“Appolinaire [spokesman of French Cubism ] told me about a book of his on the Cubists that's about to come out. He divides the Cubists into Physical Cubists, (Gleize) [sic], who add some dramatic elements to their expression of external realities; Scientific Cubists (Picasso, Metzinger) and 'Orphiques' [sic]. (I give you [ Umberto Boccioni ] this last classification in French because I don't know how to translate it); in Appolinaire's opinion the 'Orphiques' [sic] seek new elements of expressing abstract realities; and we Futurists belong with the latter.”
