"Bedlam", "scandal" and "hilarity" were among the epithets used to describe the effect of what is now considered Georges Seurat's greatest work, and one of the most remarkable paintings of the 19th century, when it was first exhibited in Paris in 1886. "A Sunday on La Grande Jatte - 1884", an extensive landscape peopled with over 40 figures, took the artist almost two years to complete. Inspired by research in optical and colour theory, Seurat juxtaposed tiny dots of colours on the canvas that form a single and more brilliantly luminous hue in the viewer's eye. This book, created to accompany a major exhibition at the Art Institute of Chicago, provides an in-depth examination of the gestation, execution and influence of Seurat's masterpiece. "La Grande Jatte" has been part of the Art Institute of Chicago's collection since 1926. Bringing together all known studies and drawings directly related to the painting, this volume provides a visual and contextual survey of Seurat's working methods and aesthetic priorities, as well as the evolutionary process that culminated in his singular achievement. Included are more than 55 prepartory works, ranging from rich conte crayon drawings to oil sketches on small wood panels to larger studies painted on canvas. In their quantity, intricacy and variety, these works reveal a compositional process that harks back to Old Master traditions and methods, which had been largely abandoned by Seurat's immediate predecessors, the Impressionists. The many studies attest to the artist's ambitions for his masterpiece and open up a broader context for understanding the painting. Robert L. Herbert, who has written extensively on the artist, traces Seurat's beginnings in the context of Barbizon painting and Impressionism. Works by Monet, Pissarro and Renoir are included, as well as a discussion of "La Grande Jatte"'s influence on contemporary art and Seurat's impact on 20th-century artists such as Leger and others from the School of Paris. An accompanying essay by Neil Harris assesses "La Grande Jatte"'s iconic status in Chicago and beyond, considering a history of the painting's promotion, presentation and exhibition. The book provides proof of why La Grande Jatte is among the most frequently reproduced paintings in the world and why it continues to fascinate scholars and art lovers today.
