The Glass Delusion and Silver Stain plus a Rollercoasting Video Trailer

There’s a fascinating article in the History Of Psychiatry (Volume 1, No. 2, 191 – 206, 1990 to be precise) about a type of delusion that was widely reported in the 15th to 17th centuries but rarely occurs in modern times.

  • Glass
  • Buttocks
  • Rene Descartes

This is such an excellent question, we’ll approach the answer from several different directions.
