The crystalline disease described by Tannequin (or Thévenin?) Guillaumet, surgeon of Nîmes, is none other than syphilis. The author defines it as an unnatural indisposition, caused by poisonous vapour, by the mating of a man with a dirty woman, or by the opposite. He reports and examines a legend according to which this venereal disease would also be the consequence of cannibalistic acts.
