most accurate method of representing it in paint that he could find. To this end, he structurally ordered whatever he perceived into simple forms and colour planes. His statement "I want to make of impressionism something solid and lasting like the art in the museums", and his contention that he was recreating Poussin "after nature" underscored his desire to unite observation of nature with the permanence of classical composition. As with the old masters, for Cézanne the basis of painting was drawing, but the prerequisite for all work was subordination to the object, or the eye or pure looking: “All the painter’s intentions must be silent. He should silence all voices of prejudice. Forget! Forget! create silence! Be a perfect echo. […] The landscape is reflected, becomes human, thinks in me. […] I climb with her to the roots of the world. we germinate A tender excitement seizes me and from the roots of this excitement then rises the juice, the colour. I was born in the real world. I see! […] In order to paint that, then, the craft must be used, but a humble craft that obeys and is ready to transmit unconsciously.” In addition to oil paintings and watercolours, Cézanne left behind an extensive oeuvre of more than 1200 drawings, which, hidden in the cupboards and folders of the studio during his lifetime only began to interest collectors in the 1930s. They form the working material for his works and show detailed sketches, observation notes and traces of Cézanne's sometimes difficult to decipher stages on the way to the realization of the picture. Their task, linked to the process of creating the respective work, was to give the overall structure and the object designations within the pictorial organism. Even in old age, portraits and figure drawings were made based on models from antique sculptures and baroque paintings from the Louvre, which gave him clarity about the isolation of plastic phenomena. Therefore, the black and white of the drawings was an essential prerequisite for Cézanne's colour designs. Paul Cézanne was the first artist to begin breaking down objects into simple geometric shapes. In his much-quoted letter of 15 April 1904 to the painter and art theorist Émile Bernard, who had met Cézanne in his last years, he wrote: "Treat nature according to cylinder, sphere, and cone and put the whole in perspective, like this that each side of
