia), to work in its planetary hour and day (by rank), and finally to give it licence to depart —and never before (Wellcome MS 110, c53). Practise the full rite at The Practitioner's Table.
What is the “chain of spirits”?
Modern · not ancient
- Print or draw its seal and place it before you on a clean surface.
- Light a candle and, if you wish, some incense; still your mind and set your intention.
- Intone its enn softly and repeatedly, eyes on the seal, until you feel a shift in the air.
- State your request clearly and respectfully, not as a command.
- Give thanks, let the candle burn down a little and close; modern practice is devotional, with no coercive conjuration.
Enn (modern chant): «Secore vesa anet Gusion»
Source: Enn of modern demonolatry (lists disseminated by S. Connolly, The Complete Book of Demonolatry, 2006)
His modern use concentrates on reconciliation, prestige, and divination, extending his Goetic functions without an ancient rite of his own.
Modern experiences (personal gnosis)
In contemporary demonolatry (as documented in S. Connolly's 'The Daemonolatry Goetia'), Gusion is typically worked with primarily to reconcile broken friendships, diffuse social tensions, and gain respect in professional environments. Practitioners describe his presence as diplomatic, steady, and straightforward, and he is highly valued for his ability to offer objective clarity on interpersonal conflicts without the overwhelming intensity characteristic of other Goetic spirits.
Personal gnosis (UPG): how contemporary practitioners say they experience it. This is subjective experience, not a historical source or doctrine; it does not come from the ancient grimoires and may not be real.
