Provenance
Furcas appears in Weyer (1577) as one of the spirits of the abbreviated catalogue deriving from the Liber Officiorum Spirituum. The Ars Goetia preserves him almost unaltered in office and appearance, marking him as the only Knight in its list. Already attested in the Liber Officiorum Spirituum (Folger V.b.26, 16th c.) as «Ansorvor vel Antyor (?)».
The seal: printed edition and facsimile
Furcas'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.
There is for him no singular rule of hour, direction, offering, or ceremonial precaution.
Source: Ars Goetia (17th c.); already in Weyer's Pseudomonarchia Daemonum, 1577
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 on ca Furcas remie»
Source: Enn of modern demonolatry (lists circulated by S. Connolly and Valerie Corban; tradition collected in The Complete Book of Demonolatry, 2006)
Its use as a repetitive chant belongs to contemporary demonolatry, not to the ancient Solomonic rite.
Modern experiences (personal gnosis)
In modern demonolatry, particularly according to S. Connolly's «The Daemonolatry Goetia», practitioners often work with Furcas to enhance their psychic abilities and master divinatory arts like chiromancy or pyromancy. His presence is described as that of a highly strict and demanding teacher, where the «cruelty» noted by classic grimoires is reinterpreted today as the intellectual severity of a relentless mentor.
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.
