Suffused with light ...

Nighthawks Edward Hopper 1942

Suffused with light is the core essence of Edward Hopper's work, an elusive quality only a few great painters possess.

Hopper’s understanding of the expressive possibilities of light playing on simplified shapes gives the painting its beauty. Fluorescent lights had just come into use in the early 1940s, and the all-night diner emits an eerie glow, like a beacon on the dark street corner. Hopper eliminated any reference to an entrance, and the viewer, drawn to the light, is shut out from the scene by a seamless wedge of glass. The four anonymous and uncommunicative night owls seem as separate and remote from the viewer as they are from one another.
