La reine Mab is one of George Sand’s few poems. It was published for the first time on the 15th of December 1832 in the Soirées littéraires de Paris, in a keepsake edited by Madame Amable Tastu. Sand’s treatment of Queen Mab puts in place a thematic structure which will later, if we consider the whole of Sand’s novels, configure a specific representation of femininity which for the sake of practicality we will call the « Mab-woman ». Both muse and nymph, deeply ambiguous and ambivalent, this figure is less about the revelation of woman’s being than about her fantastical representation through a male gaze in which the Mab-Woman seems to be both object of an illusionary desire and, contradictorily, its mediator, while the illusionary character of the desire is eventually demonstrated and condemned by the truth of the novel.
