Stolas

In antiquity

According to the Ars Goetia, the operation is the same for all 72 spirits:

1. The magician draws the magic Circle and never steps out of it during the whole work.
2. A few paces away he draws the Triangle of Art: there, and only there, must the spirit manifest.
3. On his breast he wears the lamen bearing the demon's seal, engraved in metal.
4. He recites the conjurations, calling it by its names and by the divine names.
5. If the spirit resists or delays, the constraint and the 'chain of spirits' are used.
6. Once the request is granted, he gives it the license to depart, and never before.

The tradition gives him no cardinal orientation, planetary timing, necessary offering, or individual ritual precaution.

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.

Modern · not ancient

1. Print or draw its seal and place it before you on a clean surface.
2. Light a candle and, if you wish, some incense; still your mind and set your intention.
3. Intone its enn softly and repeatedly, eyes on the seal, until you feel a shift in the air.
4. State your request clearly and respectfully, not as a command.
5. Give thanks, let the candle burn down a little and close; modern practice is devotional, with no coercive conjuration.

Modern practice usually uses him in devotional or meditative works linked to study, astronomy, plants, and stones; this does not derive from the ancient ritual.
