43 paintings you need to see before you die

In an old barn that Jackson Pollock transformed into a studio, the artist laid his massive canvas on the wooden plank floor. He hurled white, yellow, blue, and black paint with sticks and knives at it. As he finished, he pressed his cigarette butt into the canvas, dripping with color.

This is how Pollock produced "Number 1," a painting that helped define Abstract Expressionism.

"He made everyone aware of the potential of letting paint have its own way and the overall impact of a painting without any configuration," Thomas Crow, Associate Provost for the Arts at New York University, told Business Insider.

These are the must-see paintings from Pollock and other painters who transformed the world of painting, from the prehistoric era to today.
