Herbarium Arcanum

An old herbal open by candlelight

Sacred Herbology · a herbal of the occult virtues

The sacred plants from A to Z, one illuminated leaf each, with the planet that rules it, the rites it was used in and the compounds it contains.

In preparation · first leaves under way

The old herbals put the heavens and the plant on the same page. Agrippa gave each herb its planet. Culpeper gave it a ruler and a sign. The Picatrix told the operator which plant to burn under which hour. The Herbarium Arcanum goes through the plants one at a time, from aconite to yew, and puts the old rulerships next to the chemistry.

What each leaf holds

  • The plateThe whole plant painted in watercolour and gold, root to flower, drawn true to the living specimen.
  • RulershipsThe planet and sign given to the plant, with the author who gave them, since Agrippa and Culpeper do not always agree.
  • The traditionsWhere the plant turns up in the grimoires, the temple recipes and the folk rites, quoted from the editions.
  • The chemistryThe compounds behind the reputation, drawn out as structures.
  • SourcesEvery claim traced to a published edition you can check.

The first leaves are being painted and written now, and the rest follow in alphabetical order. The Herbarium records tradition and history. It doesn’t offer anything as medicine.
