This work has an influence of Pointillism which Pissarro tested as an emerging "scientific" theory of art before creating this work.
Alexandre and Félix Fénéon were the first to use the term 'pointillism', in 1886, and Alexandre alone coined the term 'the Rouen School', in 1902 in a catalogue to an exhibition of the work of Joseph Delattre at the galerie Durand-Ruel à Paris.
In aesthetics, the beauty of La Grande Jatte might supervene on the physical composition of the painting (the specific molecules that make up the painting), the artistic composition of the painting (in this case, dots), the figures and forms of the painted image, or the painted canvas as a whole.
