Paris-based abstract art movement most often referred to as Orphism , whose style featured loosely painted patches of rainbow colours. The name (Orpheus was a mythological poet and musician of ancient Greece) was coined by French art critic Guillaume Apollinaire when describing the 'musical' effect of the abstract paintings by the Cubist Robert Delaunay (which comprised overlapping planes of contrasting or complementary colours) in order to distinguish them from Cubism generally. Delaunay himself used the term Simultanism to characterize his work. Another exponent of Orphism was the French-Czech painter and anarchist Frank Kupka, one of the first to create genuine abstract art, characterized by solid geometric blocks of colour. The style was very similar to Synchromism , a method of painting launched in Paris in 1913 by two American painters, Morgan Russell (1886-1953) and Stanton MacDonald- Wright (1890-1973).
