Theory of the Tache in Nineteenth-Century Painting - Sjastad, Oystein

Without question, the tache (blot, patch, stain) is a central and recurring motif in nineteenth-century modernist painting. Manet's and the Impressionists' rejection of academic finish produced a surface where the strokes of paint were presented directly, as patches or blots, then indirectly as legible signs. Cezanne, Seurat.
