The Quixote is a classic Spanish novel by the writer Miguel de Cervantes Saavedra. It depicts the madness of the central character, Don Quixote de la Mancha, who, by dint of reading the novels of chivalry, identified with them and believed himself to be a knight. Thus he goes in search of adventures with the sole purpose of perfecting the world as is the custom among knights. But beyond the madness of the central character, several other forms of madness emerge in the image of the madness of Chrysostom, Anselm and Cardenio. These various forms of madness which were the object of our study in this work have a psychic direction. Indeed, the madness in the Quixote is according to the terms of Mauron "a component of the personal myth" of the author, on the one hand, on the other hand, it is the expression of the unconscious in the functioning of the human psyche.
