The Hundred Headless Woman is Ernst's first collage novel. It features a loosely narrative sequence of uncanny Surrealist collages, made by cutting up and reassembling nineteenth-century illustrations, accompanied by Ernst's equally strange captions. Ernst's French title, La Femme 100 têtes, is a double entendre; when read aloud it can be understood as either "the hundred-headed woman" or "the headless woman." Along with this enigmatic title character, the book marks the introduction of Ernst's favorite alter ego, Loplop, "the Bird Superior." Ernst was deeply engaged with illustrated books during the 1930s; in addition to collage novels, he created many etchings and lithographs to complement the poems and stories of Surrealist writers with whom he was closely associated.
