The Golden Dawn (Regardie, 1937–40)

The publication that ended the secret. Four volumes: rituals, grade papers, Knowledge Lectures, the colour scales, the whole working apparatus of an order whose members were sworn not to reveal it.

Regardie's stated reason was preservation — the temples were dying and the material would go with them. He was denounced by surviving members and he was, on the evidence, right: almost every twentieth-century magical current that followed, and almost everything this wing is able to show you, exists in public because of this act.
