sunday afternoon on the island of la grande jatte
The huge work (7 feet in height; 10 feet in width) caused a sensation. Not only did it exude a shimmering impression of warm, hazy sunshine, but the stylized, statuesque nature of its figure painting exuded a timeless and monumental quality. Unlike the fleeting naturalism of Monet (1840-1926) and Renoir (1841-1919), which captured the momentary perceptions of the artist, La Grande Jatte was painstakingly planned from start to finish in the manner of a Greek frieze, and its (often) symbolic content positively invites careful scrutiny.

Why did he dedicate so much time to these preparatory sketches? As Pointillists, Seurat and Signac were particularly interested in playing with perception and experiment with optics, resulting in a comprehensive and meticulous painting process.
In order to perfect his painting of the popular park, Seurat completed a collection of preliminary sketches and drawings. Taking a cue from the Impressionists, he created these studies away from his studio and en plein air. This approach enabled Seurat to capture the color, light, and movement of the scene before him, which he revisited several times before finishing the final large-scale painting in 1886.
Some of the characters are doing curious things. The lady on the right side has a monkey on a leash. A lady on the left near the river bank is fishing. The area was known at the time as being a place to procure prostitutes among the bourgeoisie, a likely allusion of the otherwise odd “fishing” rod. In the painting’s center stands a little girl dressed in white (who is not in a shadow), who stares directly at the viewer of the painting. This may be interpreted as someone who is silently questioning the audience: “What will become of these people and their class?” Seurat paints their prospects bleakly, cloaked as they are in shadow and suspicion of sin. 
The border of the painting is, unusually, in inverted color, as if the world around them is also slowly inverting from the way of life they have known. Seen in this context, the boy who bathes on the other side of the river bank at Asnières appears to be calling out to them, as if to say, “We are the future. Come and join us”.

A Sunday Afternoon on the Island of La Grande Jatte is one of those rare cases where a single artwork is able to stand out completely – its transcendence, both narratively and technically, is instinctively recognized by everyone.
Seurat’s style of painting broadly diverged from his school and upon leaving it he decided to travel to the Island of La Grande Jatte. It was here that he was to find the inspiration for his landmark work of art and cement his reputation as an artist forever.
Where the technique of pointillism shows its unique aspect is where the light from the left comes into contact with people and objects in the piece. The blend of such colors is pointillism’s primary concern and as its founder Seurat’s work epitomizes the technique.
