Jackson Pollock's masterpiece: 'No. 5, 1948'

It's easy to dismiss Jackson Pollock's No. 5, 1948 as a senseless splatter of paint-but even if you can't appreciate its aesthetic, this piece has a history that's worth its weight in house paint and stacks of cash. Here are some facts about the late artist's masterpiece.

It's a key work in the abstract expressionist movement: In the wake of World War II, New York City artists like Pollock, Barnett Newman, and Willem de Kooning began pushing the boundaries of their paintings in a direction that would be dubbed "Abstract Expressionism" by art critic Robert Coates in 1946. This wave of modern art made New York the center of the art world, thanks in part to the movement's embrace by esteemed collector and patron Peggy Guggenheim. Pollock's contribution was his drip paintings, of which No. 5, 1948 is his most famous.

Pollock used an unique method to make his drips: Rather than working from an easel, Pollock would place his canvas on the ground and pace around it, applying paint by dripping it from hardened brushes, sticks, and basting syringes. Pollock had only begun experimenting in this form the year before No. 5, 1948's creation, but his style soon became so signature he was dubbed "Jack the Dripper."  In 1947, he told the magazine Possibilities, "On the floor I am more at ease. I feel nearer, more part of the painting, since this way I can walk around it, work from the four sides, and literally be in the painting."

No.5, 1948 is a marker of the birth of action painting: Drip painting came to seen as a form of "action painting," which American art critic Harold Rosenberg defined in a 1952 essay, declaring, "Action Painting has to do with self-creation or self-definition or self-transcendence; but this dissociates it from self-expression, which assumes the acceptance of the ego as it is, with its wound and its magic."

Pollock didn't do any sketches or pre-planning for No. 5, 1948: Pollock's works were revolutionary on several levels. For centuries, artists had sketched out or test-run their large-scale paintings. But not Pollock, who was instead guided by emotion and intuition as he wove around his fiberboard base, dropping and flinging paint as his muse demanded. He abandoned brushstrokes in favor of drips and splashes, and set the art world on fire with his impromptu masterworks.

He used unconventional paints for No. 5, 1948: An important element of the drip method was paint with a fluid viscosity that would allow for smooth pouring. This requirement meant traditional oil paints and watercolors were out. Instead, Pollock began experimenting with synthetic gloss enamel paints that were making old-school, oil-based house paints obsolete. Though this clever innovation was praised, Pollock shrugged it off as "a natural growth out of a need."

For a time, No. 5, 1948 was the world's most expensive painting: On June 18, 2006, Gustav Klimt's Adele Bloch-Bauer I sold for $135 million, making it the highest priced painting in the world. Less than five months later, No. 5, 1948 fetched $140 million. In 2011, this title was snatched by one of Paul Cézanne's Card Players, with a price tag of $250 million.

It's a massive work: No. 5, 1948 measures in at 8 feet by 4 feet. The Guardian notes that this means each square foot is worth over $4 million. (Abridged) The writer is an entertainment journalist www.mentalfloss.com
