A Sunday Afternoon on the Island of La Grande Jatte, 1884-86, Georges Seurat
”Seurat was a child of late nineteenth century scientific optimism. Thanks to the periodic table of elements it seemed that man now knew all the constituent parts of reality - the very building blocks of matter. Could one dissect sight down to its minutest particles, and so construct an objective grammer of seeing? Seurat believed one could, and his theory was based on scientific studies of colour analysis and visual perception. Of these, the one that influenced him most was The Law of Simultaneous Colour Contrast, 1839, by Eugene Chevreul. Local colour, Chevreul had shown, was mixed on the eye. A spot of pure colour gave the retineal impression of a halo of its complementary around it: orange rimmed with blue, for instance, red with green, purple with yellow. The interference of these aureoles meant that each colour changes its neighbour. Colour perception is therefore a matter of interaction, a web of connected events, rather than a presentation of one hue after another to the eye. Seurat resolved to make this explicit by making his colour patches tiny, reducing them to dots: hence the name, Pointillism. Stippled side by side, the dots grew by the million like coral polyps, and (like those tiny creatures) coalesced into a stiff deposit, a composed reef of form…In La Grande Jatte, the vision of pleasure takes on the gravity of historical painting. In constructing this large, elaborate space, Seurat gave every detail the degree of thought one might expect from Raphael or Piero della Francesca. It is linked together by rhymes and chords of shape…The monkey’s tail emulates the hook of the dandy’s cane. The decorum of posture and gesture, the distances people preserve between one another on that green abstracted lawn of Paradise, are turned into the decorum of classical art itself: manners elevated to aesthetics.”
