I would like to talk about grimoires. Not a specific grimoire, like the Key of Solomon, or Heptameron, or Lemegeton. This isn’t even about their contents, or their history. No, what I want to talk about are the actual physical grimoires—those dangerous things made of paper and cardboard, with arcane scribbles of ink on their pages. Books that at various time and places (including to this very day) could get you arrested and worse.
