Orphism or Orphic cubism, is a term coined in 1912 France by the poet Guillaume Apollinaire. He used the French term Orphisme to label the paintings of Robert Delaunay, relating them to Orpheus, the poet and symbol of the arts of song and the lyre in Greek mythology. The term may also be used in reference to the paintings of Delaunay's wife, Sonia Terk and to the Czech painter, Frantisek Kupka along with other members of the Puteaux Group.
