Enn: Ayer serpente Ose

From the Goetia:
“…appeareth like a Leopard at the first, but after a little time he putteth on the Shape of a Man. His Office is to make one cunning in the Liberal Sciences, and to give True Answers of Divine and Secret things; also to change a Man into any Shape that the Exorcist pleaseth, so that he is so changed will not think any other thing than that he is in verity that Creature or Thing he is changed into.”

Practical Uses:

• Languages & Technical Skills: Connolly recommends Osé for learning foreign languages and picking up workplace or computer skills quickly — handy for programmers or people switching disciplines.
• Shape-work & Psychodrama: His shape-changing office has obvious applications in practical shapeshifting work, psychodramatic ritual, glamouring, and deep role-play (including some forms of trance work where identity needs to be experienced, not merely imagined).
• Divination & Secret Knowledge: He can assist with answers to hidden questions and abstract problems tied to Mercury-type domains (communication, thought, language).

Mirta Wake traces the name to Latin os (mouth/speech), which fits his Mercurial, linguistic profile. He can, however, be dangerous for certain practitioners: Osé has the capacity to drive a person mad or to convince someone they are what they are not. Mirta Wake warns that Osé is not suitable for people using hallucinogens or other psychoactive substances — in her words, if you’re on a psychotropic trip, Osé can become your worst nightmare. The quick rule: approach only if you are mentally grounded, sober, and able to question the data you receive.

People who should work with Osé  are those with a strong will, clear critical faculties, sober, able to think for themselves, and comfortable questioning impressions during trance or possession work.

Those who should not are those who habitually rely on psychoactive substances for trance, the ungrounded, or anyone prone to dissociation or psychosis.

The leopard imagery carries a host of cultural readings — ferocity, stealth, multiplicity, and eyes-like-spots that symbolically “watch.” As with all symbolic material, interpret culturally and personally: the leopard that terrifies one magician may be the guardian to another. Osé’s leopard-shape suggests duplicity, masked observation, and an ability to occupy liminal identities.

If you plan to work with Osé for skill acquisition (languages/programming), frame petitions with measurable outcomes and include tests or exercises to confirm learning.

For shape-work, set strict contracts and protocols: time limits, clear anchor rituals to return to baseline, and a named senior guardian or threshold spirit on call.

Never mix Osé work with psychotropic substances. Keep grounding practices (breathwork, root visualisations, food/water) formalised before and after sessions.

Osé is a sharply Mercurial spirit: brilliant for language, cunning for craft, and risky where boundaries are loose. He’s an excellent practical ally for focused, sober practitioners who can maintain discernment while experimenting with provocative work such as shapeshifting or deep psychosomatic transformation. Approach with protocol, clarity of intent, and a sober mind.
