Abstraction shook Western art to its core. In the early part of the 20th century, it refuted the reign of clear, indisputable forms and confronted audiences instead with vivid visual poems devoid of conventional representational imagery and characterized by allegories of emotion and sensation.

This radical artistic adventure established new artistic means, as much as narratives. Expression became characterized by shocking juxtapositions of color, light, and line. Artists abandoned the conventions of brush and easel and played with new materials and methods of artistic gesture: commercial paints and housepainter’s brushes, working on unstretched and unprimed canvases, moving the canvas to the floor, and applying paint with hands.

This essential introduction spans the international breadth, conceptual depth, and seismic impact of abstract art with a thorough survey not only of the big names such as Picasso, Klee, Kline, Rothko, and Pollock, but also lesser-known figures who made equally significant contributions, including Antoni Tàpies, K. O. Götz, Ad Reinhardt, and Sophie Taeuber-Arp.
