Lucien Pissarro recalled that Cézanne borrowed a painting from his father. He recalled: "Cézanne gives a clear definition of 'sensation' which really comes from my father. You know that Cézanne did most powerful black pictures until he came to ssee us in 1870: my father then explained to him what he was doing. Cézanne, in order to realise his meaning, asked father to lend him a picture to copy. The copy was very fine, and quite different from father's model – Cézanne always did that – his copy was a free one he copied everything except the actual execution. I have seen them hanging together in the collection of Dr. Gachet." (See J. Bensusan-Butt, 1977 or Rewald, 1996, p. 144).
