Curiosa: New Vocabulary

Hip-deep in bibliographic description of seventeenth- and eighteenth-century texts on law and magic, which it is my task to convert into database-ready copy, I stumbled across the following Library of Congress subject heading:

Medicine, Magic, mystic, and spagiric.

Since the text in question is concerned with "curing magical and cabalistic illness" (if I'm translating the Latin correctly), the subject appeared to suit, but I was left asking, "What the heck does 'spagiric' mean?" As it turns out, "alchemical" -- and it seems to be derived from a Latin term invented by Paracelsus, spagiricus (thanks, OED!). Huh. Must file that away for possible use in FMA 'fic.
