I can see the black spots of the sun [remark to Sonia Delaunay, his wife and female artist]. - Robert Delaunay

This happened in 1912. Cubism was in full force. I made paintings that seemed like prisms compared to the Cubism my fellow artists were producing. I was the heretic of Cubism. I had great arguments with my comrades who banned color from their palette, depriving it of all elemental mobility. I was accused of returning to Impressionism, of making decorative paintings, etc.. .I felt I had almost reached my goal.

The need for a new subject has inspired the poets, launching them onto a fresh path and bringing to their attention to poetry of la Tour [the Eiffel tower in Paris], which communicates mysteriously with the whole world. Rays of light, waves of symphonic sounds. Factories, bridges, iron structures, airships, the numberless gyrations of aeroplanes, windows seen by crowd simultaneously.

On the other hand, the artist has much to do in the realm of color construction, which is so little explored and so obscure, and hardly dates back any farther than to the beginning of Impressionism.
