Robert Delaunay, Endless Rhythm, 1934
From the Tate Gallery:
The coloured discs strung out diagonally across the picture are so arranged that each one leads on to the next and the movement is directed back again into the picture at the two ends. Perhaps because of this infinitely looping effect, his wife Sonia considered Endless Rhythm to be the most appropriate title. The year after painting this, Delaunay was commissioned to paint murals for the Aeronautics pavilion at the 1937 Paris International Exhibition; the resulting compositions included discs, rings and colour rhythms on a huge scale.
