In ancient times, women who suffered from anxiety, depression and sudden mood swings were sent to the doctor. After an "examination", it was concluded that they suffered from "female hysteria".
To help combat this disease, a series of treatments were created, including "pelvic massage", with the aim of achieving what was then called "pelvic paroxysm", i.e. an orgasm.
Soon the treatment became popular and so many women went to the doctor to receive this treatment that a special device had to be created.
This artifact emitted rhythmic vibrations and massages, and in the beginning, well-to-do women or women from good families kept them in their homes in case an "episode of hysteria" occurred
This is how one of the first vibrators in history was created. A device that is still used today and that has clearly taken on a purely sexual connotation.
It is interesting how the vibrator emerged from an apparent disease and how the treatment quickly became popular.
