The Martian Alphabet as received by Hélène Smith, from "India to the Mars Planet" by Théodore Flournoy, 1899.

André Breton writes: "The wondrous Elise Müller, better known under the pseudonym of Hélène Smith, presents successively automatic phenomena of verbal-auditive nature (she notes as best she can fragments of fictive conversation that reach her), of vocal nature (when in trance, she says words in an unknown language), of verbal-visual nature (she copies exotic symbols that appear to her) and of artistic nature (when in trance, she writes taking the place of one of her Martians)."
