In page Walter Sickert:

"

Sickert often professed his distaste for what he termed the "beastly" character of thickly textured paint.[6] In an article he wrote for The Fortnightly Review in 1911, he described his reaction to the paintings of Van Gogh: "I execrate his treatment of the instrument I love, these strips of metallic paint that catch the light like so many dyed straws ... my teeth are set on edge".[6] In response to Alfred Wolmark's work he declared that "thick oil-paint is the most undecorative matter in the world".
