Quote from Cezanne's letter to Camille Pissarro, from L'Estaque 2 July 1876, taken from Alex Danchev, The Letters of Paul Cézanne, 2013; as quoted in the 'Daily Beast' online, 13 Oct. 2013 https://www.thedailybeast.com/cezannes-letter-to-pissarro-picture-business-isnt-going-well
'The very opposite of 'modeling' meant roughly that Cézanne and Pissarro in their common painting-years in open air would lay down one plane or patch of color next to another in the painting, without any 'modeling' or shading between them - so that it looked as if each component part of the painting could be picked up from the canvas a little like a 'playing card from the table', as Cezanne explains here.
