Action painting, sometimes called "gestural abstraction", is a style of painting in which paint is spontaneously dribbled, splashed or smeared onto the canvas, rather than being carefully applied. The resulting work often emphasizes the physical act of painting itself as an essential aspect of the finished work or concern of its artist.
The style was widespread from the 1940s until the early 1960s, and is closely associated with abstract expressionism (some critics have used the terms "action painting" and "abstract expressionism" interchangeably). A comparison is often drawn between the American action painting and the French tachisme.
The term was coined by the American critic Harold Rosenberg in 1952, in his essay "The American Action Painters", and signaled a major shift in the aesthetic perspective of New York School painters and critics. According to Rosenberg the canvas was "an arena in which to act". While abstract expressionists such as Jackson Pollock, Franz Kline and Willem de Kooning had long been outspoken in their view of a painting as an arena within which to come to terms with the act of creation, earlier critics sympathetic to their cause, like Clement Greenberg, focused on their works' "objectness." To Greenberg, it was the physicality of the paintings' clotted and oil-caked surfaces that was the key to understanding them. "Some of the labels that became attached to Abstract Expressionism, like "informel" and "Action Painting," definitely implied this; one was given to understand that what was involved was an utterly new kind of art that was no longer art in any accepted sense. This was, of course, absurd." – Clement Greenberg, "Post Painterly Abstraction".
Rosenberg's critique shifted the emphasis from the object to the struggle itself, with the finished painting being only the physical manifestation, a kind of residue, of the actual work of art, which was in the act or process of the painting's creation. The newer research tends to put the exile-surrealist Wolfgang Paalen in the position of the artist and theoretician who used the term "action" at first in this sense and fostered the theory of the subjective struggle with it. In his theory of the viewer-dependent possibility space, in which the artist "acts" like in an ecstatic ritual, Paalen considers ideas of quantum mechanics, as well as idiosyncratic interpretations of the totemic vision and the spatial structure of native-Indian painting from British Columbia. His long essay Totem Art(1943) had considerable influence on such artists as Martha Graham, Isamu Noguchi, Jackson Pollock, Mark Rothko and Barnett Newman; Paalen describes a highly artistic vision of totemic art as part of a ritual "action" with psychic links to generic memory and matrilinear ancestor-worship.
