Our contributor Mark Lord experiences the Jasper Johns exhibit at Matthew Marks, and finds the highly charged subject of the work (a 1965 photo of a U.S. combat soldier weeping at the loss he could not prevent of friends in the war). He talks about the intimacy and emotion of the subject and how Johns removes the emotion for a reading about the mind distilling memory over time. The show is up through April 6 at the New York gallery.
