[The cholera, and the fictionalized novel writted by Giono in Le hussard sur le toit].

We are going to confront the scientific description of the cholera and how to prevent and cure it, with the approach described by Giono in his writing. With the character's psychology, he chooses, the author enriches the human psychodynamic way to face the epidemic. The expanded affects, the fear of death, the drive and the willingness to live, the group reactions, originate in this fear of the unknown, as a remnant of the birth trauma, where the desire follows the drive.
