Abstract: Is hypnotic suggestion capable of becoming a scientific object or tool? How does literary representation shed light on the functioning of suggestion or vice versa? These are some of the issues addressed in this article, based on a mirror reading between levels of narration and suggestive word transformations in "L’Œuf rouge”. We carry out a cross-analysis of the tale and its resonances in the scientific discourse on hypnotism, in order to highlight the fruitful reciprocity between hypnotic suggestion and novelistic reading at the end of the 19th century.
