T. J. Clark, George C. and Helen N. Pardee Chair and professor of history of art, University of California, Berkeley. Centered on a group of paintings by Picasso from the 1920s, a series of six lectures traces the artist's path to Guernica. In this audio podcast of the sixth and final lecture, originally delivered at the National Gallery of Art on May 3, 2009, the renowned art historian and professor T. J. Clark reflects on the place of Guernica in Picasso's repeated attempts to escape from the intimacy and containment of cubism, and to expose his painting to everything in the new century that threatened to make that "interior" a thing of the past.
