"Orphism" was the name that writer Guillaume Apollinaire called paintings by Robert Delaunay that he saw in Paris around 1912. The "movement" was short, only a few years. In the years of the early 20th century many different approaches to art were seen in Dadaism, Cubism, etc. Some of the artists associated with those movements were also described in Orphism. So sculpture from artists associated with the other movements will be easier to identify, though I haven't found any specifically for Orphism. It seems as if only painters were referred to as Orphic.
